HElp, my mom has MRSA and they want her to take Rifampin but the prescription is $140.00 at walmart and she has no insurance, is there anything else that will help? is there a generic or is this the generic? she went to doc on saturday and is suppose to go back the 13th but am really scared of what will happen if she doesnt get the medicine.... tried to find some agency that will help with prescriptions, she gets SS now but is only 62 so no help with insurance... any ideas would be appreciated. I cant help her until Friday payday... am at a loss but am scared because the huge red sores are worse than they were saturda
