Hydrochlorothiazide-quinapril Oral Tablet

Name: Hydrochlorothiazide-quinapril Oral Tablet

Highlights for hydrochlorothiazide-quinapril

Quinapril/hydrochlorothiazide is a combination of two medications in a single form that work in different ways to treat hypertension (high blood pressure). Lowering your blood pressure will reduce your chance of having a stroke or heart attack.

This drug shouldn’t be the first medication you take to treat high blood pressure. If your blood pressure isn’t controlled with quinapril or hydrochlorothiazide alone, you can try this combination tablet.

You shouldn’t take this drug if you’re pregnant or plan to become pregnant. It can harm or be fatal to your unborn baby.

The standard starting dose is 10 mg quinapril/12.5 mg hydrochlorothiazide or 20 mg quinapril/12.5 mg hydrochlorothiazide taken by mouth once per day. If your blood pressure is still high after 2–3 weeks, your doctor may increase your dose.

Common side effects include cough, headache, dizziness, tiredness, nausea, vomiting, diarrhea, stomach pain, and dry mouth.
