Captopril is a type of prescription medication known as an angiotensin converting enzyme inhibitor, also referred to as an ACE inhibitor, and is typically used to treat heart disease, high blood pressure, and to help prevent kidney failure. Some of the most common Captopril side effects include coughing, a noticeable decrease in the ability to taste, and the development of a skin rash. Other frequently reported side effects include itching, heart palpitations, and headaches. Some patients taking this medication may have a decrease in infection-fighting white blood cells or may have protein in the urine. Any questions or concerns about potential Captopril side effects should be discussed with a doctor or other medical professional.
Most of the potential Captopril side effects are mild and do not affect the patient's ability to take this medication, although any persistent or bothersome symptoms should be reported to a doctor for further evaluation. Symptoms such as headache, dizziness, or nausea often go away after taking the medication for a few days. A low-grade fever or the development of a mild cough are common when taking this drug. Gastrointestinal disturbances such as nausea or vomiting may be eased by taking the medication with food or milk. These symptoms usually go away completely after discontinuing the medication.
Mild cardiac symptoms are relatively common Captopril side effects. Heart palpitations, or a feeling that the heart is racing, is the most frequently reported of these symptoms. This symptom is most common immediately following physical exertion and often goes away when the patient lies down. If chest pain develops or if the heartbeat is consistently more rapid than normal, the doctor should be notified. These symptoms may indicate the presence of a serious complication and could require emergency treatment, especially in patients who already have a history of heart-related problems.
Severe allergic reactions may occur as Captopril side effects, even if the patient has successfully taken this medication in the past with no negative side effects. This type of potentially fatal allergic reaction is known as anaphylaxis and requires immediate medical attention. Symptoms of anaphylaxis may include the development of a rash or hives and swelling, especially involving the face, tongue, and throat. Breathing may become difficult or impossible, and the patient may lose partial or complete consciousness. Emergency medical attention is required for this side effect, and life-support measures are frequently needed in order to save the life of the patient.
