Consumer Medicine Information


This leaflet answers some common questions about Captopril Sandoz.

It does not contain all the available information. It does not take the place of talking to your doctor or pharmacist.

All medicines have risks and benefits. Your doctor has weighed the risks of you taking this medicine against the benefits they expect it will have for you.

If you have any concerns about taking this medicine, ask your doctor or pharmacist.

Keep this leaflet with the medicine. You may need to read it again.


This medicine is used to treat:

  • high blood pressure (hypertension)
  • certain heart conditions
  • certain kidney conditions associated with diabetes.

It contains the active ingredient captopril.

Captopril belongs to a group of medicines called angiotensin converting enzymes (ACE) inhibitors.

It works by widening your blood vessels, which reduces pressure in the vessels. This makes it easier for your heart to pump blood around your body, and helps your kidneys work better.

Ask your doctor if you have any questions about why this medicine has been prescribed for you. Your doctor may have prescribed it for another reason.

This medicine is not addictive.

This medicine is available only with a doctor's prescription.

  • captopril, the active ingredient, or to any of the other ingredients listed at the end of this leaflet under Product Description.
  • any other similar medicines such as ACE inhibitors. Examples include perindopril (Coversyl®), ramipril (Tritace®) and enalapril (Renitec®).

Some of the symptoms of an allergic reaction may include:

  • shortness of breath
  • wheezing or difficulty breathing
  • swelling of the face, lips, tongue or other parts of the body
