Warnings:
Warnings pediatric patients overdosage of antihistamines, particularly in infants and young children, may produce hallucinations, central nervous system depression, convulsions, respiratory and cardiac arrest, and death. antihistamines may diminish mental alertness; conversely, particularly, in the young child, they may occasionally produce excitation. cns depressants antihistamines may have additive effects with alcohol and other cns depressants, e.g., hypnotics, sedatives, tranquilizers, antianxiety agents. activities requiring mental alertness patients should be warned about engaging in activities requiring mental alertness and motor coordination, such as driving a car or operating machinery. antihistamines are more likely to cause dizziness, sedation, and hypotension in elderly patients (see precautions, geriatric use ).
Dosage and Administration:
Dosage and administration dosage should be individualized according to the needs and the response of the patient. each tablet contains 4 mg of cyproheptadine hydrochloride. pediatric patients age 2 to 6 years the total daily dosage for pediatric patients may be calculated on the basis of body weight or body area using approximately 0.25 mg/kg/day or 8 mg per square meter of body surface (8 mg/m 2 ). the usual dose is 2 mg (½ tablet) two or three times a day, adjusted as necessary to the size and response of the patient. the dose is not to exceed 12 mg a day. age 7 to 14 years the usual dose is 4 mg (1 tablet) two or three times a day adjusted as necessary to the size and response of the patient. the dose is not to exceed 16 mg a day. adults the total daily dose for adults should not exceed 0.5 mg/kg/day. the therapeutic range is 4 to 20 mg a day, with the majority of patients requiring 12 to 16 mg a day. an occasional patient may require as much as 32 mg a day for adequate relief. i

Contraindications:
Contraindications newborn or premature infants this drug should not be used in newborn or premature infants. nursing mothers because of the higher risk of antihistamines for infants generally and for newborns and prematures in particular, antihistamine therapy is contraindicated in nursing mothers. other conditions hypersensitivity to cyproheptadine and other drugs of similar chemical structure. monoamine oxidase inhibitor therapy (see drug interactions .) angle-closure glaucoma stenosing peptic ulcer symptomatic prostatic hypertrophy bladder neck obstruction pyloroduodenal obstruction elderly, debilitated patients
Adverse Reactions:
Adverse reactions adverse reactions which have been reported with the use of antihistamines are as follows: central nervous system sedation and sleepiness (often transient), dizziness, disturbed coordination, confusion, restlessness, excitation, nervousness, tremor, irritability, insomnia, paresthesias, neuritis, convulsions, euphoria, hallucinations, hysteria, faintness. integumentary allergic manifestation of rash and edema, excessive perspiration, urticaria, photosensitivity. special senses acute labyrinthitis, blurred vision, diplopia, vertigo, tinnitus. cardiovascular hypotension, palpitation, tachycardia, extrasystoles, anaphylactic shock. hematologic hemolytic anemia, leukopenia, agranulocytosis, thrombocytopenia. digestive system cholestasis, hepatic failure, hepatitis, hepatic function abnormality, dryness of mouth, epigastric distress, anorexia, nausea, vomiting, diarrhea, constipation, jaundice. genitourinary urinary frequency, difficult urination, urinary retention, early m

Overdosage:
Overdosage antihistamine overdosage reactions may vary from central nervous system depression to stimulation especially in pediatric patients. also, atropine-like signs and symptoms (dry mouth; fixed, dilated pupils; flushing, etc.) as well as gastrointestinal symptoms may occur. if vomiting has not occurred spontaneously, the patient should be induced to vomit with syrup of ipecac. if patient is unable to vomit, perform gastric lavage followed by activated charcoal. isotonic or ½ isotonic saline is the lavage of choice. precautions against aspiration must be taken especially in infants and children. when life threatening cns signs and symptoms are present, intravenous physostigmine salicylate may be considered. dosage and frequency of administration are dependent on age, clinical response, and recurrence after response. (see package circulars for physostigmine products.) saline cathartics, as milk of magnesia, by osmosis draw water into the bowel and, therefore, are valuable for their action in rapid dilution of bowel content. stimulants should not be used. vasopressors may be used to treat hypotension. the oral ld 50 of cyproheptadine is 123 mg/kg, and 295 mg/kg in the mouse and rat, respectively

Clinical Pharmacology:
Clinical pharmacology cyproheptadine is a serotonin and histamine antagonist with anticholinergic and sedative effects. antiserotonin and antihistamine drugs appear to compete with serotonin and histamine, respectively, for receptor sites. pharmacokinetics and metabolism after a single 4 mg oral dose of 14c-labelled cyproheptadine hcl in normal subjects, given as tablets, 2 to 20% of the radioactivity was excreted in the stools. only about 34% of the stool radioactivity was unchanged drug, corresponding to less than 5.7% of the dose. at least 40% of the administered radioactivity was excreted in the urine. no detectable amounts of unchanged drug were present in the urine of patients on chronic 12 to 20 mg daily doses. the principle metabolite found in human urine has been identified as a quaternary ammonium glucuronide conjugate of cyproheptadine. elimination is diminished in renal insufficiency.
