Tadalafil 40mg should not be taken daily unless specifically prescribed and monitored by a qualified healthcare professional. For erectile dysfunction, 40mg is higher than the usual approved daily or on-demand doses, and taking it regularly may increase the risk of side effects such as headache, dizziness, flushing, indigestion, and low blood pressure. Tadalafil 40mg can also interact dangerously with nitrate medicines and may require caution with certain blood-pressure medications. Anyone considering regular tadalafil use should discuss their health history and current medicines with a doctor.
