[|Human|] Hello, I ve got a question about a skin rash . My husband has diabetes and has been taking metformin for 3 years. In the last two days he d developed a skin rash that itches very much. It usually starts in the evening for him. He has not taken his metformin today. He also has a stomach cramps, diarrhoea and is unable to eat. He had earlier developed the same type of allergy to chloroquinone. Thank you for your reply in advance.
[|AI|]  Hello,1. Please ensure there is no gastroenteritis (bacterial) with a stool routine/ culture studies. If there is fever, he will need a complete blood count, CRP, liver function tests. 2. Metformin itself can cause cramps, diarrhea.3. A stat capillary glucose check is important.4. Itchy skin rash can be taken care with antihistamines such as cetirizine 10 mg or Exocet 5 mg. People with diabetes can get a fungal skin rash that is variably itchy and not much red, for which antifungal creams are required. See your doctor if the antihistamine tablets do not help. Best Wishes.
