Dutasteride for hair loss has become one of the most searched topics among men who have tried finasteride and want to know what comes next. Dutasteride is the active ingredient in Avodart, a 0.5 mg capsule first made for an enlarged prostate. Because it lowers the hormone behind male pattern hair loss even more than finasteride does, many doctors now prescribe it for thinning hair as well.
This guide explains how dutasteride works, how it compares with finasteride, what results are realistic, the side effects to know about and how to order generic dutasteride 0.5 mg with your prescription. It is written for readers in the US, UK, Canada, Europe and elsewhere. Always talk to your doctor before starting or changing a hair loss treatment.
Key takeaways
- Dutasteride blocks both forms of the enzyme that turns testosterone into DHT, the hormone that shrinks hair follicles.
- It lowers DHT more than finasteride, which is why some doctors use it when finasteride has not been enough.
- The usual dose for hair loss is one 0.5 mg capsule a day. Results take 6 to 12 months to judge.
- Women who are or may become pregnant must not handle broken or leaking capsules.
- Dutasteride stays in the body for weeks, so tell your doctor before blood tests and do not donate blood during treatment.
- A valid prescription is required for every order of a prescription medicine.
How dutasteride works on hair loss
Male pattern hair loss happens when hair follicles on the top and front of the scalp react to dihydrotestosterone, or DHT. Over time, DHT makes these follicles smaller, so the hairs they grow become thinner and shorter until some stop growing at all.
DHT is made from testosterone by an enzyme called 5-alpha reductase. This enzyme comes in two main forms, type 1 and type 2. Finasteride blocks only type 2. Dutasteride blocks both, so it lowers DHT in the blood by more than 90 percent, compared with around 70 percent for finasteride. Less DHT means less pressure on the follicles, which can slow hair loss and, for many men, thicken existing hair.
Dutasteride vs finasteride
| Point | Dutasteride 0.5 mg | Finasteride 1 mg |
|---|---|---|
| Enzymes blocked | Type 1 and type 2 | Type 2 only |
| Fall in blood DHT | Over 90 percent | Around 70 percent |
| Time in the body after stopping | Several weeks to months | A few days |
| Form | Soft capsule | Tablet |
| Typical use for hair loss | Often when finasteride has not worked well enough | Usually the first tablet tried |
Studies comparing the two have found dutasteride 0.5 mg produced more hair growth than finasteride 1 mg on average. The trade-off is that dutasteride lasts much longer in the body, so if side effects happen they take longer to fade after stopping. Your doctor will weigh this with you. If you are still deciding, our guide to finasteride for hair loss covers the more common first option. Do not take dutasteride and finasteride together.
How to take generic dutasteride 0.5 mg
- Take one 0.5 mg capsule once a day, with or without food, at about the same time each day.
- Swallow the capsule whole with water. Do not chew or open it, as the contents can irritate the mouth and throat.
- If you miss a dose, skip it and take the next one at the usual time. Do not take two capsules together.
- Keep going for at least 6 to 12 months before judging the result. Hair grows slowly and some extra shedding in the first months can happen as old hairs make way for new ones.
- Taking photos of your scalp in the same light every three months makes progress easier to see.
Safety: who should not take dutasteride
- Women and children. Dutasteride is a treatment for men. It can harm a developing male baby, so women who are or may become pregnant must not handle broken or leaking capsules. If contact happens, wash the skin straight away with soap and water.
- Anyone allergic to dutasteride, to similar medicines or to any capsule ingredient.
- Men with serious liver problems, unless their doctor advises it.
Blood tests and blood donation
Dutasteride roughly halves the level of PSA, a blood marker used to check the prostate. Tell any doctor who orders a PSA test that you take it, so the result can be read correctly. Because dutasteride stays in the blood for a long time, do not donate blood while taking it and for at least six months after your last dose.
Side effects
Most men have no side effects. The ones reported most often are lower sex drive, problems getting an erection, less semen and breast tenderness or enlargement. These usually ease over time or after stopping, though with dutasteride this can take longer than with finasteride. Tell your doctor about any change in mood, any breast lump or nipple discharge, or signs of an allergic reaction such as swelling of the face or a rash.
Generic Avodart: why it costs less
The first maker of a medicine prices it to recover the cost of research and trials. Once the patent ends, other makers can produce the same active ingredient without repeating that work, and competition lowers the cost. Generic dutasteride 0.5 mg contains the same active ingredient at the same strength as Avodart. The capsule may look different, but the dose is the same.
Hair loss treatment is long term, because the benefit only lasts while you keep taking it. Choosing a generic is a practical way to keep a daily treatment affordable over years.
