Tadalafil safety, interactions and when to seek medical help
Short answer: tadalafil is a clinically studied PDE5 inhibitor, but safe use still depends on your health profile and current therapy.
The most important contraindication
Tadalafil must not be combined with nitrates for chest pain or with riociguat — the combination can dangerously lower blood pressure.
Medicines and conditions that need review
Tell your doctor/pharmacist if you take alpha-blockers, blood-pressure medicines, strong CYP3A4 inhibitors, another PDE5 inhibitor, or have heart, kidney or liver disease.
Common side effects
Official information lists headache, indigestion, back/muscle pain, flushing, nasal congestion and dizziness as possible reactions. Intensity varies between individuals.
Emergency symptoms
Seek urgent help for chest pain, an erection lasting more than four hours, a sudden change in vision or hearing, a severe allergic reaction or fainting.
Verifying the product
Do not rely only on a logo, colour or packaging photo. Check the expiry date and intact tamper evidence before use, and consult a pharmacist if in doubt.
