All About Propecia

Get emergency medical help if you have any of these signs of an allergic reaction: hives; difficulty breathing; swelling of your face, lips, tongue, or throat. Call your doctor at once if you notice any breast lumps, pain, nipple discharge, or other breast changes. These may be signs of male breast cancer.

Less serious side effects may include:

• feeling like you might pass out;
• swelling in your hands or feet;
• pain in the testicles;
• impotence, loss of interest in sex, or trouble having an orgasm;
• abnormal ejaculation;
• swelling or tenderness in your breasts;
• dizziness, weakness;
• headache;
• runny nose; or
• skin rash.

This is not a complete list of side effects and others may occur. Tell your doctor about any unusual or bothersome side effect.

What happens if I miss a dose?

Take the missed dose as soon as you remember. If it is almost time for your next dose, wait until then to take the medicine and skip the missed dose. Do not take extra medicine to make up the missed dose.

What happens if I overdose?

Seek emergency medical attention if you think you have used too much of this medicine. An overdose of Propecia is not expected to produce life-threatening symptoms.

Before taking Propecia, tell your doctor if you have ever had an allergic reaction to this medication, or to a similar medicine called dutasteride (Avodart). Also tell your doctor if you have:

Propecia should never be taken by a woman or a child. Finasteride can be absorbed through the skin, and women or children should not be permitted to handle Propecia tablets. Although Propecia is not for use by women, this medication can cause birth defects if a woman is exposed to it during pregnancy. Propecia tablets should not be handled by a woman who is pregnant or who may become pregnant. Propecia tablets are coated and will prevent contact with the active ingredient during normal handling, provided that the tablets are not broken or crushed. If a woman accidentally comes into contact with this medication from a broken or crushed tablet, wash the area with soap and water right away.
