Preparation H Ointment Disease Interactions

The use of laxatives is contraindicated in patients with inflammatory bowel disease. Patients with inflammatory bowel disease may experience colonic perforation with use of stimulant laxatives.

The use of laxatives is contraindicated in patients with intestinal obstruction disorders. Patients with intestinal obstruction disorders may need their underlying condition treated to correct the constipation. Some laxatives require reduction in the colon to their active form to be effective which may be a problem in patients with intestinal obstruction.

The use of stimulant laxatives is contraindicated in patients with or who may have acute surgical abdomen or appendicitis. These patients may be candidates for emergency surgery. Stimulant laxatives should also not be administered to patients with abdominal pain, particularly if the cause has not been determined.

The use of stimulant laxatives is contraindicated in patients with anal or rectal fissures. These preparations may cause irritation, burning sensation, and proctitis.

Topically applied sympathomimetic agents are systemically absorbed, with the potential for producing clinically significant systemic effects, particularly during prolonged or indiscriminate use. In cardiac tissues, these agents may produce positive chronotropic and inotropic effects via stimulation of beta-1 adrenergic receptors. Cardiac output, oxygen consumption, and the work of the heart may be increased. In the peripheral vasculature, vasoconstriction may occur via stimulation of alpha-1 adrenergic receptors. The use of topical sympathomimetic agents has rarely been associated with palpitations, tachycardia, arrhythmia, hypertension, reflex bradycardia, and coronary occlusion. Therapy with topical sympathomimetic agents should be administered cautiously in patients with sensitivity to sympathomimetic amines, hyperthyroidism, or underlying cardiovascular or cerebrovascular disorders, especially coronary insufficiency, cardiac arrhythmia, or hypertension.

Topically applied sympathomimetic agents are systemically absorbed, with the potential for producing clinically significant systemic effects, particularly during prolonged or indiscriminate use. In patients with prostate enlargement, urinary difficulty may develop or worsen due to smooth muscle contraction in the bladder neck via stimulation of alpha-1 adrenergic receptors. Therapy with topical sympathomimetic agents should be administered cautiously in patients with hypertrophy or neoplasm of the prostate. It is important that the recommended dosages of the individual products not be exceeded.

Topically applied sympathomimetic agents are systemically absorbed, particularly during prolonged or indiscriminate use. Slight increases in blood glucose concentrations may occur with the use of these drugs. Therapy with topical sympathomimetic agents should be administered cautiously in patients with diabetes mellitus. Closer monitoring of blood glucose concentrations may be appropriate. It is important that the recommended dosages of the individual products not be exceeded.
