Tadalafil, or Cialis, is used for erections and sometimes prostate-related urinary symptoms. People also use it for workout pumps, but that does not make it a muscle builder. Its effects last longer than many other erection medicines. Headache, flushing, back pain and low blood pressure can occur; nitrates and riociguat are dangerous combinations.

Research & sources
Evidence
Official labeling supports its prescription indications. Fitness-community discussion about pumps and blood flow is not evidence of muscle gain or universal cardiovascular benefit.
Interactions & monitoring
Headache, flushing, nasal congestion, indigestion, back or muscle pain and low blood pressure; dangerous nitrate interaction; rare prolonged erection, hearing loss or vision problems.
Blood pressure, cardiovascular history, interacting nitrates or alpha-blockers, kidney/liver factors and urgent assessment for severe visual, hearing or prolonged-erection symptoms.
Medical context
Approved under product-specific labeling for erectile dysfunction, urinary symptoms from benign prostatic hyperplasia and pulmonary arterial hypertension; it is not a muscle-building medicine.
