The standard Propecia dose (1mg of finasteride daily) is generally well-tolerated, but some men experience side effects. These are usually mild and temporary, disappearing once treatment stops. However, understanding potential issues is key.
Sexual Side Effects
The most commonly reported side effects are related to sexual function. These include decreased libido, erectile dysfunction, and ejaculation disorders. The frequency varies, but studies suggest these occur in a small percentage of users. Importantly, these side effects are usually mild and often resolve upon discontinuation of the medication. If these persist or are bothersome, consult your doctor immediately.
Other Possible Side Effects
Beyond sexual side effects, some men report less common issues such as gynecomastia (breast enlargement), depression, and anxiety. While rare, these deserve attention. Again, these are usually mild and resolve upon stopping the medication. However, any significant or persistent side effects warrant a conversation with your physician.
Severity and Reporting
The severity of side effects can vary greatly among individuals. Some men experience no noticeable side effects, while others experience more pronounced symptoms. Open communication with your doctor is crucial. If you experience any concerning side effects, report them promptly. Early intervention often facilitates better management.
