Warner-Lambert Consumer Healthcare
Diphenhydramine HCl
Antihistaminic
Indications And Clinical Uses: Antihistamine, antiemetic and antispasmodic. Allergic diseases such as hay fever, allergic rhinitis, urticaria, angioedema, atopic dermatitis, contact dermatitis, gastrointestinal allergy, pruritus, physical allergies, reactions to injection of contrast media, reactions to therapeutic preparations and allergic transfusion reactions; also postoperative nausea and vomiting, motion sickness, and quieting emotionally disturbed children.
Contra-Indications: Cream should not be applied to extensively denuded or weeping skin areas.
Manufacturers’ Warnings In Clinical States: Antihistamines should be used with considerable caution in patients with narrow-angle glaucoma, stenosing peptic ulcer, pyloroduodenal obstruction, symptomatic prostatic hypertrophy, or bladder-neck obstruction. Not recommended for children with chronic lung disease or glaucoma.
Topical: For external use only. Do not use on chickenpox, measles or extensive areas of skin. If condition worsens or persists for more than 7 days, consult a physician. Do not use other drugs containing diphenhydramine while using this product.
Children: In infants and children, especially, antihistamines in overdosage may cause hallucinations, convulsions, or death. As in adults, antihistamines may diminish mental alertness in children. In the young child, particularly, they may produce excitation.
Geriatrics (approximately 60 years or older): Antihistamines are more likely to cause dizziness, sedation and hypotension in elderly patients.
Precautions: Pregnancy and Lactation: Safety for use in pregnancy and lactation has not been established. Its use therefore in such patients should involve consideration of expected benefits and possible risks.
Avoid s.c. or perivascular injection. Single parenteral dosage greater than 100 mg should be avoided, particularly in hypertension and cardiac disease.
Use as Local Anesthetic: This drug should not be used as a local anesthetic due to the risk of local tissue necrosis.
Occupational Hazards: Patients should be cautioned not to operate vehicles or hazardous machinery until their response to the drug has been determined.
Since the depressant effects of antihistamines are additive to those of other drugs affecting the CNS, patients should be cautioned against drinking alcoholic beverages or taking hypnotics, sedatives, psychotherapeutic agents or other drugs with CNS depressant effects during antihistaminic therapy.
Diphenhydramine has an atropine-like action and therefore should be used with caution in patients with a history of bronchial asthma, increased intraocular pressure, hyperthyroidism, cardiovascular disease or hypertension.
Adverse Reactions: Drowsiness, dizziness, dryness of mouth, nausea and nervousness may occur. Other infrequently reported effects are vertigo, palpitation, blurring of vision, headache, restlessness, insomnia and thickening of bronchial secretions. Allergic reactions, diarrhea, vomiting and excitation may also occur.
