Orphenadrine Citrate



Class: Skeletal Muscle Relaxants, Miscellaneous
VA Class: MS200
CAS Number: 341-69-5
Brands: Norflex, Norgesic

Introduction

Skeletal muscle relaxant; tertiary amine antimuscarinic.a b c d k


Uses for Orphenadrine Citrate


Muscular Conditions


Used alone or in combination with aspirin and caffeine as an adjunct to rest, physical therapy, and other measures for the relief of discomfort associated with acute, painful musculoskeletal conditions.a b c k


For low back pain, generally reserve skeletal muscle relaxants for adjunctive treatment when pain is unresponsive to OTC analgesics (e.g., NSAIAs).d e f g h i


Skeletal muscle relaxants less well tolerated than NSAIAs, and clinical superiority to NSAIAs not established for low back pain.d e f g h i


Various skeletal muscle relaxants appear to have comparable efficacy for low back pain reliefj d and are more effective than placebo.d f h


Initially, symptomatic control of acute low back pain focuses on providing sufficient comfort to allow maximum possible activity while awaiting spontaneous recovery; later, as an aid to overcome specific activity intolerance.h


Because of rapid spontaneous recovery rate, efficacy of various therapies may be difficult to establish;h improvement of low back pain usually occurs within 2 weeks, substantial improvement within 4 weeks.g

Oral-B Minute Foam




Generic Name: sodium fluoride

Dosage Form: aerosol
Package.Label Principal Display Panel MINUTE-FOAM
Topical Fluoride Foaming Solution

(Acidulated Phosphate Fluoride Containing 1.23 % w/w Fluoride Ion)

FOR PROFESSIONAL USE ONLY

Active Ingredient:Acidulated Phosphate Fluoride (Sodium Fluoride and Hydrofluoric Acid) 1.23 % w/w fluoride ion.


DESCRIPTION:Oral-B Minute Foam is a flavored aqueous foaming solution of acidulated phosphate sodium fluoride with pH of 3.5 and a fluoride ion concentration of 1.23% w/w. Inactive Ingredients:Purified water, poloxamer 407, isobutane, poloxamer 234, phosphoric acid, sodium saccharin, flavor. CLINICAL PHARMACOLOGY: Acidulated Phosphate Fluoride inhibits caries formation by reducing enamel solubility and enhancing remineralization. INDICATION AND USE:A topically-applied foaming solution to aid in the prevention of dental caries. CONTRAINDICATIONS:      Do not use in patients with hypersensitivity to fluoride.

                                          Do not use in patients with dysphagia. WARNINGS: DO NOT SWALLOW

Accidental ingestion of the usual treatment dose (approx 12.4 mg of fluoride) is not harmful. In the event more than the treatment dose is swallowed, administer calcium (e.g. milk) and get medical or contact a Poison control Center right away. One bottle of Minute Foam contained 1.95 grams of fluoride ion which could be lethal for children adults.

Keep out of the reach of infants and children under 12 years.

Pediatric patients under age 12 should be supervised during use of this product.

Avoid spraying towards open flame.

Contents under pressure. Do not puncture or incinerate. Do not expose to heat or store at temperatures over 120 F (49 C).

PRECAUTIONS: FOR PROFESSIONAL USE ONLY

Laboratory studies have indicated that repeated use of Acidulated Phosphate Fluoride products may dull porcelain and composite restorations.


Safety and effectiveness below age 6 have not been established. There have been no long term studies with this product to evaluate carcinogenic, mutagenic or impairment of fertility potential.
Carcinogenesis, Mutagenesis, Impairment of Fertility:

No evidence of carcinogenicity was observed in female and male mice at doses ranging from 2.4 to 18.8 mg/kg sodium fluoride of body weight (3,4). Equivocal evidence of carcinogenicity was reported in male rats at doses ranging from 2.5 to 4.1 mg/kg fluoride, but no evidence of carcinogenicity was observed in female rates (3,4). In another study, no carcinogenicity was observed in rats treated with fluoride up to25 mg/kg of body weight (5). Overall, epidemiological studies do not show an association between fluoridated drinking water and increased cancer risks in humans (7).


