Indications and usage dimenhydrinate injection, usp is indicated for the prevention and treatment of nausea, vomiting, or vertigo of motion sickness.

Warnings caution should be used when dimenhydrinate is given in conjunction with certain antibiotics that may cause ototoxicity, since dimenhydrinate is capable of masking ototoxic symptoms, and an irreversible state may be reached. this drug may impair the mental and/or physical abilities required for the performance of potentially hazardous tasks, such as driving a vehicle or operating machinery. the concomitant use of alcohol or other central nervous system depressants may have an additive effect. therefore, patients should be warned accordingly. dimenhydrinate should be used with caution in patients having conditions which might be aggravated by anticholinergic therapy (i.e., prostatic hypertrophy, stenosing peptic ulcer, pyloroduodenal obstruction, bladder neck obstruction, narrow-angle glaucoma, bronchial asthma, or cardiac arrhythmias). the preparation should not be injected intra-arterially. pediatric patients for infants and children especially, antihistamines in overdosage ma Read more...

Pediatric patients for infants and children especially, antihistamines in overdosage may cause hallucinations, convulsions, or death. as in adults, antihistamines may diminish mental alertness in pediatric patients. in the young child, particularly, they may produce excitation (see contraindications ).

Dosage and administration dimenhydrinate in the injectable form is indicated when the oral form is impractical. adults nausea or vomiting may be expected to be controlled for approximately 4 hours with 50 mg, and prevented by a similar dose every 4 hours. its administration may be attended by some degree of drowsiness in some patients, and 100 mg every 4 hours may be given in conditions in which drowsiness is not objectionable or is even desirable. for intramuscular administration, each milliliter (50 mg) of solution is injected as needed, but for intravenous administration, each milliliter (50 mg) of solution must be diluted in 10 ml of 0.9% sodium chloride injection, usp and injected over a period of 2 minutes. pediatric for intramuscular administration, 1.25 mg/kg of body weight or 37.5 mg/m 2 of body surface area is administered four times daily. the maximum dose should not exceed 300 mg daily (see contraindications ). parenteral drug products should be inspected visually for parti Read more...

Adults nausea or vomiting may be expected to be controlled for approximately 4 hours with 50 mg, and prevented by a similar dose every 4 hours. its administration may be attended by some degree of drowsiness in some patients, and 100 mg every 4 hours may be given in conditions in which drowsiness is not objectionable or is even desirable. for intramuscular administration, each milliliter (50 mg) of solution is injected as needed, but for intravenous administration, each milliliter (50 mg) of solution must be diluted in 10 ml of 0.9% sodium chloride injection, usp and injected over a period of 2 minutes.

Pediatric for intramuscular administration, 1.25 mg/kg of body weight or 37.5 mg/m 2 of body surface area is administered four times daily. the maximum dose should not exceed 300 mg daily (see contraindications ). parenteral drug products should be inspected visually for particulate matter and discoloration prior to administration, whenever solution and container permit.

Contraindications neonates and patients with a history of hypersensitivity to dimenhydrinate or its components (diphenhydramine or 8-chlorotheophylline) should not be treated with dimenhydrinate. note: this product contains benzyl alcohol. benzyl alcohol has been associated with a fatal “gasping syndrome” in premature infants and infants of low birth weight.

Adverse reactions the most frequent adverse reaction to dimenhydrinate is drowsiness. dizziness may also occur. symptoms of dry mouth, nose and throat, blurred vision, difficult or painful urination, headache, anorexia, nervousness, restlessness or insomnia (especially in pediatric patients), skin rash, thickening of bronchial secretions, tachycardia, epigastric distress, lassitude, excitation, and nausea have been reported.

Pregnancy pregnancy category b. reproduction studies have been performed in rats at doses up to 20 times the human dose, and in rabbits at doses up to 25 times the human dose (on a mg/kg basis), and have revealed no evidence of impaired fertility or harm to the fetus due to dimenhydrinate. there are no adequate and well-controlled studies in pregnant women. however, clinical studies in pregnant women have not indicated that dimenhydrinate increases the risk of abnormalities when administered in any trimester of pregnancy. it would appear that the possibility of fetal harm is remote when the drug is used during pregnancy. nevertheless, because the studies in humans cannot rule out the possibility of harm, dimenhydrinate should be used during pregnancy only if clearly needed.

Overdosage drowsiness is the usual clinical side effect. convulsions, coma, and respiratory depression may occur with massive overdosage. no specific antidote is known. if respiratory depression occurs, mechanically assisted respiration should be initiated and oxygen should be administered. convulsions should be treated with appropriate doses of diazepam. phenobarbital (5 to 6 mg/kg) may be given to control convulsions in pediatric patients. the oral ld 50 in mice and rats is 203 mg/kg and 1320 mg/kg, respectively. the intraperitoneal ld 50 in mice is 149 mg/kg.
