As with any drug taken internally, there are a number of side effects that you should be aware of before you take Propecia. The active ingredient in Propecia – Finasteride – has a number of qualities which could change the interactions of normal chemicals within the human body.
As such, we recommend that you familiarize yourself with the possible side effects of Propecia before you go on a course of the drug, so that you can report back to your doctor with anything that does develop.
Minor Side Effects
Minor side effect of Propecia are those which are considered to be more annoying or bothersome than dangerous. It is estimated that up to 15% of Propecia users will suffer from some variation of one of the following side effects whilst they are using the drug:
Decreased Ejaculation Volume
As you can see, most of these minor side effects are centered around the sexual functioning and performance area. This is because of the areas in the body which the active ingredient of Propecia targets. Those two areas, obviously, are the hair area – and the genitalia area.
Major Side Effect
Thankfully, despite having a number of fairly annoying minor side effects, Propecia has very little potential to cause long term, dangerous harm to the body. This means that Propecia use is safe in the long term. There are two exceptions to this. The first involves complications arising from the minor side effects. In some cases, people have reported that the minor side effects have continued well in to the future – even when the course of Propecia has ended. In December of 2008, a Swedish study found that erectile dysfunction can continue “indefinitely” as a result of Propecia use. Hence – it was recommended that anyone who begins to suffer from erection difficulties whilst on the drug should consult their doctor as soon as possible to ensure no long term harm. The other exception of the safety of Propecia is in women. The active ingredient should never be consumed by females – and in many cases should never even be handled by a female. This is because it is possible for the drug to pass in to breast milk and even breast tissue – and the long term / prenatal effects of this are yet to be evaluated.
