PDE5 inhibitor
Tadalafil with statins (atorvastatin, rosuvastatin, simvastatin)
Statins are among the most widely prescribed chronic medications, often used alongside many other agents including Tadalafil (Tadalafil). The combination at 20mg, 2.5mg, 5mg, 10mg is generally safe, but a small number of statin-specific interactions matter — particularly for simvastatin, which shares CYP3A4 metabolism with several common medications.
How Tadalafil interacts with statins
Statins differ in their metabolic pathways: simvastatin and atorvastatin go through CYP3A4 most heavily; rosuvastatin and pravastatin take other routes and have fewer drug interactions. If Tadalafil acts on CYP3A4, the combination with simvastatin or atorvastatin can raise statin levels and increase muscle-related side effects. Tadalafil selectively inhibits PDE5, the enzyme responsible for breaking down cyclic guanosine monophosphate in the corpus cavernosum and other vascular smooth muscle.
Practical guidance
According to the prescribing information for Tadalafil, anyone on a statin should mention it before starting Tadalafil at 20mg, 2.5mg, 5mg, 10mg. The prescriber may switch the statin (e.g. from simvastatin to rosuvastatin) or adjust the statin dose during Tadalafil use. Persistent muscle pain, weakness or dark urine on the combination warrants prompt evaluation.
Frequently asked questions
Can I take Tadalafil with my statin? ▾
For most users at 20mg, 2.5mg, 5mg, 10mg, yes — particularly with rosuvastatin or pravastatin which have minimal interactions with Tadalafil. Simvastatin and atorvastatin combinations may need a dose review by the prescriber to avoid amplified statin effects.
Will Tadalafil cause muscle pain with my statin? ▾
Muscle pain is the most common statin side effect and can be amplified when combined with medications that raise statin plasma levels. Persistent or new muscle pain on Tadalafil at 20mg, 2.5mg, 5mg, 10mg should be reported promptly so the prescriber can review the combination.
