Dutasteride is a prescription medication specifically formulated to manage and treat benign prostatic hyperplasia (BPH), commonly known as an enlarged prostate. As a 5-alpha-reductase inhibitor, it works by reducing the production of dihydrotestosterone (DHT), a hormone that contributes to prostate growth. This leads to a decrease in prostate size, alleviating urinary symptoms and improving overall quality of life. Clinically proven and widely prescribed, dutasteride offers a reliable solution for men seeking long-term control of BPH symptoms.
Features
- Active ingredient: Dutasteride 0.5 mg
- Mechanism: Dual inhibitor of Type I and Type II 5-alpha-reductase enzymes
- Form: Oral soft gelatin capsules
- Bioavailability: Approximately 60% when taken with food
- Half-life: ~5 weeks at steady state
- Excretion: Primarily via feces
Benefits
- Reduces prostate size, alleviating pressure on the urethra
- Improves urinary flow and reduces frequency of urination
- Decreases the risk of acute urinary retention and need for surgery
- Provides long-term management of BPH symptoms with once-daily dosing
- Enhances overall quality of life by restoring normal urinary function
- Clinically proven to be effective in numerous large-scale studies
Common use
Dutasteride is primarily indicated for the treatment of symptomatic benign prostatic hyperplasia in men with an enlarged prostate. It is used to improve urinary symptoms such as weak stream, hesitancy, dribbling, and nocturia. It may also be used in combination with alpha-blockers like tamsulosin for enhanced therapeutic effect. In some cases, it is prescribed off-label for androgenetic alopecia (male pattern hair loss), though this is not its primary approved indication.
Dosage and direction
The recommended dosage is one 0.5 mg capsule taken orally once daily, with or without food. It should be swallowed whole; the capsule must not be crushed, chewed, or opened. Consistency in daily administration is important to maintain stable drug levels. It may take up to 6 months of continuous use to observe maximum symptomatic improvement. Dosage adjustments are not typically required for elderly patients or those with renal impairment, but caution is advised in hepatic impairment.
Precautions
- Not for use in women or children
- May cause fetal harm if handled by pregnant women; avoid contact with crushed or broken capsules
- Regular monitoring of prostate-specific antigen (PSA) levels is required, as dutasteride reduces PSA concentrations
- Patients should be informed about the potential for sexual side effects
- Caution advised in patients with liver disease
- Periodic digital rectal examinations recommended to monitor prostate changes
Contraindications
- Hypersensitivity to dutasteride, other 5-alpha-reductase inhibitors, or any component of the formulation
- Pregnancy (Category X) - women who are or may become pregnant must not use or handle crushed capsules
- Pediatric use
Possible side effects
Common side effects may include:
- Decreased libido (3-4%)
- Erectile dysfunction (5-7%)
- Ejaculation disorders (1-4%)
- Gynecomastia (breast enlargement and tenderness) (1-2%)
Less common side effects:
- Testicular pain
- Depression
- Allergic reactions including rash, pruritus, and urticaria
- Hair loss (non-scalp) or body hair changes
Drug interaction
- Potent CYP3A4 inhibitors (e.g., ritonavir, ketoconazole) may increase dutasteride concentrations
- Alpha-adrenergic blockers (e.g., tamsulosin) are often co-administered without significant interaction
- No clinically significant interactions with warfarin, digoxin, or cholestyramine
- Caution with other medications that affect hormonal balance
Missed dose
If a dose is missed, it should be taken as soon as remembered unless it is almost time for the next dose. Do not double the dose to make up for a missed one. Maintain regular dosing schedule; consistency is more important than exact timing.
Overdose
No specific antidote exists for dutasteride overdose. Single doses up to 40 mg have been administered without adverse effects. In case of suspected overdose, symptomatic and supportive treatment is recommended. Dialysis is unlikely to be beneficial due to high protein binding.
Storage
Store at room temperature (20-25°C or 68-77°F); excursions permitted between 15-30°C (59-86°F). Keep in original container, tightly closed, and protect from light and moisture. Keep out of reach of children and pets. Do not use after expiration date.