Fluoride ion is not mutagenic in standard bacterial systems but has been associated with genetic aberrations in cultured human cells at doses much higher than expected for human exposure (6,8). Some in vivo studies report chromosomal aberrations in rodents while other studies using similar protocols report negative results (7).


Potential adverse reproductive effects of fluoride exposure in humans have not been adequately evaluated. Adverse reproductive effects of fluoride have been reported in animal studies, but at high concentrations sufficient to produce other manifestations of toxicity (9). Pregnancy:Teratogenic Effects: Pregnancy Category B. Fluoride readily crosses the placenta (7,9). Animal studies (rats and rabbits) have shown that fluoride is not a teratogen (10,12,13). Maternal exposure to 18 mg Fluoride/kg of body weight did not affect maternal body weight, litter size or fetal weight and did not increase frequency of skeletal or visceral malformations (10). There are no adequate and well-controlled studies in pregnant women. Several epidemiological studies show no increase in birth defects in areas with fluoridated water compared to areas with low fluoridated water (7). However, caution should be exercised when fluoride is administered to pregnant women. Nursing Mothers: Due to the relative insensitivity of human milk fluoride levels to changes in maternal fluoride intake, and due to the low concentrations of fluoride in human milk, fluoride supplementation during lactation would not be expected to significantly affect fluoride intake by the nursing infant (11). However, caution should be exercised when fluoride is administered to nursing women. Pediatric Use: The use of fluoride solutions, gels, and foams containing up to 1.23 % fluoride ion as caries preventives in pediatric patients aged 6 to 16 years is supported by clinical studies in students aged 6 to 12 years (1,2). Safety and effectiveness in pediatric patients below the age of 6 years has not been established. Please refer to CONTRAINDICATIONS and WARNINGS sections. Geriatric Use: No overall differences in safety or effectiveness have been observed between geriatric and younger patients. This drug is known to be substantially excreted by the kidney, therefore the risk of toxic reactions to this drug may be greater in patients with impaired renal function. Because elderly patients are more likely to have decreased renal function, care should be taken in dose selection, and it may be useful to monitor renal function. ADVERSE REACTIONS: Developing teeth of children under age 6 may become permanently discolored if excessive amounts are repeatedly swallowed. The following adverse reactions are possible in individuals hypersensitive to fluoride: eczema, atopic dermatitis, urticaria, gastric distress, headache and weakness OVERDOSAGE: Accidental ingestion of large amounts of fluoride can result in acute irritation of the mouth and gastrointestinal symptoms such as nausea, vomiting, diarrhea, hematemesis epigastric cramping and abdominal pain. If large amounts of fluoride equal to or greater than 5mg fluoride/kg body weight (or 2.3 mg fluoride/lb body weight) are ingested, give calcium (e.g. milk, 5% calcium gluconate or calcium lactate solution) orally to relieve gastrointestinal symptoms and admit immediately to a hospital facility.


A standard treatment dose of Minute-Foam contains approximately 12.4 mg fluoride. One 165 g (5.8oz) bottle contains approximately 1.95 g of fluoride. DOSAGE AND ADMINISTRATION: Adults and Children 6 years and over: Use foam 2 times a year.

This initial time you dispense from a new bottle, gently lift upward on the nozzle to break the protective seal (thin plastic located adjacent to trigger). If this seal is broken do not use the product.


Shake bottle vigorously for 3-4 seconds prior to dispensing.


Invert bottle 180 degree with nozzle tip pointed downward into tray.


Place nozzle tip close to the tray floor and at one end of the tray arch. Moving from one end of the tray to the other in one fluid motion, slowly press down on the trigger.


Dispense foam into applicator tray. (Note: foam will expand slightly to fill the tray.)


