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.

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, diarrhoea.

3. A stat capillary glucose check is important.

4. Itchy skin rash can be taken care with antihistamines such as cetirizine 10mg or levocet 5mg. People with diabetes can get a fungal skin rash that is varaibly itchy and not much red, for which antifungal creams are required. See your doctor if the antihistamine tabelts do not help.

Best Wishes.
