We also anticipate being able to handle more complex scenarios such as using primary insurance combined with a manufacturer copay assistance program.

What should you do if you use too much finasteride?


Call your doctor right away or seek immediate medical attention if your symptoms do not improve or they become worse after using finasteride. You can also call 800-222-1222 to reach the American Association of Poison Control Centers or use its online resource if you think you’ve used too much finasteride. But if you have severe symptoms, call 911 (or your local emergency number) immediately or go to the nearest emergency room.


If you think it is an emergency, call 999 or find your nearest A&E
If you need help now, but it’s not an emergency go to 111.nhs.uk or call 111. Alternatively you can speak to one of our pharmacists or use the Now Patient app to make an appointment with your GP.

What should I do if I miss my dose?

There are occasions when people forget to take their medication at correct prescribed times. This may not only have an effect on potentially making the medication less effective but it may also inadvertently lead to taking doses too close together, thereby increasing the risks of side effects.

FDA approval of finasteride

Finasteride has received FDA approval for the treatment of male pattern hair loss (Propecia) and benign prostatic hyperplasia (Proscar).

Active ingredient of finasteride and mechanism of action

The active ingredient in finasteride is finasteride. It belongs to a class of medications called 5-alpha-reductase inhibitors. Finasteride works by inhibiting the enzyme 5-alpha-reductase, which converts testosterone to dihydrotestosterone (DHT). By reducing DHT levels, finasteride helps to slow down hair loss and shrink the enlarged prostate in benign prostatic hyperplasia.

Uses of finasteride

Finasteride is used for the following conditions:

  • Male pattern hair loss (androgenetic alopecia): Finasteride (Propecia) is used to help hair growth in male pattern baldness in men
  • Benign prostatic hyperplasia (BPH): Finasteride (Proscar) is used to treat symptoms of BPH, such as urinary frequency, urgency, and incomplete bladder emptying

Forms of finasteride

Finasteride is available in the form of oral tablets. The specific strength and formulation will depend on the prescribed dosage and the brand.

Dosage of finasteride

The dosage of finasteride will vary depending on the specific indication and individual patient factors. It is important to follow the patient information and medical advice provided by your healthcare provider.
If you miss a dose of this medicine, skip the missed dose and go back to your regular dosing schedule. Do not double doses.


Store at room temperature away from light and moisture. Do not store in the bathroom. Keep all medications away from children and pets.

Precautions and warnings for finasteride

  • Finasteride tablets are contraindicated in women and children. It should only be used by adult men with male pattern hair loss or benign prostatic hyperplasia (BPH)
  • Use of finasteride in women, especially pregnant women is contraindicated. Finasteride can be absorbed through the skin and may cause harm to a developing fetus. Pregnant women or those who are planning to become pregnant should avoid handling crushed or broken tablets of finasteride
  • Men with liver disease may need a lower dose of finasteride due to the decreased ability to metabolize the medication. Additionally, men with prostate cancer should not use finasteride as it may shrink the prostate and interfere with diagnostic tests for this condition
  • It is important to inform your healthcare provider about any medical conditions, including liver disease, prostate cancer, or urinary problems, before starting finasteride
  • Finasteride may cause sexual side effects, such as decreased libido, sexual dysfunction, erectile dysfunction, and ejaculation disorders. These side effects may persist even after discontinuation of the medication
  • Inform your healthcare provider about all the medications you are taking, including prescription drugs, over-the-counter medications and supplements to avoid adverse effects
  • Regular follow-up visits and monitoring of prostate-specific antigen (PSA) levels may be necessary for men taking finasteride for BPH
