Abiraterone is a steroidal inhibitor and androgen synthesis inhibitor used in the treatment of certain types of prostate cancer. Some prostate cancer does not respond to typical androgen deprivation treatment or androgen receptor antagonists, so Abiraterone is used in these cases.
Like any medication, Abiraterone can have unwanted physical effects on a patient, in addition to the desired medical effects. Some of these side effects may be grounds for you to discontinue using Abiraterone, or to add other aspects to your health care plan to deal with these effects. While not all side effects are dangerous or life-threatening, all side effects should be reported to your physician or medical care provider.
Some side effects of Abiraterone are unpleasant, but not necessarily life-threatening or a sign of a larger medical problem. These side effects are usually due to your body adjusting to the medication, and may subside over the course of treatment as you get used to the new substance. All side effects of Abiraterone should be reported to your doctor, especially if they become bothersome. Your doctor may be able to prescribe a course of treatment that will help you negate the symptoms of these side effects.
While taking Abiraterone, you may experience mild gastrointestinal symptoms such as an upset or acid stomach, heartburn, or indigestion, sometimes accomanied by excessive belching. You may experience effects on your muscular system, such as joint pain, swelling or stiffness in the joints, muscle cramps or spasms, aches or pain in the muscle or bone, muscle stiffness, or difficulty in moving. You may also experience cold-like symptoms, such as nasal congestion or a runny nose, coughing and sneezing, mild chills, ear congestion, sore throat, or laryngitis.
Abiraterone may cause more serious side effects in some patients, which can be signs of dangerous health problems, or cause major health problems in and of themselves. If you experience these symptoms while taking Abiraterone, contact your physician or seek medical care immediately. These symptoms may be signs of serious health problems, such as kidney or liver malfunction, hypertension or hypotension, or an allergic reaction.
You may experience problems associated with urinary disorders, such as lower side or back pain, bladder pain, increased thirst or dry mouth, an increased or unusually frequent urge to urinate, less urine production than usual, pain or burning while urinating or associated with urinating, difficulty urinating, or urine that is bloody, cloudy, or dark.
You may also experience stomach or abdominal pain or tenderness around that area, decreased appetite or loss of appetite, nausea or nausea to the point of vomiting, rapid weight gain or sudden loss of weight, diarrhea, or clay-colored stools. You may experience severe muscle pain or cramps, headaches, pain or swelling in the legs without any injury, pain in the jaw, back or arms, swelling or bloating of the extremities, such as arms, hands and fingers, legs, feet and face, or swelling with depressions or pits in the skin.
Seek medical attention immediately if you experience respiratory problems, such as chest pain or chest discomfort, heaviness or tightness in the chest, wheezing, difficulty breathing or irregular breathing, dizziness, lightheadedness or fainting, numbness or tingling in the extremities, such as hands, feet or lips, shortness of breath or an unusually slow, fast or irregular heartbeat or pulse.
Additionally, contact a doctor if you experience a sudden redness or the face, arms, neck, or upper chest, unusually cool and sweaty skin or sudden sweating, a feeling of unusual warmth or fever, extreme fatigue, physical weakness, or dilated neck veins.

If any of these symptoms occur, contact your doctor immediately and seek medical assistance.

Seek medical attention immediately if you experience signs of hypertension, such as vertigo or lightheadedness, ringing or buzzing in the ears, or blurred vision. Get medical help immediately if you experience signs of hypokalemia, such as unusual muscle weakness, muscle tremors or muscle cramps, accompanied by constipation.
