Hello and Welcome to ‘Ask A Doctor’ service.
I have reviewed your query and here is my advice.
Effient(
prasugrel) is a medicine used to prevent from forming harmful
blood clots in a patient. In this case in a patient that had a
heart attack and required stents.
This medicine is used from six to one year usually after the heart attack, because of the high risk of bleeding that has the patient.
It's used for more than one year only in patients that have high risk for blood clotting.
Some of the new guidelines suggest the use of Effient for three months, because of the high risk of bleeding in some patients.
Probably your husband has been using Effiel in combination with
acetylsalicylic acid in low dosage.
He has to continue using acetylsalicylic acid in low dosage, which also has the antiagregant effect and protects him from blood clotting.
Hope I have answered your query.
Let me know if I can assist you further
