The main ingredient of vidalista is Tadalafil, which is an active vasodilator. This increases the blood flow and enables the erection to last longer. If you are allergic to Tadalafil, you should not use this medication. Other than that, you may also have some side effects. Some common ones are nausea, vomiting, headache, dizziness, indigestion, rash, and flushing. You should report these symptoms to your doctor immediately.

 While vidalista 20 is safe for most adults, it is not recommended for children. In addition, it should be taken only as advised by your physician. Also, do not take Vidalista if you are taking any other drugs. Taking other erectile dysfunction medications simultaneously could result in unwanted side effects.
