The highest dose of Cialis available is 20 mg – Super Vidalista 20 mg. This is the highest dose advised for treating erectile dysfunction (ED) in men. While some may consider taking larger amounts, such as 40 mg, this is neither safe nor effective. Increasing the dose beyond 20 mg may result in more severe side effects without significantly enhancing erectile function. Headaches, flushing, and dizziness are common side effects of Cialis, but taking a greater dose increases the chance of significant consequences such as priapism, a painful erection that lasts more than four hours. Cialis is available in several strengths, including 2.5 mg, 5 mg, 10 mg, and 20 mg. Doctors generally start patients on a lesser dose to check tolerance and effectiveness. If the lower doses do not work well, a healthcare provider can increase the dosage to a maximum of 20 mg. It is critical to follow your doctor’s instructions and not exceed the recommended quantity. If you believe your current dosage is ineffective, visit your healthcare practitioner about alternate treatments or changes rather than self-medicating with bigger doses.
