Finasteride

What It's For & How To Take

Finasteride is used in men to treat an enlarged prostate not caused by cancer. This condition is called benign prostatic hypertrophy or BPH for short. Finasteride is used by itself or along with other medications to reduce urinary symptoms related to the prostate. This medication allows the prostate to slow its growth and possibly shrink in size.

As men age, the prostate slowly grows. This may cause uncomfortable urinary symptoms. These symptoms include urinating often, feeling like you need to urinate all the time, getting up many times at night to urinate, and a difficult time starting a urine stream.

Finasteride will help relax the muscles in your prostate and the opening of your bladder. This may help your urine flow more easily. Your prostate will continue to grow, and over time this medication may not work as well.

This medication is sometimes used to treat other conditions. Talk with your doctor or pharmacist if you are prescribed this medication to treat something that is not listed here.

Finasteride is usually taken once daily, with or without food. Swallow the tablet whole. Do not crush or chew the tablet. It may take up to 6 months before you notice a positive effect from this medication. If your condition does not begin to get any better, or worsens, notify your doctor.

If you miss a dose, take it as soon as you remember. If it is near the time of your next dose, skip it and continue with your normal dose time. Do not take a double dose to make up the missed dose.
