Vidalista contains tadalafil, which is used to treat erectile dysfunction. For many people with diabetes, tadalafil can be used safely, but whether it's appropriate depends on your overall health and the medications you take. In general: Yes, it is often prescribed for people with diabetes. In fact, erectile dysfunction is more common in people with diabetes, and tadalafil has been shown to be effective for many of them. It does not treat diabetes itself. Good blood sugar control remains important because high glucose levels can damage blood vessels and nerves involved in erections. The main safety concern is interactions with other medications. Vidalista should not take tadalafil if you use nitrate medications (such as nitroglycerin for chest pain), because the combination can cause a dangerous drop in blood pressure. Use caution if you have significant heart disease, severe liver disease, severe kidney disease, or very low blood pressure. Your healthcare provider may recommend a lower dose or advise against its use depending on your situation. Common side effects include headache, flushing, indigestion, nasal congestion, back pain, and muscle aches. Seek immediate medical attention for chest pain, sudden vision or hearing loss, or an erection lasting more than 4 hours. If you have diabetes and erectile dysfunction, it's also worth making sure your diabetes, blood pressure, and cholesterol are well managed, since improving these can improve erectile function over time.
