[|Human|] What is a good alternative to metformin if you are experiencing diarrhea and are starting to have allergic reactions such as rash, hives swelling of lips. Could not relate allergy to any one food or drink and reactions are not always the same. Sometimes may be hives on legs and buttock, other times may be lip swelling or swelling on head and back of neck. Use zantac and loratidine some times with good relief, other times with minimal relief and will add benadryl.
[|AI|]  HI, thanks for using Chat Doctor You should consider formal allergy blood tests to make sure there is no other source of your allergic reaction. Allergy tests can be done for food, Chat Doctor. If it is related to the metformin you should discontinue it. Diarrhea is a common complication of metformin, but the others are not common, this is why other causes should be ruled out. There are other oral or injectable medications that can be used but none of them would be in the family of metformin. I hope this helps
