My grandpa takes 300mg gabapentin and was prescribed 600mg instead to help more. He decided to go back down to 300mg but was filling the 600mg in between. He uses Walgreens and the pharmacist called his doctor to see which one he should be on he said 300mg and now he has to wait 30 days in between fills no more filling early. He now has run out and has about 6 days before he can fill. My question is would he be able to remove the 600mg from Walgreens and fill it somewhere else or would he get in trouble. Thank you in advance for your help.
