Why is this medication prescribed?

RhinaHist is a combination medication that typically contains two active ingredients: chlorpheniramine and phenylephrine. It is commonly prescribed for the relief of symptoms associated with seasonal allergies, such as sneezing, itching, watery eyes, and nasal congestion.

Chlorpheniramine is an antihistamine that helps alleviate symptoms caused by the release of histamine in the body in response to allergens. It can reduce or block the effects of histamine, which include itching, sneezing, and a runny nose.

Phenylephrine is a decongestant that works by narrowing the blood vessels in the nasal passages, helping to relieve congestion.

RhinaHist is often used to manage symptoms related to hay fever (allergic rhinitis), as well as other respiratory conditions that involve nasal congestion and allergic reactions. It’s important to use this medication as directed by a healthcare professional, as misuse or overuse may lead to side effects or complications. Always consult with your doctor or pharmacist regarding any questions or concerns about your medications.
