Why is this medication prescribed?

Finasteride is a medication primarily prescribed for the treatment of benign prostatic hyperplasia (BPH), also known as an enlarged prostate, and male pattern baldness (androgenetic alopecia). Here’s a breakdown of its uses and how it’s typically used:

• Benign Prostatic Hyperplasia (BPH):
  • Finasteride helps in reducing the size of the prostate gland in men with BPH, which can alleviate symptoms such as difficulty urinating, weak urine flow, frequent urination (especially at night), and the feeling of not completely emptying the bladder.
  • It works by inhibiting the enzyme 5-alpha reductase, which converts testosterone to dihydrotestosterone (DHT), a hormone that contributes to prostate growth.
• Male Pattern Baldness (Androgenetic Alopecia):
  • Finasteride is also prescribed for the treatment of male pattern baldness, which is characterized by a receding hairline and thinning of hair on the scalp.
  • In this case, finasteride works by blocking the conversion of testosterone to DHT in the scalp, thereby slowing down hair loss and potentially promoting hair regrowth in some individuals.

How should this medicine be used?

Finasteride is typically taken orally, either with or without food, as prescribed by your healthcare provider. Here are some general guidelines on how to use finasteride:

• Dosage: Follow your healthcare provider’s instructions regarding the dosage of finasteride. The typical dosage for benign prostatic hyperplasia (BPH) is 5 milligrams (mg) once a day, while for male pattern baldness (androgenetic alopecia), it’s usually 1 milligram (mg) once a day. Do not exceed the prescribed dosage without consulting your healthcare provider.
• Consistency: Take finasteride regularly at the same time each day to maintain a consistent level of the medication in your body. This helps maximize its effectiveness.
• Swallow Whole: Swallow the tablet whole with a glass of water. Do not crush, chew, or break the tablet, as it may affect the release of the medication.
• Follow-up: Attend follow-up appointments with your healthcare provider as scheduled. They may monitor your progress and adjust your dosage if necessary.
• Duration of Treatment: The duration of treatment with finasteride may vary depending on the condition being treated and individual response to the medication. It’s important to continue taking finasteride as prescribed, even if you do not notice immediate improvement in symptoms. Discontinuing the medication without consulting your healthcare provider may lead to a recurrence of symptoms.
• Side Effects: Be aware of potential side effects of finasteride, such as decreased libido, erectile dysfunction, and decreased ejaculatory volume. If you experience any concerning side effects, inform your healthcare provider promptly.
• Storage: Store finasteride tablets at room temperature away from moisture, heat, and light. Keep the medication out of reach of children and pets.
• Precautions: Inform your healthcare provider about any other medications, supplements, or herbal remedies you are taking, as they may interact with finasteride. Additionally, inform them about any medical conditions you have, especially concerning liver function, as finasteride is metabolized by the liver.
• Pregnancy and Breastfeeding: Finasteride should not be handled by pregnant women, as it can be absorbed through the skin and may harm a developing male fetus. If you are pregnant, planning to become pregnant, or breastfeeding, discuss the risks and benefits of finasteride with your healthcare provider.

Always follow your healthcare provider’s instructions and guidance regarding the use of finasteride. If you have any questions or concerns about the medication, do not hesitate to discuss them with your healthcare provider.
