Finasteride is an anti-androgen drug that inhibits the conversion of peripheral testosterone to dihydrotestosterone and reduces dihydrotestosterone levels in the blood, prostate, skin and other tissues. The use of finasteride tablets is usually not associated with a wild off phase.
Finasteride is used to treat benign prostatic hyperplasia and hair loss. Studies have shown that finasteride tablets can also treat hair loss by inhibiting the enzyme 5 alpha reductase, which stops the scalp follicles around the hair loss from shrinking so that hair can grow back. The use of finasteride tablets does not usually result in a period of wild hair loss.
The use of Finasteride in some patients can cause allergic reactions such as itching, rashes, skin rashes and swelling of the mouth and lips. Decreased libido, impotence, ejaculatory disorders, and decreased ejaculate volume can occur, and testicular pain has been reported. It can also cause abdominal pain, back pain, dizziness and headache.
Finasteride needs to be used under the guidance of a doctor, and if symptoms such as hair loss are found, it is recommended to go to the hospital to find out the cause and then treat the symptoms, do not use the drug without authorization.
