What is finasteride (Proscar)? How does it work (mechanism of action)?
The prostate gland is located around the tube which empties urine from the bladder (urethra). As the prostate gland enlarges, usually after 50 years of age, it can obstruct or partially block the urine flow. This leads to symptoms which include dribbling of urine, narrow stream, problems starting urine flow, interruption while urinating, and a feeling of incomplete emptying. Other symptoms include wetting and staining of clothes, urinary burning, and urgency.
Prostate gland enlargement (benign prostatic hyperplasia or BPH), is directly dependent on DHT (a hormone converted from the male hormone testosterone). Finasteride inhibits the enzyme necessary for the conversion of testosterone to DHT in the prostate. Therefore, administration of finasteride lowers blood and tissue DHT levels and helps reduce the size of the prostate gland.
Although reductions in the size of the prostate gland can occur in virtually all the patients who take finasteride, only 50% will experience improvement in the symptoms of BPH. Patients generally respond to finasteride in several weeks, but it often takes 6 months for the patient to receive the full effect of the drug.
What are the uses for finasteride?
Finasteride is prescribed for the treatment of enlarged prostate (benign prostatic hyperplasia, BPH) under the brand name "Proscar." Finasteride also is prescribed to treat male pattern baldness in androgenetic alopecia in males only, under the brand name Propecia.
What are the side effects of finasteride?
Side effects are rare but can include impotence and decreased sex drive. Finasteride should not be used by women, children, or male partners of women trying to become pregnant. Finasteride should not be used until a thorough prostate examination has been done to exclude cancer, stricture, or infection in the gland. Rarely, cases of male breast cancer have been reported.
What is the dosage for finasteride?
Finasteride is metabolized mainly by the liver, and caution should be used in patients with liver dysfunction. Finasteride may be taken with or without food.
Which drugs or supplements interact with finasteride?
Drug interactions are generally not a problem.
Is finasteride safe to take if I'm pregnant or breastfeeding?
Finasteride causes abnormal development of the sexual organs of the male fetus. Therefore, women who are pregnant or are likely to be pregnant should not handle crushed or broken finasteride tablets in order to prevent absorption through the skin.
Finasteride is not prescribed for women.
What else should I know about finasteride?
What preparations of finasteride are available?
Tablet (5mg).
How should I keep finasteride stored?
Finasteride should be stored at room temperature in a tight, light resistant container.
Finasteride is available in generic form, but you must have a prescription from your doctor or other health-care professional to obtain the drug.
Summary
Finasteride (Proscar) is a drug prescribed for the treatment of prostate gland enlargement (benign prostatic hyperplasia or BPH). Side effects, drug interactions, pregnancy information, dosing, and patient information should be reviewed prior to taking any medication.

Benign Prostatic Hyperplasia
Benign prostatic hyperplasia (BPH or enlarged prostate) is very common in men over 50 years of age. Half of all men over the age of 50 develop symptoms of BPH, but few need medical treatment. This noncancerous enlargement of the prostate can impede urine flow, slow the flow of urine, create the urge to urinate frequently and cause other symptoms like complete blockage of urine and urinary tract infections. More serious symptoms are urinary tract infections (UTIs) and complete blockage of the urethra, which may be a medical emergency.
BPH is not cancer. Not all men with the condition need treatment, and usually is closely monitored if no symptoms are present. Treatment measures usually are reserved for men with significant symptoms, and can include medications, surgery, microwave therapy, and laser procedures. Men can prevent prostate problems by having regular medical checkups that include a prostate exam. Contact your doctor or other medical professional if you have these symptoms:
- Painful urination
- Blood in the urine
- Difficult urinating
- A frequent urge to urinate
- Dribbling of urine
Cancer Prevention
Certain behavioral, lifestyle, and environmental factors contribute to cancer. Cancer prevention involves modifying these factors to decrease cancer risk. Tobacco use, alcohol consumption, physical inactivity, inadequate fruit and vegetable intake, and obesity increase the risk of certain cancers. Vaccines, genetic testing, and cancer screening also play a role in cancer prevention.doxazosin mesylate
Doxazosin mesylate (Cardura, Cardura XL) is a medication prescribed for the treatment of high blood pressure and the symptoms of benign prostatic hyperplasia (BPH, enlarged prostate gland). Side effects, drug interactions, warnings and precautions, and patient safety information should be reviewed prior to taking any medication.Drug Interactions
Drug interactions occur frequently.

Important information about your drugs should be reviewed prior to taking any prescription drug. Side effects, drug interactions, warnings and precauctions, dosage, what the drug is used for, what to do if you miss a dose, how the drug is to be stored, and generic vs. brand names.Dutasteride vs. Finasteride
Dutasteride (brand name Avodart) and finasteride (brand name Procar) are medications prescribed for the treatment of an enlarged prostate (benign prostatic hyperplasia, BPH). Both dutasteride and finasteride delay the progression of an enlarged prostate gland, which improves symptoms of BPH.
The side effects of both drugs are mostly sexual problems like breast enlargement, impotence (erectile dysfunction, ED). However, dutasteride may cause allergic reactions, and increases the risk of high-grade prostate cancer. In rare cases, finasteride has caused male breast cancer.
The recommended dose for dutasteride is 0.5 mg once daily. finasteride should be used with caution if you have liver dysfunction. Neither drug should be used in females or pediatric patients.Take the BPH Quiz
