I believe that friends of patients with benign prostatic hyperplasia or androgenetic alopecia have all known about a drug called " finasteride ", or they have been taking it for a long time.
Finasteride is an inhibitor of intracellular enzyme type II 5α-reductase. In short, its main principle is " anti-androgen ".
For patients with benign prostatic hyperplasia, finasteride can effectively reduce the dihydrotestosterone in the blood and the prostate, thereby improving the hypertrophy of the prostate, relieving symptoms such as frequent urination and urgency, and controlling the progression of the disease.
For patients with androgenetic alopecia, finasteride can reduce the concentration of dihydrotestosterone in the scalp and blood, thereby avoiding further shrinkage of hair follicles, reversing the process of hair loss, and promoting hair regeneration.
So how long does finasteride take for these patients? What problems should I pay attention to when taking the medicine for a long time? Let's talk about it in this article.
How should Finasteride be taken? How long will it take?
Here, we would like to emphasize that in order to ensure the efficacy and safety, finasteride needs to be taken in strict accordance with the doctor's order.
" If you belong to the "adult symptomatic benign prostatic hyperplasia patient": generally takes 5mg Xianlixiao tablets and Baolizhi tablets. The dosage is once a day, one tablet each time. After 12 weeks to 6 months, evaluate the effect of the medication or as directed by your doctor.
"If you are a male androgenetic alopecia patient: generally takes Xianju tablets of 1mg specification, the dosage is once a day, one tablet each time. The effective rate of Xianju Tablets for patients with androgenetic alopecia can reach about 70%-90%, and the safety is good, but the premise is that the patient needs to take it as required for three consecutive months or more.(It may take 1-2 years for non-mild patients to achieve the best curative effect) Nasteride has a low risk of side effects, and most side effects are reversible. As long as the patient tolerates the drug and has clear treatment needs, it can be taken for a long time or even for life under the guidance of a doctor.
What should I pay attention to when eating for a long time?
First of all, finasteride is only for adult males. Finasteride is suitable for "male patients" with benign prostatic hyperplasia or hair loss. It should be avoided for special groups such as children and women, especially pregnant women, try to avoid exposure to finasteride as it may affect the fetus.
Second, finasteride does not cause prostate cancer, but it may mask prostate cancer signals. Therefore, it is recommended that patients with benign prostatic hyperplasia who take finasteride for a long time should pay attention to communicate with the doctor before taking the drug, and do relevant inspections.
In addition, finasteride needs to be metabolized by the liver, resulting in an increase in indicators such as liver transaminase. If you take finasteride for a long time, especially friends who have liver disease , be sure to check your liver function regularly.
Last but not least, no matter if you are taking 5mg or 1mg, please take the medicine strictly according to the doctor's order. Do not increase the dose of the drug arbitrarily for the sake of the effect, or take the drug apart and eat it. Go to hospital for treatment and inform the doctor about the situation.
If you forget to take your medicine that day, take the same day's dose as soon as possible, never take twice the dose at one time.
There are domestic and imported finasteride, what is the difference?
domestic ≠ poor effect.
At present, the drug R&D and production capacity of major domestic pharmaceutical companies are not bad. There is a drug consistency evaluation standard in China. They can be substituted for each other clinically.
In the vernacular, the safety and efficacy of regular domestic drugs can almost reach the level of imported drugs. More importantly, from the indications of finasteride, patients basically need long-term medication. For some patients and friends, choosing domestic drugs whose price is less than one-third of imported drugs can significantly reduce the economic burden of drug use.
