Side Effects & Reactions

Finasteride (Propecia) For Hair Loss

Like any other medication, Finasteride can come with several side effects depending on the individual. This is why it is important to know just what could happen should Finasteride react with your body.

Any reactions and effects are generally thought to be reversible but there may be some persistent side effects too. The true rate of long-term side effects is not clearly known.

You should read this information along with the information leaflet that is provided with your medication. If you are concerned by these side effects, then you are advised to discuss this with your practitioner and consider alternative hair loss treatments.

Who Should Use Propecia

FDA-approved for men only, Propecia is best used for men experiencing crown thinning or baldness. Dr. Matthew Lopresti of Leonard Hair Transplant Associates explains that Propecia is, typically the first-line therapy in nearly all men with crown thinning or baldness. He specifically notes that Propecia doesnt necessarily target the frontal areas, so those with a receding hairline may not see results.

Propecia can, and sometimes should be used in tandem with other preventative hair loss treatments, such as shampoos and other topical treatments.

Meanwhile, it is not recommended for women of childbearing capacity because of the potential for fetal birth defects. It is absolutely not recommended for any woman of childbearing age, whether she plans to be pregnant or not, Dr. Sieber says. The drug does cause fetal malformations or abnormalities and can cause loss of a fetus, so it is recommended to be avoided completely in any woman of childbearing age.

However, women who experienced hair loss after menopause has found success in using Propecia.

What Should I Tell My Healthcare Provider Before Taking Finasteride

Before taking finasteride, tell your healthcare provider if you:

  • have any other medical conditions, including problems with your prostate or liver
  • Tell your healthcare provider about all the medicines you take, including prescription and nonprescription medicines, vitamins, and herbal supplements. Know the medicines you take. Keep a list of them to show your healthcare provider and pharmacist when you get a new medicine.

Can Finasteride Regrow A Receding Hairline

So, does finasteride regrow hair? Since hair loss can vary in severity from one man to another, theres no precise amount of hair that finasteride will help to protect or regrow for everyone.

As a general rule, its best to think of finasteride as a form of protection against further hair loss, and not as a guaranteed way to regrow hair youve already lost.

However, almost all scientific research shows that finasteride produces a reduction in hair loss and, for many men, improvements in hair growth.

For example, in a study published in the late 1990s, 66 percent of men with hair loss who used finasteride experienced improvements in hair growth over the course of two years, compared to just seven percent of men who used a non-therapeutic placebo.

In the same study, 83 percent of men who used finasteride showed no progression of hair loss over the two-year study period.

Now, does this mean that finasteride will completely restore your hairline? Not necessarily, as a variety of factors all play a role in hair loss.

If youve had a receding hairline for some time, or if youve already lost a lot of hair around your hairline, finasteride may not completely restore it.

However, using finasteride could cause some amount of hair regrowth in the areas of your scalp where youve only recently started to notice thinning and recession.

Why Is The 1mg Finasteride Tablet Used For Hair Loss

How Much Finasteride For Hair Loss

Dose-ranging studies were conducted in 1999 to help verify which dose of Finasteride is the best choice for male pattern hair loss.

In these studies, men were given either 0.1mg, 0.2mg, 1mg, or 5mg of Finasteride daily, or a placebo, and then their hair counts, self-reports, and clinical assessments were conducted by researchers.

The two lower doses of 0.1mg and 0.2mg were way less effective than the two higher doses, with the 0.1mg dose being about the same as the placebo .But, the two higher strengths of 1mg and 5mg were much better at improving hair counts, self-reports, and visual hair inspections.

The thing is, both the 1mg dose and the 5mg dose gave similar results, leading researchers to conclude that the 1mg dose of Finasteride is the optimal strength to prescribe for male pattern hair loss.

Important: if you develop any pain or lumps in your breast area, or any discharge from your nipples, you should tell your doctor. This is because there have been a few rare reports of breast cancer in men taking finasteride.

In addition, there have been reports of depression in men taking finasteride, and in rare cases, thoughts of self-harming. If you develop any signs of depression whilst being treated with finasteride, stop taking it and make an appointment to see your doctor.

If you experience any other symptoms which you think may be due to the tablets, speak with your doctor or pharmacist for further advice.

Finasteride For Womens Hair Loss

Propecia is not approved by the FDA for use in women and we will not prescribe it for our female patients. Considering its effectiveness for use in men, one would assume it would also work for women, assuming that their hair loss is caused by the shrinking of DHT-sensitive hair follicles. However this drug is a category X and therefore has never gained FDA clearance for use in women.

If your hair loss is determined to be female pattern baldness, your physician can recommend over-the-counter minoxidil or other prescribe medication for you though it will not be finasteride. There are other medications intended for completely different purposes that are also anti-androgens and tend to block the production or absorption of DHT.

Studies have been conducted on women and dosages have been experimented with. For example, a study conducted from 2007 to 2011 observed 256 patients diagnosed with female pattern hair loss who took 5mg of finasteride for the specific purpose of studying adverse effects.

Its very important to note that women who are pregnant, or attempting to become pregnant should not, under any circumstances, take finasteride. Propecia is considered a Category X drug for pregnancy risk, meaning that theres reason to believe the medication causes birth defects. In this case, external genitalia abnormalities in a male fetus were reported in a study performed on animals.

Getting The Most From Your Treatment

Does finasteride stop hair loss long term?
  • Each time you collect a new supply of tablets from your pharmacy, make sure they look to be the same as you have had before. This is because there is a high-dose brand of finasteride tablet available for the treatment of a different condition. If you are unsure that you have the correct tablets, ask your pharmacist to check for you.
  • Your hair growth may start to improve within a few months, although it can take up to a year or so for you to notice the full benefit. You will need to continue treatment to maintain this effect, as the balding process returns when you stop.
  • Finasteride may cause harm to an unborn baby. Because of this, women who are pregnant should not handle the tablets. Also, very small amounts of finasteride will be in your semen while you are taking this medicine. If you need further advice about this, speak with your pharmacist or doctor.
  • If you are having an operation or any medical treatment, tell the person carrying out the treatment that you are taking finasteride. This is because finasteride can interfere with a blood test used to detect prostate cancer, so you must tell your doctor about taking finasteride if you need this test.

Combine It With Other Treatments

There is nothing to stop you from combining finasteride with minoxidil, the other FDA-approved treatment for male baldness. These two drugs do not interact, and results will typically be superior to either treatment on its own.

There are also various natural compounds you can try, some of which will be oral and others topical. Some of the most popular topical treatments are caffeine, castor oil, and various essential oils .

How To Take Finasteride

Finasteride For Hair Loss

For hair loss, you should take one tablet of finasteride daily.

You should not crush or break finasteride and you should swallow the tablet whole with water. This is because finasteride can be absorbed through the skin and can potentially cause birth defects if a pregnant woman comes into contact with it.

You can take finasteride on an empty stomach, or after a meal. There is no best time to take finasteride, but you should try to take it at the same time each day to help you get into a routine. This reduces the chances of forgetting to take a dose.

Missing a dose of finasteride occasionally is unlikely to affect your hair growth. However, finasteride has a short half-life which means that it exits the body quickly. Missing frequent doses can negatively impact results. If you do miss a dose of finasteride, do not take an extra tablet to make up for the missed dose. Continue to take your tablets as normal when it is time to take your next dose.

Tip: You can set a reminder on your phone to help you remember to take your tablets. Alternatively, you can leave your tablets by your toothbrush to remind yourself that you need to take a tablet.
