Propecia, containing finasteride, can cause side effects, though they aren’t common for all users. The most frequently reported include decreased libido, erectile dysfunction, and ejaculation problems. These typically subside after stopping the medication.
Sexual Side Effects
Studies show these sexual side effects affect approximately 2% of users. However, a small percentage experience persistent symptoms even after discontinuation. Open communication with your doctor is key. Discuss any changes in sexual function; they can help manage potential side effects or suggest alternative treatments.
Other Potential Side Effects
Less common side effects include breast tenderness or enlargement (gynecomastia), and depression. While rare, these warrant immediate medical attention. Propecia can also rarely cause allergic reactions, such as skin rashes or itching.
Long-Term Risks
Long-term use of Propecia has been linked in some cases to persistent sexual dysfunction, even after treatment cessation. The exact mechanisms and prevalence are still being studied. Regular check-ups with your doctor are recommended to monitor your overall health and address any concerns.
Important Considerations Before Starting Propecia
Inform your doctor about your complete medical history, including any existing health conditions or medications you take. This helps assess potential risks and interactions. Pregnancy is a strict contraindication. Finasteride can harm a developing fetus. Women of childbearing age should not handle crushed or broken tablets. If pregnancy occurs while taking Propecia, consult a doctor immediately.
