Men with diabetes can take Vidalista 80, but only under medical supervision. Tadalafil is generally effective in diabetic patients, but higher doses like 80 mg should be used with caution due to the increased risk of side effects. Men with diabetes should never self-prescribe Vidalista 80. While it can be effective, the high dose increases the chance of side effects. Always consult a healthcare provider to determine the safest and most effective ED treatment for your condition. Vidalista 80 is usually reserved for cases where lower doses are ineffective and the patient has no major health complications.
