Finasteride
About Finasteride
Finasteride is a prescription medicine primarily used to treat male pattern hair loss (androgenetic alopecia) and benign prostatic hyperplasia (an enlarged prostate). It helps manage these conditions in men by targeting specific hormonal pathways in the body. By addressing these concerns, it helps restore hair coverage on the scalp and improves uncomfortable urinary symptoms.
For the best results, you must take Finasteride consistently every day, as directed by your healthcare provider. You can take this medicine with or without food, making it easy to fit into your daily routine. Combining this treatment with a balanced diet, proper scalp care, and regular prostate health check-ups can help optimise your long-term results.
While taking Finasteride, you may experience mild side effects, such as a temporary decrease in sexual desire or mild difficulties with erections. However, you must consult your doctor immediately if you experience serious side effects, including unusual breast changes like lumps, pain, or nipple discharge, or severe mood shifts like depression.
Do not take this if you have a history of severe allergic reactions to similar medications. Talk to your doctor before starting this medicine if you have a history of liver damage, bladder conditions, or difficulty urinating. This medicine is not intended for use by women or children; pregnant women, in particular, should not take this medicine or handle crushed tablets.
Finasteride can interact with certain other medications, so it is important to share your full medical history with your pharmacist. While moderate alcohol use is not strictly forbidden, limiting alcohol and smoking can support overall prostate and circulatory health. Elderly individuals and those with existing liver conditions should consult their doctor for personalised guidance before starting treatment.

Patients Concern
Disease/Condition Glossary
Benign prostatic hyperplasia (BPH): Benign prostatic hyperplasia, also called prostate enlargement, is the non-cancerous growth of the prostate gland due to the multiplication of cells. This leads to swelling and squeezing of the urethra and limits the urine flow. It is an age-associated prostate gland enlargement which can cause problems with urination. BPH symptoms include loss of bladder control, frequent urination, inability to urinate, incomplete bladder emptying, weak urinary stream, dribbling at the end of the urinary stream, sudden urge to urinate, and painful urination.
Male pattern hair loss: In male pattern hair loss, gradual thinning of the hair on the scalp occurs, which leads to a receding hairline or balding on the top of the head in men. It is usually genetic in nature or associated with androgens (male sex hormones).
