Dutahair is the brand name for Dutasteride in 0.5mg dosage. The medicine inhibits DHT and therefore allows hair growth. The main active ingredient in the gel caps inhibits the enzyme 5AR that converts testosterone to DHT. However, it inhibits both types of enzymes that makes the medicine more potent but also with heightened potential side effects.
At the dosage of 0.5mg per day, the medicine decreases serum DHT by 91% and scalp DHT by 54%. On the other hand, the type of 5AR that Dutahair medicine blocks is not present in significant quantity in the hair follicle.
The medicine is associated with greater incidences of sexual side effects, another side effect revealed in several cases, is that the sperm count drops significantly. Dutahair also stays in the blood stream for longer than 5 weeks. Hence, patience on this medication should not donate blood for at least 6 months after stopping the consumption of this drug.
Inability to have or maintain an erection, decrease in sex drive and issues with ejaculation are some common side effects observed while being treated with this medicine.
