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

What is captopril?
Captopril is in a group of drugs called ACE inhibitors. ACE stands for angiotensin converting enzyme.
Captopril is used to treat high blood pressure (hypertension), congestive heart failure, kidney problems caused by diabetes, and to improve survival after a heart attack.
Captopril may also be used for purposes other than those listed in this medication guide.
What should I discuss with my healthcare provider before taking captopril?
Do not use this medication if you are allergic to captopril or to any other ACE inhibitor, such as benazopril (Lotensin), fosinopril (Monopril), enalapril (Vasotec), lisinopril (Prinivil, Zestril), moexipril (Univasc), perindopril (Aceon), quinapril (Accupril), ramipril (Altace), or trandolapril (Mavik).Before using captopril, tell your doctor if you are allergic to any drugs, or if you have:
-
kidney disease (or if you are on dialysis);
-
heart disease or congestive heart failure;
-
diabetes; or
-
a connective tissue disease such as Marfan syndrome, Sjogren's syndrome, lupus, scleroderma, or rheumatoid arthritis.
If you have any of these conditions, you may not be able to use captopril, or you may need a dosage adjustment or special tests during treatment.
