Dutasteride: Uses, Dosage, and Side Effects You Should Know
Summary of Key Points
Dutasteride is a prescription medication commonly used to treat conditions such as benign prostatic hyperplasia (BPH), male pattern baldness, and certain hormonal imbalances. It works by reducing the levels of dihydrotestosterone (DHT), a hormone that can contribute to prostate enlargement and hair loss. By lowering DHT, Dutasteride helps shrink an enlarged prostate and may also encourage hair growth. Always consult your healthcare provider before starting or adjusting your dose. You can easily connect with one of our telemedicine providers for personalized advice.

Contraindications for Dutasteride
A contraindication is a specific situation or condition where a medication should not be used because it may cause harm or worsen a patient’s health. If you have any of the following conditions, you should avoid taking Dutasteride:
Pregnancy: Dutasteride is contraindicated in women who are pregnant or may become pregnant. This is because Dutasteride can cause birth defects, particularly in the development of male fetuses. Even handling the medication can be harmful if the capsule is broken or leaking.
Severe liver disease: If you have significant liver impairment, your body may not be able to process Dutasteride properly, leading to a buildup of the drug in your system. This can increase the risk of side effects.
Allergic reactions: If you have had an allergic reaction to Dutasteride or similar medications (such as finasteride), you should not take this medication. Symptoms of an allergic reaction may include rash, itching, swelling, or difficulty breathing.
Drug-to-Drug Interactions with Dutasteride
Some medications can interact with Dutasteride, potentially increasing the risk of side effects or reducing the effectiveness of either drug. If you are taking any of the following medications, be sure to inform your healthcare provider:
- Ketoconazole (Nizoral): This antifungal medication can increase the levels of Dutasteride in your bloodstream, potentially leading to more side effects.
- Verapamil (Calan, Verelan): A medication used to treat high blood pressure and heart conditions, it may affect how your body processes Dutasteride.
- Diltiazem (Cardizem): Another heart medication that can interfere with the metabolism of Dutasteride, leading to increased drug levels.
- Ritonavir (Norvir): Used to treat HIV, this drug can increase the concentration of Dutasteride in the body.
- Cimetidine (Tagamet): A medication used to treat heartburn and ulcers, it may affect how Dutasteride is metabolized.
Dutasteride in Pregnancy
Is it safe to take Dutasteride when pregnant?
No, Dutasteride is not safe during pregnancy. It is strictly contraindicated due to its potential to cause serious birth defects, particularly in male fetuses, as it can interfere with the development of male genitalia. Pregnant women should avoid handling the medication, especially if the capsules are broken or leaking, as the drug can be absorbed through the skin. If you are pregnant or planning to become pregnant, consult your healthcare provider immediately to discuss safer alternatives.
Dutasteride while Breastfeeding
Is it safe to take Dutasteride while breastfeeding?
No, Dutasteride is not recommended during breastfeeding. Although there is limited data on whether Dutasteride passes into breast milk, the potential risks to a nursing infant are unknown. Since Dutasteride is not typically prescribed for women, especially those who are breastfeeding, it is essential to consult your healthcare provider about alternative treatments.

Always consult your healthcare provider before making any changes to your treatment plan. You can also schedule a telemedicine appointment with one of our providers to discuss these alternatives in more detail.
Benign Prostatic Hyperplasia (BPH)
Alternatives include medications such as tamsulosin (Flomax) or finasteride (Proscar). Lifestyle changes, like reducing caffeine and alcohol intake and practicing bladder training exercises, may also provide relief.
Prostate Cancer
Treatment options may include surgery, radiation therapy, or hormone therapy. Medications like abiraterone (Zytiga) or enzalutamide (Xtandi) may also be considered, depending on the stage and progression of the disease.

Androgenetic Alopecia
Minoxidil (Rogaine) and finasteride (Propecia) are frequently used to treat androgenetic alopecia. Platelet-rich plasma (PRP) therapy and lifestyle changes, such as maintaining a nutrient-rich diet, may also support hair health.
Hormonal Imbalance
Hormone replacement therapy (HRT) or medications that help regulate hormone levels may be prescribed. Additionally, lifestyle modifications, such as stress management and a balanced diet, can play a key role in supporting hormonal balance.
Urinary Retention
Medications like tamsulosin (Flomax) or surgical procedures to remove blockages may be considered. Pelvic floor exercises and bladder training can also help improve symptoms.
Urinary Tract Symptoms
Alpha-blockers like tamsulosin (Flomax) or anticholinergics such as oxybutynin (Ditropan) may be prescribed to alleviate symptoms. Staying hydrated and avoiding irritants like caffeine can also be beneficial.
Enlarged Prostate
In addition to Dutasteride, medications like finasteride (Proscar) or alpha-blockers such as tamsulosin (Flomax) are common alternatives. In more severe cases, surgical options may be necessary.
Hair Loss
Minoxidil (Rogaine) and finasteride (Propecia) are the most widely used treatments for hair loss. Hair transplants or laser therapy may also be considered, depending on the severity of the condition.
Scalp Hair Thinning

Recent Updates on Dutasteride Research
Recent research on Dutasteride has explored its potential role in prostate cancer prevention. Some studies suggest that Dutasteride may reduce the risk of developing prostate cancer in men at higher risk, although it is not currently approved for this purpose. Ongoing research is also investigating the long-term effects of Dutasteride on hair regrowth and its potential benefits in treating male pattern baldness. However, more studies are needed to confirm these findings and to better understand the risks and benefits of long-term use.
As always, it is important to discuss any new research or treatment options with your healthcare provider. If you have questions about Dutasteride or want to explore whether it is right for you, schedule a telemedicine appointment with one of our providers today.
