Yes, you can safely take Metformin if you are allergic to sulpha drugs.
It belongs to the drug class of non-sulfonylureas.
If you mean you are allergic to the antibiotic, it is sulfa (not sulpher-totally different chemical) short for sulfonomides ( a type of antibiotic) Metformin is not a sulfonomide.
A you're not allergic to sulpher, you're allergic to sulfonamides. There is a big difference. You can take metformin..
