Treating high blood pressure alone or with other medicines. It may also be used for other conditions as determined by your doctor.
Quinapril is an angiotensin-converting enzyme (ACE) inhibitor. It works by relaxing blood vessels. This helps to lower blood pressure.
Do NOT use quinapril if:
- you are allergic to any ingredient in quinapril
- you are pregnant
- you have a history of angioedema (swelling of the hands, face, lips, eyes, throat, or tongue; difficulty swallowing or breathing; or unusual hoarseness), including angioedema caused by treatment with an ACE inhibitor
- you are also taking aliskiren and you have either diabetes or kidney problems
Contact your doctor or health care provider right away if any of these apply to you.

- Insulin, sulfonylureas (eg, glipizide), or other oral diabetes medicines (eg, metformin) because the risk of low blood sugar may be increased
- Certain gold-containing medicines (eg, auranofin, sodium aurothiomalate) because flushing, nausea, vomiting, and low blood pressure may occur
- Nonsteroidal anti-inflammatory drugs (NSAIDs) (eg, ibuprofen, indomethacin, celecoxib) because they may decrease quinapril's effectiveness and the risk of kidney problems may be increased

How to use quinapril:
Use quinapril as directed by your doctor. Check the label on the medicine for exact dosing instructions.
- If you are taking a tetracycline antibiotic (eg, doxycycline) or a fluoroquinolone antibiotic (eg, ciprofloxacin), ask your doctor or pharmacist how to take it with quinapril. This product contains magnesium, which can interfere with absorption of these antibiotics.
- Quinapril works best if it is taken at the same time each day. Taking quinapril at the same time each day will help you remember to take it.
- Continue to use quinapril even if you feel well. Do not miss any doses.
- If you miss a dose of quinapril, take it as soon as possible. If it is almost time for your next dose, skip the missed dose and go back to your regular dosing schedule. Do not take 2 doses at once.

Important safety information:
- Quinapril may cause dizziness, light-headedness, or fainting. These effects may be worse if you take it with alcohol or certain medicines. Use quinapril with caution. Do not drive or perform other possibly unsafe tasks until you know how you react to it.
- Quinapril may cause dizziness, light-headedness, or fainting; alcohol, hot weather, exercise, or fever may increase these effects. To prevent them, sit up or stand slowly, especially in the morning. Sit or lie down at the first sign of any of these effects.
- Quinapril may cause a serious side effect called angioedema. The risk may be higher in black patients. Contact your doctor at once if you develop swelling of the hands, face, lips, eyes, throat, or tongue; difficulty swallowing or breathing; or unusual hoarseness.
- Patients who take medicine for high blood pressure often feel tired or run down for a few weeks after starting treatment. Be sure to take your medicine even if you may not feel "normal." Tell your doctor if you develop any new symptoms.

- Dehydration, excessive sweating, vomiting, or diarrhea may increase the risk of low blood pressure. Contact your health care provider at once if any of these occur.
