Uses
This medication is used to treat men with prostate cancer. Flutamide belongs to a class of drugs known as anti-androgens (anti-testosterone). Testosterone, a natural hormone, helps prostate cancer to grow and spread. Flutamide works by blocking the effects of testosterone, thereby slowing the growth and spread of prostate cancer.
How to use Eulexin 125 Mg Capsule Antiandrogen
Read the Patient Information Leaflet if available from your pharmacist before you start using flutamide and each time you get a refill. If you have any questions, ask your doctor or pharmacist.
Take this medication by mouth with or without food as directed by your doctor, usually 3 times daily.
The dosage is based on your medical condition and response to treatment.
Use this medication regularly to get the most benefit from it. To help you remember, take it at the same times each day. Do not stop any medications for your prostate cancer unless told to do so by your doctor. Stopping your medications could allow the cancer to spread more rapidly.
Tell your doctor if your condition lasts or gets worse (such as urination becomes more difficult, bone pain increases).
Side Effects
See also Warning section.
Because flutamide is usually used with other medications, the side effects may be caused by the other medications or their combination. Hot flashes, loss of sexual interest/ability, diarrhea, nausea, vomiting, and enlargement of male breasts may occur. Less common side effects include drowsiness. If any of these effects last or get worse, tell your doctor or pharmacist promptly.
Diarrhea is a common side effect. Drink plenty of fluids as directed by your doctor to reduce your risk of dehydration. You may decrease dairy products, increase whole grains/vegetables/fruit, and stop any laxatives. Your doctor may prescribe anti-diarrhea medication (such as loperamide) to control your symptoms. Tell your doctor right away if you develop diarrhea that is severe or doesn't stop, or signs of dehydration (such as dizziness, decreased urination).
Flutamide may change the color of your urine to light orange-brown or yellow-green. This is not harmful.
Remember that this medication has been prescribed because your doctor has judged that the benefit to you is greater than the risk of side effects. Many people using this medication do not have serious side effects.
