About Finasteride 5 mg

  • Reduces the enlarged prostate.
  • Improves urine flow and other symptoms of BPH.
  • Reduces the risk of suddenly being unable to urinate (acute urinary retention).
  • Reduces the chance of having to undergo surgery.

Finasteride 5 mg is intended for use in men only.

If you take more Finasteride than you should, or if a child has taken this medicine by accident, please notify your doctor or pharmacist immediately.

If you forget to take a dose of Finasteride, you can take it as soon as you remember unless it is almost time for the next dose, in which case you should continue with your medication as prescribed. Never take a double dose to make up for the forgotten one.

When not to use Finasteride 5 mg

Finasteride 5 mg is not suitable for everyone. Do not take this medicine if:

  • You are allergic to the active ingredient or to any of the other ingredients in this medicine which are listed at the end of this leaflet under 'What Finasteride contains'.
  • You are a woman or child (see section 'Pregnancy and breastfeeding').

When should this medicine be used with extreme caution?

Talk to your doctor or pharmacist before taking Finasteride 5 mg if:

  • Your sexual partner is or may potentially be pregnant, in which case you should avoid exposing her to your semen (by using a condom). Your semen could contain a tiny amount of the medicine and may affect the normal development of the baby’s sex organs.
  • You are having a PSA test. This medicine may affect the results of PSA (prostate-specific antigen) tests.
  • You have a large amount of residual urine and/or severely reduced urinary flow. If this is the case, you should be closely monitored for narrowing of the urinary tract.

You should promptly report to your doctor any changes in your breast tissue such as lumps, pain, enlargement or nipple discharge as these may be signs of a serious condition, such as breast cancer.

Pregnancy and breastfeeding

Finasteride should not be used in women. Use of finasteride in pregnant women can affect the normal development of a male baby.

Women who are pregnant or may become pregnant should not handle broken or crushed Finasteride tablets. If finasteride is absorbed through the skin or taken by mouth by a woman pregnant with a male foetus, the child may be born with malformed genital organs.

If a pregnant woman is exposed to Finasteride 5 mg, immediately consult a doctor.

The tablets are film coated, which prevents contact with finasteride provided the tablets are not broken or crushed.

Always consult a doctor or pharmacist before taking this medicine.
