Prehist

Main Ingredients: Chlorpheniramine Maleate + Phenylephrine Hydrochloride

Prehist is the combination of antihistamine and decongestant (pseudoephedrine) given to treat and relieve symptoms of seasonal allergies, common cold and flu as well as upper respiratory tract.

The antihistamine in Prehist relieves the symptoms of seasonal allergies and hay fever such as itchy, runny nose, sneezing, and watery eyes as well as symptoms of allergic reactions like hives or swelling. The decongestant (pseudoephedrine) in Prehist deals with constricting the blood vessels, which in turn reduces the blood, flow to the nasal passages thereby improving the flow of air and reducing nasal secretions.

CAUTION

Use caution when using Prehist if you have high blood pressure, diabetes, heart disease, prostate problems, or hyperthyroidism as it contains the decongestant pseudoephedrine.

Avoid Prehist if you have severe high blood pressure, glaucoma, or kidney disease.

Avoid taking Prehist within 2 weeks of using an MAO-inhibitor.

Avoid Prehist if you are allergic or sensitive to it.

May cause drowsiness or low concentration. Use caution when driving or operating machinery.
