Overview- Propecia and male baldness
Male pattern baldness (or androgenetic alopecia) is the most well-known cause of hair loss among men. It involves the thinning of hair, mostly starting the scalp. The result is a receding hairline, which may or may not be accompanied by balding at the top of the manâs head. Some men may be distressed by this condition especially if it happens early in life. Nearly one in every four men with this condition starts losing their hair before attaining 21 years of age.
To combat this problem, the drug manufacturing company Merck & Co, in 1997, developed and secured FDA (Food and Drug Administration) approval to market Propecia to treat hair loss in men. After the drug underwent rigorous FDA trials, it has since become the most popular prescription treatment for hair loss in men. Its active ingredient is finasteride, which is sold in 1 milligram tablets. A different formulation of 5 milligrams per tablet is also used to treat prostate enlargement (also called benign prostrate hyperplasia)
How it works
Hair comes from the hair follicles under the skin. A single strand of hair lasts for nearly three years before being shed and replaced by a new one. The balding process makes the hair follicles and the hair strands to become progressively thinner. Eventually they stop breaking out above the skinâs surface- hence baldness. This occurs because the hair follicles start to convert the testosterone male hormone to another type of hormone called dihydrotestosterone (DHT).The result is shrinkage of the hair follicles. The finasteride in Propecia interferes with this process by blocking the enzyme called 5-alpha reductase, which is responsible for this conversion. It causes the levels of DHT in the scalp and blood to drop significantly.
A single tablet of 1 milligram of the medication should be taken once every day, with or without meals. It is advisable for the patient to take the dose at the same hour so they do not forget. The tablet should be taken with water without being broken or crushed. Users are also advised not to make up for missed doses.
The medication may take up to one year or more before its effects of hair loss prevention and hair regrowth are felt. During the first six months, the user may still experience some thinning in their hair. This may be because Propecia has not had the chance to work properly or due to the old hair that is yet to be shed before the new healthy hair takes root.
Side effects and contraindications
One should urgently get medical help if they get allergic reactions such as swollen lips, face, throat or tongue. Other allergic reactions include difficulties while breathing or hives. It is also advisable to call a doctor when one notices nipple discharge, breast lumps or breast pains or any other unusual changes in the breasts. This is because such changes may indicate breast cancer.
Propecia usage may also cause less severe effects such as impotence, low libido, unusual ejaculation, breast tenderness, swollen feet or hands, faintness, skin rashes, running nose or headaches.The sexual effects such as low libido may persist even after one stops taking the medication. It is therefore recommended that a user talks to their doctor regarding such concerns.
Before using Propecia, a person should talk to their doctor if they are suffering from certain medical conditions like liver complications, prostate cancer, urethra and bladder muscle problems or if they have experienced allergic reactions after taking dutasteride(a similar medicine that is used in the treatment of enlarged prostrate conditions).
Propecia may increase the probability of a person getting cancer of the prostate. A qualified physician should conduct tests to ensure one does not suffer from other conditions which may prevent them from using finasteride safely.
Women and children should not use Propecia and they should also not handle it since it can be absorbed through the skin .The tablets are coated to prevent coming into contact with the skin. If a woman or child handles a crushed or broken tablet, any area of contact must be immediately cleaned thoroughly using soap and water.
Propecia and body hair
Using finasteride to rejuvenate the growth of scalp hair may hinder the growth of a personâs body hair. This is because DHT, which is blocked by finasteride, encourages growth of body hair in men. But because of the generic variations that exist among individuals, it is difficult to determine how a person responds to it. Nevertheless, finasteride does not enhance the growth of body hair.
The medication should be stored in a cool dry place away from children.
