Q: What is allergy to sulpha and why does it happen? What precautions should be taken to prevent an accident?

A:Allergy to any drug such as sulphonamides can develop at any time. The only precaution one can take is to avoid the use of a drug that causes allergy. There is no other way. If allergy develops for any reason whatsoever, one can take anti-allergic products such as Loridin Rapitabs (1 tablet once daily).
