Patients with insurance coverage of one of the main study partners. (Horizon, Independence Blue Cross, Aetna, Keystone Mercy, and HealthFirst) (Please note, patients who are prescribed the anti-platelet Effient® (prasugrel) will not be given a GlowCap to use for this medication due to specific guidance about pill maintenance. The package insert for Effient® (prasugrel) (http://pi.lilly.com/us/effientppi.pdf) indicates the medication should remain in the original bottle, it should be kept at room temperature between 59°F to 86°F (15°C to 30°C) and the container should be closed tightly with the gray cylinder inside and be protected from moisture. This does not necessarily exclude these patients from participation in the study, they will still be eligible as long as they have been prescribed at least 2 of the remaining 3 medications being observed in this study. Also, those who are taking an anti-platelet other than Effient® (prasugrel) (ie, Plavix) will be given a GlowCap to use to take that medication.
