Whatever medicine you take, you are bound to experience some kind of side effects. What really matters is the severity of the effect on your body. While some side effects are common and fade away with the passage of time, some others are very serious and call for immediate medical attention. Finasteride under the brand name Proscar and Propecia also shows some side effects. In fact, most people receive Finasteride well with fewer complaints regarding its side effects.

Proscar has been studied and analyzed in detail in various clinical trials. A lot of patients suffering from Benign Prostatic Hyperplasia (BPH) or enlarged prostate condition have been evaluated under these trails. During the studies, side effects occurring in those patients by taking Proscar are always documented and equated with the side effects shown by a similar group of patients not using the medication. The most common side effects of Proscar found from these trials include:

• Decreased libido that means lower sexual drive or urge.
• Erectile dysfunction or impotence where it is difficult to attain and sustain an erection of the penis.
• Abnormal ejaculation that also includes reduced amount of ejaculation.
• Breast enlargement
• Difficulty in having an orgasm
• Swelling in your hands or feet
• Headache
• Dizziness, weakness
• Pain in the testicles
• Swelling or tenderness in your breasts
• Runny nose
• Skin rash

A few patients have reported of experiencing some serious side effects of Proscar (Finasteride). If you have symptoms of allergic reaction such as hives, difficulty breathing, swelling of face, lips, tongue or throat, you must discontinue the medicine straightway and seek emergency medical help. Some other severe side effects may include breast pain, breast lumps, nipple discharge and other breast changes. These are symptoms of male breast cancer and must be informed to your doctor without any delay.

It is out of the question for your physician to know whether you’ll develop sexual side effects before starting the treatment of Proscar. It is also difficult to know whether side effects like erectile dysfunction or decreased libido are really induced by Proscar or any other condition. Nevertheless, you must consult your doctor and seek his/her advice if you develop sexual side effects by using Proscar (Finasteride). He or she may prescribe you certain alternative medicines such as ED drug to deal with these side effects. If the severity of effects persists, your healthcare provider may direct you to alter the dosage of Proscar or try out another medication to treat your BPH condition.
