What is the most important information I should know about captopril (Capoten)?

Do not use captopril if you are pregnant. Captopril can cause injury or death to the unborn baby if you take the medicine during your second or third trimester.

You should not use this medication if you are allergic to captopril or to any other ACE inhibitor, such as benazepril (Lotensin), fosinopril (Monopril), enalapril (Vasotec), lisinopril (Prinivil, Zestril), moexipril (Univasc), perindopril (Aceon), quinapril (Accupril), ramipril (Altace), or trandolapril (Mavik).

If you have kidney disease or diabetes, you should not take captopril if you are also taking aliskiren (Tekturna, Tekamlo, Valturna, Amturnide).

Drinking alcohol can further lower your blood pressure and may increase certain side effects of captopril.

Do not use salt substitutes or potassium supplements while taking captopril, unless your doctor has told you to.

Conditions that may cause very low blood pressure include: vomiting, diarrhea, heavy sweating, heart disease, dialysis, a low salt diet, or taking diuretics (water pills). Follow your doctor's instructions about the type and amount of liquids you should drink while taking captopril. Tell your doctor if you have a prolonged illness that causes diarrhea or vomiting.
