Both 5mg and 1mg Propecia (finasteride) carry similar side effects, but their frequency differs. The 5mg dose, often used off-label for conditions other than hair loss, presents a higher risk of experiencing these side effects.
Sexual side effects, including decreased libido, erectile dysfunction, and ejaculation disorders, are the most commonly reported. These occur more frequently with the 5mg dose. Studies suggest a roughly 2-4% incidence at the 1mg dose, rising with the higher dose.
Gynecomastia (breast enlargement) is another potential side effect, though rare. The 1mg dose significantly reduces this risk compared to the 5mg dose.
Other potential side effects include depression, anxiety, and skin reactions. While infrequent, they warrant consideration. Again, the higher dose increases the probability.
Recommendation: For hair loss treatment, the FDA-approved 1mg dose offers a preferable risk-benefit profile. The advantages of the 5mg dose’s potentially stronger effects are often outweighed by the increased likelihood of side effects. Always discuss potential risks with your doctor before starting any medication.
