1. What is Nezyr and what is it used for
This medicine contains the active substance finasteride.
Nezyr is intended for use by men only.
Nezyr is used to treat male pattern hair loss (also known as androgenetic alopecia) in men aged 18 to 41 years. If, after reading this leaflet, you have any questions about male pattern hair loss, you should consult your doctor.
Male pattern hair loss is a common condition that is caused by a combination of genetic factors and a specific hormone - DHT (dihydrotestosterone).
DHT causes the hair growth phase to shorten and the hair to become thinner.
Finasteride lowers the level of DHT in the scalp by blocking the enzyme (5-alpha-reductase type II) that converts testosterone to DHT. Only men with mild to moderate, but not complete, hair loss can expect to benefit from Nezyr. In most men treated with Nezyr for 5 years, the progression of hair loss has slowed down, and in at least half of these men, there has also been an improvement in hair growth.

When not to take Nezyr
Warnings and precautions
Before taking Nezyr, discuss it with your doctor or pharmacist.
Effect on Prostate-Specific Antigen (PSA)
Finasteride may affect a blood test called PSA (Prostate-Specific Antigen) for prostate cancer. If you are going to have a PSA test, tell your doctor or pharmacist that you are taking Nezyr, as finasteride may affect the PSA levels.
Breast Cancer
See section 4 "Possible side effects".
Mood Changes and Depression
Patients taking finasteride have reported depressed mood, depression, and less frequently, suicidal thoughts. If you experience any of these symptoms, stop taking Nezyr and consult your doctor immediately.
Children and Adolescents
Nezyr should not be taken by children or adolescents. There is no data on the efficacy or safety of finasteride in children or adolescents under 18 years of age.
Nezyr and other medicines
Tell your doctor or pharmacist about all the medicines you are taking, or have recently taken, and about any medicines you plan to take.
Pregnancy, Breast-feeding, and Fertility
Nezyr, 1 mg is used to treat male pattern hair loss, in men only.
- Nezyr must not be taken by women, due to the possible risk of pregnancy.
- Women who are pregnant or think they may be pregnant should not handle crushed or broken Nezyr tablets.
- If the active substance of Nezyr is absorbed through the skin or taken orally by a woman carrying a male fetus, the child may be born with genital malformations.
- If a pregnant woman has come into contact with the active substance of Nezyr, she should consult her doctor.
- The tablets of Nezyr are film-coated to prevent contact with the active substance during normal use.
Effects on Fertility
There have been reports of infertility in men taking finasteride for a long time, who had other risk factors for fertility. Normalization or improvement of semen quality has been observed after discontinuation of finasteride treatment. However, no long-term studies have been conducted on the effects of finasteride on fertility in men.
In case of doubt, consult your doctor.
