Overview

Finastir 5mg Tablet is a prescription oral medicine containing finasteride 5mg, a 5-alpha reductase inhibitor. At this strength, it is used to treat benign prostatic hyperplasia (BPH) – a non-cancerous enlargement of the prostate gland – in men, helping to improve urinary flow and reduce the risk of acute urinary retention and the need for prostate-related surgery over time.

It is important to distinguish Finastir 5mg from finasteride 1mg products, which are used for a different purpose – male pattern hair loss. The two strengths are not interchangeable, and this 5mg strength should not be split or used off-label for hair loss without specific medical advice, as doing so does not reflect its approved use or established dosing for that purpose. Improvement in BPH symptoms with finasteride typically takes several months of continuous treatment to become noticeable.

How it Works

Finasteride inhibits the enzyme 5-alpha reductase, which normally converts testosterone into dihydrotestosterone (DHT), a hormone that contributes to prostate enlargement. By reducing DHT levels, finasteride helps shrink the enlarged prostate gland over time, easing pressure on the urethra and improving urinary flow.

Directions for Use

Swallow the tablet whole with a glass of water, with or without food, at approximately the same time each day. If a dose is missed, take it as soon as remembered unless it is almost time for the next dose, in which case the missed dose should be skipped – do not double the dose. Women who are or may become pregnant should avoid handling crushed or broken tablets, as finasteride can be absorbed through the skin and may harm a male foetus.

Dosage

The usual dose for BPH is one 5mg tablet taken once daily. It may take 3 to 6 months of continuous use before an improvement in symptoms becomes noticeable, and the doctor will assess response over this period. This 5mg strength must not be used interchangeably with finasteride 1mg (used for hair loss) – the prescribed strength and duration of treatment should always be confirmed with the treating doctor.

Drug / Food Interactions

  • Finasteride can lower prostate-specific antigen (PSA) test results – inform your doctor that you are taking this medicine before any PSA screening, as results may need to be adjusted when interpreting for prostate cancer risk
  • No clinically significant interactions with common medicines have been well established, but you should still inform your doctor of all medicines you are taking

Quick Tips

  • Take your tablet at the same time each day and continue treatment as prescribed, even if you do not notice an immediate change in symptoms
  • Allow at least 3 to 6 months of continuous use before assessing whether the medicine is working, and discuss progress with your doctor at follow-up visits
  • Tell your doctor you are taking finasteride before any PSA blood test, as it affects the result
  • Pregnant women or women who may become pregnant should avoid handling crushed or broken tablets
