Vidalista CT 20 can cause headaches as a common side effect. This medication contains tadalafil 20 mg combined with dapoxetine, giving it a dual effect: tadalafil helps with erectile dysfunction (ED), while dapoxetine helps delay ***** in cases of premature ***** (PE). Why headaches occur: Tadalafil relaxes blood vessels, which can cause temporary changes in blood flow and pressure, leading to mild to moderate headaches. Dapoxetine can also contribute to headaches as part of its effects on serotonin levels in the brain. Other possible side effects of Vidalista CT 20: Flushing (redness of the face) Dizziness or lightheadedness Upset stomach or nausea Nasal congestion Mild vision changes Safety notes: Should not be used with nitrate medications (for chest pain) due to the risk of dangerous blood pressure drops. Caution is needed if combined with blood pressure medications or alpha-blockers. Usually taken 1–3 hours before ***** activity, under medical supervision. In most men, headaches are temporary and mild, but if severe or persistent, a healthcare provider should be consulted.
