How long does Finasteride stay in your system?
28th May 2019
Finasteride is a hair loss medication that is used for the treatment of an enlarged prostate or hair loss in men. Finasteride is a man-made 4-azasteroid compound that specifically inhibits steroid Type II 5a-reductase, the enzyme in the cells that allows the conversion of the androgen testosterone into 5a-dihydrotestosterone or DHT. It is a potent hormone that results in the miniaturization of hair follicles, eventually leading to the stopping of hair growth.
Propecia tablets are film-coated for oral administration, with each tablet containing 1 mg of finasteride. It is considered as the first-line treatment for androgenetic hair loss in men. It is available only with a doctor’s prescription.
Finasteride is to be taken by mouth for up to three months before seeing a benefit from the medication. It will only work long term, which means that you have to continuously take it. If finasteride will not work for you within 12 months of use, do not continue with the treatment because it will no longer benefit you. If you stop taking finasteride, you will likely lose the hair that you have gained with 12 months that you were taking it.
Finasteride may be taken with or without a meal. The recommended dose of finasteride to treat androgenetic hair loss is one 1-mg tablet daily. Finasteride has been proven to successfully work in men between the ages of 18 and 41 who have mild to moderate hair loss of the vertex and the anterior mid-scalp area.
How long does Finasteride last?
If you are taking finasteride to grow hair, remember that it is not an immediate process. It will take from three to four months before you see any results. If you take finasteride as directed by your doctor every day, expect to see results on the third or fourth month. The full effects of finasteride can be seen in six to nine months because it takes plenty of time before new hairs are produced.
Finasteride does not always regrow the hair that you lost. In some cases, men take finasteride in order to arrest further hair loss, instead of regrowing hair. It is possible that you may not notice any improvement in your hair after taking finasteride although finasteride continues to work by preventing any additional hair loss.
Even if you take finasteride for hair growth, it is important to keep in mind that your hair will still fall out because it is part of its natural growth cycle. Hair is lost in order to be replaced by new hair. Expect to see some hairs in the shower or in your comb.
For the full results of finasteride to be noticeable, wait for at least one full year of using it on a daily basis. Skipping the pills for some days or weeks can prevent finasteride from working as effectively as it should.
Even if you do not see visible production of new hair, you should not stop taking finasteride. If you stop taking finasteride, your natural hair will go back to its natural amount and you might continue losing hair.
When used according to the instructions of your doctor, finasteride is very effective in preventing hair loss. Don’t be impatient because it takes several months before new hairs are produced.
Side effects of Finasteride
A decreased sexual ability or desire may occur when you take finasteride. In some men, finasteride may decrease the amount of semen released during sex. This is a harmless side effect but has continued in some men even after they stopped taking finasteride. Notify your doctor immediately if the side effects get worse or persist.
Tell your doctor immediately if you have any of the serious side effects: nipple discharge, lump in the breast, breast enlargement or tenderness, pain in the testicles, and inability to urinate.
An allergic reaction to finasteride is not likely, but get immediate medical attention if they occur. The symptoms of a serious allergic reaction include itching or swelling, especially of the face/tongue/throat, rash, trouble breathing, and severe dizziness.
Before taking this medication, tell your doctor if you are allergic to it, or if you have any other allergies.
Before using this medication, tell your doctor your medical history, especially of prostate cancer, liver disease, infections, and urinary problems.
Finasteride should not be used in children. Finasteride can be absorbed through the skin. If the film coating of the tablets has been broken or the tablet crushed, it should not be handled by a woman who is pregnant or planning to become pregnant. The exposure of a male fetus to finasteride may result in the development of abnormal genitals.
Finasteride is used only by adult males. A broken or crushed tablet should not be handled by a pregnant woman. It should also not be handled by a breastfeeding woman.
