I'm on an AP and donate every two months. There's a list of drugs they don't accept but APs aren't on the list. Years ago....about 20 they wouldn't accept me but the Red Cross now accepts most preventive meds as OK. I don't even have to keep track of my donations they call me when it's close and I make the appointment and they even send a reminder email. There's a huge need for blood. I'm O+ so everyone except the negative can receive my blood. It gives me a great feeling of purpose.
