Why is this medication prescribed?

Alahist LQ is a combination medication that contains diphenhydramine and phenylephrine. Here’s what these ingredients do:

• Diphenhydramine is an antihistamine that helps relieve allergy symptoms like sneezing, runny nose, and itching by blocking histamine, a substance in the body that causes these symptoms.
• Phenylephrine is a decongestant that works by shrinking the blood vessels in the nasal passages, which helps reduce nasal congestion.

Alahist LQ is often prescribed to treat symptoms associated with allergies or the common cold, such as:

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

How should this medicine be used?

Here are some general guidelines for using Alahist LQ:

• Dosage: Follow the dosage instructions provided by your healthcare provider or on the medication label. Typically, this medication is taken orally in liquid form.

• Frequency: The usual dosage may be taken every 4 to 6 hours as needed, but you should not exceed the recommended dose.
• Food/Drink: You can take this medication with or without food.

• Other Medications: Inform your healthcare provider about any other medications you are taking, as diphenhydramine can interact with various drugs.
