Overview Information on Propecia
Pharmacist Tip
Take Propecia with a full glass of water.     
Propecia® is a brand name for finasteride, a prescription medicine used to treat hair loss in men, also called male pattern baldness. Propecia works by blocking a hormone in the scalp. When this happens, Propecia helps to regrow hair that has been lost and to prevent further hair loss.

Propecia is only approved for use in men and should not be taken by women or children. Women who are pregnant or who may become pregnant should not touch, handle, or come into contact with Propecia tablets. Propecia can be absorbed through skin and cause birth defects in a male baby's sex organs. Unbroken Propecia tablets are coated, but they become dangerous if they are broken or crushed. Pregnant women should wash their hands with soap and water and call their doctor right away if they have had direct contact with Propecia tablets.

Finasteride is also sold under the brand name Proscar®. Proscar is given to men to treat benign prostatic hyperplasia (BPH), which is also known as enlarged prostate.

If you are taking Propecia, take it exactly as your doctor tells you to take it. You may take Propecia with or without food. Take Propecia at the same time every day. If you forget to take Propecia, do not take an extra tablet. Just take the next tablet according to your regular schedule. Taking extra doses of Propecia will not make hair grow faster or better.

It can take months before you notice the full effects of Propecia. Men who take Propecia see some hair regrowth or hair that has stopped falling out within three months or more.

Propecia is not a cure for hair loss. If you stop taking Propecia, the hair that has regrown will likely be lost again.

Before taking Propecia, your doctor will want to make sure that Propecia is the right medicine for you to take. Talk with your doctor about any other medical conditions that you have. Your doctor may specifically want to know about:
  • Liver problems
  • Prostate cancer
  • Allergic reactions to any medicines
Tell your doctor about any other medicines you take before taking Propecia. Include over-the-counter medicines, herbal remedies, vitamins, and supplements.

There are some other risks that you should know about when taking Propecia. Men who take Propecia may have an increased risk for developing prostate cancer. Propecia can also interfere with screening tests for this disease. Talk with your doctor if you are concerned about this risk factor.

Propecia may also cause changes to breast tissue. You may notice tenderness, lumpiness, or enlargement of breast tissue or nipple. Be sure to report these symptoms to your doctor.

Some patients taking Propecia also report side effects such as:
  • Change in sex drive
  • Problems with ejaculation or having erections
  • Decrease in amount and quality of semen
This is not a complete list of all the side effects or risks of taking Propecia. Talk with your doctor about these and other side effects. Some sexual side effects may continue even after you stop taking Propecia, so it is important to notify your doctor as soon as they occur.

While you are taking Propecia, be aware of more serious side effects. Tell your doctor right away if you experience signs of an allergic reaction, which can include itching or hives, swelling in your face or hands, swelling or tingling in your mouth or throat, trouble breathing or swallowing, and chest pain.

Call your doctor if you are taking Propecia and develop side effects such as:
  • Breast swelling, pain, or tenderness
  • Breast lumps or pain
  • Nipple discharge
  • Testicular pain
