Why is this medication prescribed?

Alahist LQ is a combination medication that contains diphenhydramine and phenylephrine. It’s typically prescribed for the relief of symptoms associated with allergies and the common cold, such as:

• Nasal congestion
• Runny nose
• Sneezing
• Itchy or watery eyes

Diphenhydramine is an antihistamine that helps reduce allergy symptoms by blocking histamine, a substance in the body that causes allergic reactions. Phenylephrine is a decongestant that works by narrowing the blood vessels in the nasal passages, which helps to reduce congestion.
