Tadalista 10 mg contains tadalafil, a PDE5 inhibitor used for erectile dysfunction. Like all medicines, it can cause side effects, though not everyone experiences them. Common side effects These are usually mild and temporary: Headache Flushing (warmth or redness of face/neck) Nasal congestion or runny nose Indigestion or heartburn Back pain or muscle aches Dizziness Mild vision changes (slight blur or color tint in some cases) Less common side effects Fast or irregular heartbeat Dry mouth Fatigue Stomach discomfort Serious side effects (seek medical help immediately) Priapism (painful erection lasting more than 4 hours) Sudden loss of vision in one or both eyes Sudden hearing loss or ringing in ears Chest pain or severe shortness of breath Severe drop in blood pressure (especially if combined with nitrates or alcohol) Important safety note Tadalista 10 mg should not be taken with nitrate medications (often used for chest pain), as this combination can cause a dangerous fall in blood pressure. Caution is also needed in people with heart disease, liver/kidney problems, or those taking alpha-blockers. If side effects are mild and persistent, adjusting the dose under a doctor’s guidance is often enough.
