Tell your doctor about other blood thinners or painkillers like ibuprofen; older age and low body weight raise bleeding risk

Sudden weakness, face drooping or speech trouble (urgent)
Purple spots on skin with fever or confusion (urgent)

Not a prescription — no dose shown. The right dose of prasugrel depends on age, weight, kidney/liver function and the condition, so MedDroid does not show a dose here. Always get your dose from a doctor or pharmacist and the leaflet inside the pack. General educational information only.

Frequently asked questions

How is it different from clopidogrel?

Prasugrel works more strongly and more reliably than clopidogrel, but with a higher bleeding risk.

Can I stop it before dental work?

Not without asking your heart doctor; stopping early after a stent can cause a dangerous clot.

Why do I also need aspirin?

Together they protect the stent better than either alone, for the period your cardiologist sets.
