Not medical advice

The product descriptions, dosage notes, usage guidance and answers published on this website are general information. They are not a diagnosis, a prescription or a recommendation for your individual situation. Always speak to a licensed healthcare professional before starting, stopping or changing any medication.

Individual results vary

How a medication works depends on your health, age, other medication you take and many other factors. Information about typical onset times, durations and effects describes averages, not guarantees.

Interactions and safety

Some medications interact dangerously with others, particularly nitrates, certain blood pressure drugs and some antibiotics and antifungals. Never combine treatments without professional advice, and seek urgent medical help if you experience chest pain, sudden vision or hearing loss, or an erection lasting more than four hours.

Accuracy