Immediately place trays in mouth. (Do not fill trays with foam too far in advance of treatment as the foam will collapse and not be as effective.)


Have patient bite down on the trays lightly but firmly for 4 minutes.


Remove trays and have patient expectorate excess.


Instruct patient not to eat, drink, or rinse for at least 30 minutes.


For optimal tooth coverage, use a fluoride applicator tray which is deep enough to reach the entire vertical height of all teeth (even the molars)

HOW SUPPLIED: Minute-Foam is available in a 165 g (5.8 oz) plastic aerosol container in six different flavors; NDC 0041-0340-06 Banana Splitz, NDC 0041-03141-06 Mellow Mint, NDC 0041-0342-06 Orang-a-Tangy, NDC 0041-0345-06 Bubblegum, NDC 0041-0346-06 Strawberry, NDC 0041-0347-06 Grape Punch.

What is Oral Pain Relief (benzocaine topical)?

Benzocaine is a local anesthetic (numbing medication). It works by blocking nerve signals in your body.


Benzocaine topical is used to reduce pain or discomfort caused by minor skin irritations, sore throat, sunburn, teething pain, vaginal or rectal irritation, ingrown toenails, hemorrhoids, and many other sources of minor pain on a surface of the body. Benzocaine is also used to numb the skin or surfaces inside the mouth, nose, throat, vagina, or rectum to lessen the pain of inserting a medical instrument such as a tube or speculum.


There are many brands and forms of benzocaine topical available and not all brands are listed on this leaflet.


Benzocaine topical may also be used for purposes not listed in this medication guide.


What is the most important information I should know about Oral Pain Relief (benzocaine topical)?


There are many brands and forms of benzocaine topical available and not all brands are listed on this leaflet.


Benzocaine topical used in the mouth or throat may cause a life-threatening condition in which the amount of oxygen in your blood stream becomes dangerously low. This condition is called methemoglobinemia (met-HEEM-oh glo-bin-EE-mee-a) and it may occur after only one use of benzocaine or after several uses.

Signs and symptoms of methemoglobinemia may occur within minutes or up to 2 hours after using benzocaine topical in the mouth or throat. GET EMERGENCY MEDICAL HELP IF YOU HAVE ANY OF THESE SYMPTOMS: headache, tired feeling, confusion, fast heart rate, and feeling light-headed or short of breath, with a pale, blue, or gray appearance of your skin, lips, or fingernails.


Do not use benzocaine topical if you have ever had methemoglobinemia in the past. Do not use this medicine on a child younger than 2 years old without medical advice. An overdose of numbing medications can cause fatal side effects if too much of the medicine is absorbed through your skin and into your blood. This is more likely to occur when using a numbing medicine without the advice of a medical doctor (such as during a cosmetic procedure like laser hair removal). Overdose symptoms may include uneven heartbeats, seizure (convulsions), coma, slowed breathing, or respiratory failure (breathing stops).

Use the smallest amount of this medication needed to numb the skin or relieve pain. Do not use large amounts of benzocaine topical, or cover treated skin areas with a bandage or plastic wrap without medical advice. Be aware that many cosmetic procedures are performed without a medical doctor present.


Your body may absorb more of this medication if you use too much, if you apply it over large skin areas, or if you apply heat, bandages, or plastic wrap to treated skin areas. Skin that is cut or irritated may also absorb more topical medication than healthy skin.

Before using benzocaine topical, tell your doctor if you have any type of inherited enzyme deficiency, heart disease, a breathing disorder such as asthma, bronchitis, or emphysema, or if you smoke.


If you are treating a sore throat, call your doctor if the pain is severe or lasts longer than 2 days, especially if you also develop a fever, headache, skin rash, swelling, nausea, vomiting, cough, or breathing problems.


What should I discuss with my health care provider before using Oral Pain Relief (benzocaine topical)?


