Histex: Uses, Dosage, Demographic, Side Effects, Interactions, Generic Options Histex is an over-the-counter medication used to relieve symptoms related to allergies, such as runny nose, sneezing, and watery eyes. Histex is a type of antihistamine medication and works by blocking the effects of a natural chemical called histamine, which is produced by the body's immune system when it detects an allergen. Uses and Dosage: Histex is primarily used to treat symptoms associated with allergies, including hay fever, hives, and other allergic reactions. The recommended dosage for Histex varies depending on the age of the patient. For adults and children over the age of 12, a typical dose is one to two tablets every four to six hours, not to exceed six tablets in a 24-hour period. For children aged six to 12, the dosage is half a tablet every four to six hours, not to exceed three tablets in a 24-hour period. Demographic: Histex is generally safe and effective for most people, but there may be some exceptions. Patients who have certain medical conditions or are taking certain medications may not be able to take Histex. For example, patients who have liver or kidney disease, glaucoma, or enlarged prostate may be at risk for complications if they take Histex. Pregnant or breastfeeding women should also consult with their healthcare provider before taking any antihistamine medication.

Generic versions of antihistamines like Histex are typically less expensive than their brand name counterparts, but patients should always consult with their healthcare provider before switching medications.
