Viagra is a drug that is prescribed to cure erectile dysfunction
Viagra is a drug that is prescribed to cure erectile dysfunction. This drug should only be used by men who have impotency problems and only after visiting a doctor. Just like other drugs, Viagra also has side effects that appear differently to different individuals. Some of its common side effects include facial flushing, headache, upset stomach and nausea among others. Other users have reported changes in colour vision and blurred vision. Viagra should be used strictly as prescribed by the doctor because when it is overused it can lead to very serious side effects.