Do not use benzocaine topical if you have ever had methemoglobinemia in the past. An overdose of numbing medications can cause fatal side effects if too much of the medicine is absorbed through your skin and into your blood. This is more likely to occur when using a numbing medicine without the advice of a medical doctor (such as during a cosmetic procedure like laser hair removal). Overdose symptoms may include uneven heartbeats, seizure (convulsions), coma, slowed breathing, or respiratory failure (breathing stops).

Ask a doctor or pharmacist if it is safe for you to take this medicine if you have:



  • asthma, bronchitis, emphysema, or other breathing disorder;




  • heart disease;




  • a personal or family history of methemoglobinemia, or any genetic (inherited) enzyme deficiency; or




  • if you smoke.




FDA pregnancy category C. It is not known whether benzocaine topical will harm an unborn baby. Tell your doctor if you are pregnant or plan to become pregnant while using this medication.. It is not known whether benzocaine topical passes into breast milk or if it could harm a nursing baby. Do not use this medication without telling your doctor if you are breast-feeding a baby. Do not use this medicine on a child younger than 2 years old without medical advice.

How should I use Oral Pain Relief (benzocaine topical)?


Use exactly as directed on the label, or as prescribed by your doctor. Do not use in larger or smaller amounts or for longer than recommended.


Your body may absorb more of this medication if you use too much, if you apply it over large skin areas, or if you apply heat, bandages, or plastic wrap to treated skin areas. Skin that is cut or irritated may also absorb more topical medication than healthy skin.

Use the smallest amount of medicine needed to numb the skin or relieve pain. Do not use large amounts of benzocaine topical, or cover treated skin areas with a bandage or plastic wrap without medical advice. Be aware that many cosmetic procedures are performed without a medical doctor present.


This medication comes with instructions for safe and effective application. Follow these directions carefully. Ask your doctor or pharmacist if you have any questions.


To treat minor skin conditions, apply a thin layer of benzocaine topical to the affected area up to 4 times per day. If using the spray, hold the container 6 to 12 inches away from the skin. Do not spray this medication onto your face. Spray it instead on your hands and then rub it onto the face, avoiding contact with your eyes.


To treat hemorrhoids, clean the area with soap and water before applying benzocaine topical. Apply the medication up to 6 times per day. If you are using the rectal suppository, try to empty your bowel and bladder before inserting the suppository. Remove the outer wrapper from the suppository before inserting it. Avoid handling the suppository too long or it will melt in your hands.


Do not use benzocaine topical to treat large skin areas or deep puncture wounds. Avoid using the medicine on skin that is raw or blistered, such as a severe burn or abrasion.

Call your doctor if your symptoms do not improve or if they get worse within the first 7 days of using benzocaine topical. Also call your doctor if your symptoms had cleared up but then came back.


If you are treating a sore throat, call your doctor if the pain is severe or lasts longer than 2 days, especially if you also develop a fever, headache, skin rash, swelling, nausea, vomiting, cough, or breathing problems.


Store at room temperature away from moisture and heat. Do not freeze.

What happens if I miss a dose?


Since benzocaine topical is used as needed, you may not be on a dosing schedule. If you are using the medication regularly, use the missed dose as soon as you remember. Skip the missed dose if it is almost time for your next scheduled dose. Do not use extra medicine to make up the missed dose.


What happens if I overdose?


Seek emergency medical attention or call the Poison Help line at 1-800-222-1222. An overdose of benzocaine topical applied to the skin can cause life-threatening side effects such as uneven heartbeats, seizure (convulsions), coma, slowed breathing, or respiratory failure (breathing stops).

What should I avoid while taking Oral Pain Relief (benzocaine topical)?


Avoid eating within 1 hour after using benzocaine topical on your gums or inside your mouth.


Benzocaine topical is for use only on the surface of your body, or just inside the mouth, vagina, or rectum. Avoid getting this medication in your eyes. Avoid swallowing the gel, liquid, or ointment while applying it to your gums or the inside of your mouth. The throat spray or oral lozenge may be swallowed gradually during use.

