Tadalafil offers two options: an as-needed dose taken about 30 minutes before intimacy, with effects lasting up to 36 hours, or a lower daily dose taken at the same time each day for continuous readiness. Follow the specific dosing instructions from your prescribing clinician and do not exceed one dose in 24 hours.
The most common side effects are headache, back pain, muscle pain, indigestion, facial flushing, stuffy nose, and limb pain. Most side effects are mild and temporary. Contact your provider immediately for severe reactions or an erection lasting more than 4 hours.

How It Helps
How Tadalafil Works to Treat ED.
Blocks PDE5
PDE5 is an enzyme that limits blood flow. Tadalafil inhibits its production, allowing blood to flow more freely to the penis.
Improves Blood Flow
Better blood flow means stronger, harder erections that last long enough to satisfy you and your partner.
Lasts Up to 36 Hours
Take as needed 30 minutes before intimacy — effects last up to 36 hours. Or take a low daily dose for continuous readiness.
