Propecia (Finasteride)(℞) Prescription Required
Propecia (Finasteride) Dosage and Side Effects
PROPECIA is used for the treatment of male pattern hair loss (also known as androgenetic alopecia).
Proper Use of this medication
Take one tablet of PROPECIA every day, with or without food.
In case of drug overdose, contact a health care practitioner, hospital emergency department or regional Poison Control Centre immediately, even if there are no symptoms.
If you miss a dose, do not take an extra one. Just take the next tablet as usual.
When can I expect to see results from using PROPECIA?
Male pattern hair loss is a condition that develops over a long period of time. On average, healthy hair grows only about 1 cm each month. Therefore, it will take time to see any effect. In general, daily use for three months or more may be necessary before you notice that hair growth is increased or further hair loss is prevented.
How long do I need to use PROPECIA?
PROPECIA can only work over the long term if you continue taking it.
Common side effects:
- less desire to have sex;
- difficulty in achieving an erection;
- problems with ejaculation, such as a decrease in the amount of semen released during sex (this does not appear to interfere with normal sexual function).
In clinical studies, these side effects disappeared in men who stopped taking PROPECIA and in most men who continued treatment.
In general use, the following have been reported infrequently:
- breast enlargement (swelling) and/or tenderness;
- decrease in sex drive that continued after stopping the medication;
- allergic reactions including rash, itching, hives, and swelling of the lips, tongue, throat and face;
- problems with ejaculation that continued after stopping the medication;
- testicular pain;
- difficulty in achieving an erection that continued after stopping the medication;
- male infertility and/or poor quality of semen. Improvement in the quality of semen has been reported after stopping the medication;
- male breast cancer.
Talk to your doctor about any changes in your breast such as lumps, pain or nipple discharge. Tell your physician or pharmacist promptly about these or any other unusual symptoms.
Warnings and Precautions
BEFORE you use PROPECIA talk to your physician or pharmacist about any medical problems you have or have had, especially liver disease, and about any allergies.
PROSCAR (finasteride at 5 times the dose of PROPECIA) may increase the chance of a more serious form of prostate cancer.
Women who are or may potentially be pregnant must not use PROPECIA. They should also not handle crushed or broken tablets of PROPECIA. If the active ingredient in PROPECIA is absorbed after oral use or through the skin by a woman who is pregnant with a male baby, it may cause the male baby to be born with abnormalities of the sex organs. 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 who is pregnant comes into contact with the active ingredient in PROPECIA, a physician should be consulted.
Interactions with this medication
PROPECIA usually does not interfere with other medicines. However, you should always tell your physician about all medicines you are taking or plan to take, including those obtained without prescription.
PROPECIA can affect a blood test called PSA (prostate-specific antigen) used for the screening of prostate cancer. If you have a PSA test done, you should tell your physician that you are taking PROPECIA.
