Directions of use

The recommended adult dose of finasteride is 5 mg once daily, taken with or without food.

Many things can affect the dose of a medication that a person needs, such as body weight, other medical conditions, and other medications. If your doctor has recommended a dose different from the ones listed here, do not change the way that you are taking the medication without consulting your doctor.

It is important to take Finasteride exactly as prescribed by your doctor. If you miss a dose, skip the missed dose and continue with your regular dosing schedule. Do not take a double dose to make up for a missed one. If you are not sure what to do after missing a dose, contact your doctor or pharmacist for advice.

Store Finasteride at room temperature. Protect it from light and keep it out of the reach of children. Women who are or may become pregnant should not handle crushed or broken tablets of Finasteride.

Do not dispose of medications in wastewater (e.g. down the sink or in the toilet) or in household garbage. Ask your pharmacist how to dispose of medications that are no longer needed or have expired.

Before you begin using a medication, be sure to inform your doctor of any medical conditions or Allergies you may have, any medications you are taking, whether you are pregnant or breast-feeding, and any other significant facts about your health. These factors may affect how you should use Finasteride.

Breast Cancer: Male breast cancer has been reported in a small number of people taking finasteride. It is not known with certainty whether finasteride can cause breast cancer, but this possibility cannot be ruled out at this time. If you notice any changes in your breasts, such as breast enlargement, pain, tenderness, lumps, or nipple discharge, contact your doctor as soon as possible.

Laboratory tests: Finasteride may decrease PSA levels (a substance normally produced and used to evaluate Prostate Cancer) and should be taken into account when evaluating PSA levels.

Liver function: Liver disease or reduced liver function may cause Finasteride to build up in the body, causing side effects. If you have liver problems, discuss with your doctor how Finasteride may affect your medical condition, how your medical condition may affect the dosing and effectiveness of Finasteride, and whether any special monitoring is needed.

Long-term use: The effects of using Finasteride for the long term (i.e., more than 10 years) have not been established.

Prostate cancer: Finasteride (for BPH) may be linked with an increased risk of developing a rare type of cancer called high-grade prostate cancer. The risk of this cancer while taking Finasteride is still considered very small. Note that finasteride (for BPH) is not approved to treat prostate cancer. If you have any concerns about Finasteride, talk to your health care provider.

Surgery: People who are candidates for immediate prostate surgery should not take finasteride.

Pregnancy and birth defects: When absorbed into the system of a pregnant woman, finasteride may cause abnormalities of the genitals in a male baby. Crushed or broken finasteride tablets should not be handled by women who are or may become pregnant because finasteride may be absorbed into their system through the skin.

Children: Finasteride should not be used by children.
