Propecia is a drug designed for long-term use and is used to combat male pattern baldness. It helps stimulate hair growth and reduces hair loss.
How does it work?
Propecia contains the active ingredient finasteride, which has a beneficial effect. However, the drug should be taken for at least six months to see results. In addition, it should be taken for a long time to completely stop hair loss. Thanks to these pills, you can significantly slow down hair loss or completely stop it. Hair growth can be partially restored.
Propecia is prescribed for the treatment of male pattern baldness (androgenetic alopecia) to enhance hair growth and prevent its further loss.
The drug is not intended for women or children.
The drug will not be effective in the treatment of androgenetic alopecia in women in the postmenopausal period.
Dosage and route of administration
The recommended dose is one 1 mg tablet daily, regardless of the meal.
It usually takes 3 or more months of daily use of the drug before you notice an increase in hair growth and/or a decrease in the rate of hair loss. It is recommended that treatment be continued for maximum results. Discontinuation of the drug leads to a return to the previous state within 12 months.
Propecia is contraindicated in the following cases:
- Women should avoid contact with the drug when they are pregnant or potentially pregnant;
- Hypersensitivity to any ingredients of the drug;
- The drug should not be taken by women or children.
Pregnancy and breastfeeding
Pregnant women, as well as women who may potentially be pregnant, should avoid contact with finasteride (Propecia).
Due to the ability of type II 5a-reductase inhibitors to inhibit the conversion of testosterone in some tissues, drugs that include finasteride can cause abnormalities in the external genitalia of the male fetus when taking finasteride in a pregnant woman.
This drug should not be prescribed to women. It is not known whether finasteride passes into mother’s milk.
No clinically significant drug interactions were noted. Finasteride does not seem to have a noticeable effect on the cytochrome P450 enzyme system. In studies on volunteers, no clinically significant interaction was found with antipyrine, digoxin, glyburide, propranolol, theophylline and warfarin.
Although no specific interaction studies were performed, in clinical trials finasteride at a dose of 1 mg or more was used in conjunction with ACE inhibitors, acetaminophen, alpha-blockers, benzodiazepines, beta-blockers, calcium channel blockers, nitrates, diuretics, H2 antagonists, G inhibitors CoA (HMG-CoA) reductase inhibitors, prostaglandin synthesis inhibitors (NSAIDs – non-steroidal anti-inflammatory drugs) and quinolones, with no clinically significant adverse reactions detected.
Propecia can cause side effects. Sometimes men have a decreased desire for sexual intercourse or difficulties with achieving and keeping an erection. Fewer men may notice a decrease in ejaculate volume (but this does not seem to counteract normal sexual function). These undesirable effects are reflected both in men who stop taking these pills and in many men who continue treatment.
Some men taking Propecia also reported:
- Pain and enlargement of the mammary glands;
- Decreased libido that persists after drug withdrawal;
- Allergic reactions, including rash, itching, hives, swelling of the lips, tongue, pharynx, and face;
- Problems with ejaculation that persist after drug withdrawal;
- Testicular pain;
- Erectile problems that persist after drug withdrawal;
- Male infertility and / or poor sperm quality. Sperm quality improvement has been reported after drug withdrawal.
In very rare cases, breast cancer has been reported.
Propecia does not affect hair growth in other parts of the body.
Tell your doctor or pharmacist about any unusual symptoms right away.
If you notice any side effects not listed here, you should inform your doctor or pharmacist.
In clinical studies, a single dose of finasteride up to 400 mg and multiple doses up to 80 mg/day for three months did not lead to any side effects.
There are no specific recommendations regarding the treatment of overdose of finasteride.
Tell your doctor about any health problems you have or have had, and any known allergies. The doctor will decide if you should take Propecia or not.
If you notice changes in breast tissue such as lumps, pain, breast enlargement, or discharge from the nipple, you should consult a doctor immediately. These signs may indicate a serious condition, such as breast cancer.
Propecia usually does not interact with other medicines. However, you should always tell your doctor about all the medicines you take or plan to take, including those that you have taken without a prescription.
There is no indication that this drug affects the ability to drive or use a car.
Benefits of the drug
Propecia, unlike many other anti-baldness remedies, does not adversely affect the human body. After the first course of taking the drug, the process of hair loss slows down or even stops altogether. It is worth noting that the use of this remedy is recommended only to those who have an androgenic type of baldness. This drug has repeatedly proved its high effectiveness.
One of the causes of male pattern baldness is the predominance of dihydrotestosterone in the body. Finasteride blocks its production. Thanks to the action of this drug, the death of the hair follicles stops. The drug also helps restore hairline but it may take some time. After achieving the result, it is recommended to take the pills for some time.