Do not apply other medications to the same affected areas you treat with benzocaine topical, unless your doctor has told you otherwise.


Oral Pain Relief (benzocaine topical) side effects


Benzocaine topical used in the mouth or throat may cause a life-threatening condition in which the amount of oxygen in your blood stream becomes dangerously low. This condition is called methemoglobinemia (met-HEEM-oh glo-bin-EE-mee-a) and it may occur after only one use of benzocaine or after several uses.

Signs and symptoms may occur within minutes or up to 2 hours after using benzocaine topical in the mouth or throat. GET EMERGENCY MEDICAL HELP IF YOU HAVE:

What is Orajel Maximum Strength (benzocaine topical)?

Benzocaine is a local anesthetic (numbing medication). It works by blocking nerve signals in your body.


Benzocaine topical is used to reduce pain or discomfort caused by minor skin irritations, sore throat, sunburn, teething pain, vaginal or rectal irritation, ingrown toenails, hemorrhoids, and many other sources of minor pain on a surface of the body. Benzocaine is also used to numb the skin or surfaces inside the mouth, nose, throat, vagina, or rectum to lessen the pain of inserting a medical instrument such as a tube or speculum.


There are many brands and forms of benzocaine topical available and not all brands are listed on this leaflet.


Benzocaine topical may also be used for purposes not listed in this medication guide.


What is the most important information I should know about Orajel Maximum Strength (benzocaine topical)?


There are many brands and forms of benzocaine topical available and not all brands are listed on this leaflet.


Benzocaine topical used in the mouth or throat may cause a life-threatening condition in which the amount of oxygen in your blood stream becomes dangerously low. This condition is called methemoglobinemia (met-HEEM-oh glo-bin-EE-mee-a) and it may occur after only one use of benzocaine or after several uses.

Signs and symptoms of methemoglobinemia may occur within minutes or up to 2 hours after using benzocaine topical in the mouth or throat. GET EMERGENCY MEDICAL HELP IF YOU HAVE ANY OF THESE SYMPTOMS: headache, tired feeling, confusion, fast heart rate, and feeling light-headed or short of breath, with a pale, blue, or gray appearance of your skin, lips, or fingernails.


Do not use benzocaine topical if you have ever had methemoglobinemia in the past. Do not use this medicine on a child younger than 2 years old without medical advice. An overdose of numbing medications can cause fatal side effects if too much of the medicine is absorbed through your skin and into your blood. This is more likely to occur when using a numbing medicine without the advice of a medical doctor (such as during a cosmetic procedure like laser hair removal). Overdose symptoms may include uneven heartbeats, seizure (convulsions), coma, slowed breathing, or respiratory failure (breathing stops).

Use the smallest amount of this medication needed to numb the skin or relieve pain. Do not use large amounts of benzocaine topical, or cover treated skin areas with a bandage or plastic wrap without medical advice. Be aware that many cosmetic procedures are performed without a medical doctor present.


Your body may absorb more of this medication if you use too much, if you apply it over large skin areas, or if you apply heat, bandages, or plastic wrap to treated skin areas. Skin that is cut or irritated may also absorb more topical medication than healthy skin.

Before using benzocaine topical, tell your doctor if you have any type of inherited enzyme deficiency, heart disease, a breathing disorder such as asthma, bronchitis, or emphysema, or if you smoke.


If you are treating a sore throat, call your doctor if the pain is severe or lasts longer than 2 days, especially if you also develop a fever, headache, skin rash, swelling, nausea, vomiting, cough, or breathing problems.


What should I discuss with my health care provider before using Orajel Maximum Strength (benzocaine topical)?


Do not use benzocaine topical if you have ever had methemoglobinemia in the past. An overdose of numbing medications can cause fatal side effects if too much of the medicine is absorbed through your skin and into your blood. This is more likely to occur when using a numbing medicine without the advice of a medical doctor (such as during a cosmetic procedure like laser hair removal). Overdose symptoms may include uneven heartbeats, seizure (convulsions), coma, slowed breathing, or respiratory failure (breathing stops).

