DUTAAS-0.5

# Dutasteride 0.5 mg ## SHORT DESCRIPTION **Dutasteride 0.5 mg** is a prescription medicine belonging to a group of medicines called **5-alpha-reductase inhibitors**. It is primarily used to treat **benign prostatic hyperplasia (BPH)**, a non-cancerous enlargement of the prostate gland. Dutasteride reduces the production of **dihydrotestosterone (DHT)**, a hormone that contributes to prostate enlargement. It may improve urinary symptoms and reduce the risk of acute urinary retention and BPH-related surgery. Dutasteride is also sometimes used off-label for **male pattern hair loss**, but this use should be supervised by a qualified healthcare professional. ## KEY BENEFITS * Helps reduce an enlarged prostate * Can improve urinary flow and BPH-related urinary symptoms * Helps reduce the risk of acute urinary retention * May reduce the likelihood of BPH-related prostate surgery * Lowers DHT levels by inhibiting 5-alpha-reductase * May help slow prostate enlargement over time * May promote hair growth in some men when used off-label for male pattern hair loss ## USES / INDICATIONS Dutasteride 0.5 mg is primarily indicated for: * **Benign prostatic hyperplasia (BPH)** * Improvement of urinary symptoms associated with an enlarged prostate * Reduction of the risk of acute urinary retention * Reduction of the need for BPH-related surgery ### Off-label use Dutasteride may sometimes be prescribed off-label for **androgenetic alopecia (male pattern hair loss)** because DHT contributes to hair follicle miniaturization. **Dutasteride is not approved for treating prostate cancer.** ## HOW IT WORKS Dutasteride inhibits both **type 1 and type 2 5-alpha-reductase enzymes**. These enzymes convert testosterone into **dihydrotestosterone (DHT)**. DHT contributes to prostate growth and plays an important role in androgen-dependent hair loss. By substantially reducing DHT levels, dutasteride: * Helps shrink an enlarged prostate * Improves urinary symptoms associated with BPH * Reduces the risk of urinary retention and BPH-related surgery * May reduce hair follicle miniaturization in men with androgenetic alopecia Dutasteride has a **long half-life**, so it can remain in the body for an extended period after stopping treatment. ## DOSAGE & ADMINISTRATION ### For BPH * The usual adult dose is **0.5 mg once daily**. * Take the medicine exactly as prescribed. * Swallow the capsule whole with water. * It may generally be taken with or without food. * Do not crush, chew, or open the capsule. * Take it at approximately the same time each day. * Dutasteride may take several weeks to months to provide its full therapeutic benefit. ### Missed dose If you miss a dose, take it when remembered unless it is close to the next scheduled dose. Do not take two doses together. ### Important handling information **Women who are pregnant or may become pregnant should not handle leaking dutasteride capsules.** Dutasteride can be absorbed through the skin and may potentially harm a male fetus. ## SIDE EFFECTS Common side effects may include: * Reduced libido * Difficulty achieving or maintaining an erection * Decreased amount of semen released during ejaculation * Ejaculation problems * Breast tenderness or enlargement * Dizziness in some patients Sexual adverse effects may occur during treatment and, in some cases, may persist after discontinuation. ### Serious side effects Seek medical attention if you experience: * Breast lumps, breast pain, or nipple discharge * Severe allergic reaction * Facial or throat swelling * Difficulty breathing * Severe skin reactions ## PRECAUTIONS & WARNINGS ### Pregnancy Dutasteride is **contraindicated in women who are pregnant or may become pregnant** because inhibition of DHT can interfere with development of male external genitalia. Pregnant women should not handle leaking capsules. ### Blood donation Men taking dutasteride should **not donate blood during treatment and for at least 6 months after the final dose**, because dutasteride can remain in the bloodstream for a prolonged period and could potentially expose a pregnant recipient. ### PSA testing Dutasteride lowers **prostate-specific antigen (PSA)** levels. This can affect the interpretation of PSA tests used in prostate evaluation. Tell your doctor that you are taking dutasteride before having a PSA test. ### Liver disease Dutasteride is extensively metabolized by the liver. Tell your doctor if you have liver disease or abnormal liver function. ### Prostate cancer Dutasteride is not a treatment for prostate cancer. Men taking dutasteride should continue appropriate prostate evaluation as recommended by their doctor. ### Sexual function Dutasteride can affect libido, erections, ejaculation, and semen volume. Discuss persistent or troublesome sexual side effects with your healthcare professional. ## DRUG INTERACTIONS Dutasteride has fewer clinically important interactions than some other medicines, but interactions can occur. Tell your doctor or pharmacist if you take: * **Ketoconazole** * **Ritonavir** * **Indinavir** * **Verapamil** * **Diltiazem** * Other medicines that strongly inhibit CYP3A4 or CYP3A5 These medicines may increase dutasteride exposure.
