Before taking this medicine
You should not use this medicine if you are allergic to fosinopril or similar medications, such as benazepril, captopril, enalapril, lisinopril, moexipril, perindopril, quinapril, ramipril, or trandolapril.
If you have diabetes, do not use fosinopril together with any medication that contains aliskiren (such as Amturnide, Tekturna, Tekamlo).
You may also need to avoid taking fosinopril with aliskiren if you have kidney disease.
To make sure fosinopril is safe for you, tell your doctor if you have:
kidney disease (or if you are on dialysis);
if you are on a low-salt diet; or
if you have ever had a severe allergic reaction.
Do not use if you are pregnant. If you become pregnant, stop taking this medicine and tell your doctor right away. Fosinopril can cause injury or death to the unborn baby if you take the medicine during your second or third trimester.
Fosinopril can pass into breast milk and may harm a nursing baby. You should not breast-feed while using this medicine.
Do not give this medication to a child younger than 6 years old.
How should I take fosinopril?
Follow all directions on your prescription label. Your doctor may occasionally change your dose. Do not use this medicine in larger or smaller amounts or for longer than recommended.
Fosinopril can be taken with or without food.
Call your doctor if you have ongoing vomiting or diarrhea, or if you are sweating more than usual. You can easily become dehydrated while taking fosinopril. This can lead to very low blood pressure, electrolyte disorders, or kidney failure.
While using fosinopril, you may need frequent blood tests at your doctor's office. Your blood pressure will need to be checked often.
If you need surgery or medical tests, tell the doctor ahead of time that you are using fosinopril. You may need to stop using the medicine for a short time.
If you are being treated for high blood pressure, keep using this medication even if you feel well. High blood pressure often has no symptoms. You may need to use blood pressure medication for the rest of your life.
Store at room temperature away from moisture and heat.
What happens if I miss a dose?
Take the missed dose as soon as you remember. Skip the missed dose if it is almost time for your next scheduled dose. Do not take extra medicine to make up the missed dose.
What happens if I overdose?
Seek emergency medical attention or call the Poison Help line at 1-800-222-1222.
What should I avoid while taking fosinopril?
Avoid drinking alcohol. It can further lower your blood pressure and may increase some of the side effects of fosinopril.
Avoid taking an antacid within 2 hours before or after you take fosinopril.
Do not use salt substitutes or potassium supplements while taking fosinopril, unless your doctor has told you to.
Avoid getting up too fast from a sitting or lying position, or you may feel dizzy. Get up slowly and steady yourself to prevent a fall.

sudden weakness or ill feeling, fever, chills, sore throat, painful mouth sores, cough, trouble breathing;