Ask a doctor or pharmacist if it is safe for you to take this medicine if you have:



  • asthma, bronchitis, emphysema, or other breathing disorder;




  • heart disease;




  • a personal or family history of methemoglobinemia, or any genetic (inherited) enzyme deficiency; or




  • if you smoke.




FDA pregnancy category C. It is not known whether benzocaine topical will harm an unborn baby. Tell your doctor if you are pregnant or plan to become pregnant while using this medication.. It is not known whether benzocaine topical passes into breast milk or if it could harm a nursing baby. Do not use this medication without telling your doctor if you are breast-feeding a baby. Do not use this medicine on a child younger than 2 years old without medical advice.

How should I use Orajel Maximum Strength (benzocaine topical)?


Use exactly as directed on the label, or as prescribed by your doctor. Do not use in larger or smaller amounts or for longer than recommended.


Your body may absorb more of this medication if you use too much, if you apply it over large skin areas, or if you apply heat, bandages, or plastic wrap to treated skin areas. Skin that is cut or irritated may also absorb more topical medication than healthy skin.

Use the smallest amount of medicine needed to numb the skin or relieve pain. Do not use large amounts of benzocaine topical, or cover treated skin areas with a bandage or plastic wrap without medical advice. Be aware that many cosmetic procedures are performed without a medical doctor present.


This medication comes with instructions for safe and effective application. Follow these directions carefully. Ask your doctor or pharmacist if you have any questions.


To treat minor skin conditions, apply a thin layer of benzocaine topical to the affected area up to 4 times per day. If using the spray, hold the container 6 to 12 inches away from the skin. Do not spray this medication onto your face. Spray it instead on your hands and then rub it onto the face, avoiding contact with your eyes.


To treat hemorrhoids, clean the area with soap and water before applying benzocaine topical. Apply the medication up to 6 times per day. If you are using the rectal suppository, try to empty your bowel and bladder before inserting the suppository. Remove the outer wrapper from the suppository before inserting it. Avoid handling the suppository too long or it will melt in your hands.


Do not use benzocaine topical to treat large skin areas or deep puncture wounds. Avoid using the medicine on skin that is raw or blistered, such as a severe burn or abrasion.

Call your doctor if your symptoms do not improve or if they get worse within the first 7 days of using benzocaine topical. Also call your doctor if your symptoms had cleared up but then came back.


If you are treating a sore throat, call your doctor if the pain is severe or lasts longer than 2 days, especially if you also develop a fever, headache, skin rash, swelling, nausea, vomiting, cough, or breathing problems.


Store at room temperature away from moisture and heat. Do not freeze.

What happens if I miss a dose?


Since benzocaine topical is used as needed, you may not be on a dosing schedule. If you are using the medication regularly, use the missed dose as soon as you remember. Skip the missed dose if it is almost time for your next scheduled dose. Do not use extra medicine to make up the missed dose.


What happens if I overdose?


Seek emergency medical attention or call the Poison Help line at 1-800-222-1222. An overdose of benzocaine topical applied to the skin can cause life-threatening side effects such as uneven heartbeats, seizure (convulsions), coma, slowed breathing, or respiratory failure (breathing stops).

What should I avoid while taking Orajel Maximum Strength (benzocaine topical)?


Avoid eating within 1 hour after using benzocaine topical on your gums or inside your mouth.


Benzocaine topical is for use only on the surface of your body, or just inside the mouth, vagina, or rectum. Avoid getting this medication in your eyes. Avoid swallowing the gel, liquid, or ointment while applying it to your gums or the inside of your mouth. The throat spray or oral lozenge may be swallowed gradually during use.

Do not apply other medications to the same affected areas you treat with benzocaine topical, unless your doctor has told you otherwise.
