Bigfun Jelly Mint Cool is used to treat erectile dysfunction (inability to maintain erection for intercourse) in men. It relaxes the blood vessels in the penis, thereby increasing blood flow on sexual stimulation. This helps to achieve and maintain a hard, erect penis suitable for sexual activity. Bigfun Jelly Mint Cool should be used only under medical supervision as prescribed. Use it exactly as advised by your doctor. It does not affect fertility or sperm count. But, it may have side effects like flushing (sense of warmth in the face, ears, neck, and trunk), headache, and blurred vision. It can be dangerous if used along with medicines called nitrates (often given for chest pain). Do not use this medicine if you have severe heart or liver problems, if you have recently had a stroke or heart attack or if you have low blood pressure. Let your doctor know if you suffer from these or any other health problems before taking it. You should not drive if this medicine makes you feel dizzy. Avoid drinking alcohol while taking this medicine as it can lead to side effects.
