Question: I would like some advice as I have been taking the Propecia for a month now and have experienced some side effects such as a slight decrease in libido and semen not being as thick as it was previously. I am a happily married with children and have not in the past had any issues with libido.
Are these side effects something that I should be concerned about and therefore stop taking this drug or are these minor side effects that should decease after my body becomes used to the drug? My real concern and worry is, will taking Propecia have a damaging affect sperm morphology and limit my ability to have more children?
Answer: If you are a Belgravia Centre client we would generally advise you to consult with your hair loss specialist straight away if you believe you are experiencing these kinds of side effects. Generally, we would advise anyone in such circumstances to stop taking this medication.
The side effects of Propecia, such as the ones you mentioned, are possible although the incidence rate is considered rare (less than 2%).
In the clinical studies that proved Propecia (a popular brand name for finasteride 1mg) to be safe and effective for the treatment of hair loss in men, all side effects disappeared in men who stopped the treatment, and by the end of the study, the incidence of those side effects was less than 0.3% in men who continued this type of hair loss treatment. Decreased semen volume may equate to decreased sperm count, but this effect is believed to reverse once the medication has left the body.
Propecia should not be used when attempting to conceive, which is why we advise users to stop a week before trying for a baby. Propecia has a very short half-life, which means is will be out of your system seven days once you stop taking it. Most of the men involved in the clinical trials of Propecia were of childbearing age (18-41) and there have been no reports of fertility issues among them.
We recommend you discuss your concerns with whoever dispensed your hair loss medication. Should you wish to consider a minoxidil-only hair loss treatment course, this is an alternative option and one of our specialists would be happy to discuss this with you.
