What could cause generalized body itching after initiating new vitamin supplements, and what are the appropriate next steps if the symptoms persist despite treatment with antihistamines?
This itching could be an allergic reaction to an active ingredient, dye, or filler in the supplement. Sometimes, high doses of certain nutrients, like niacin, can also trigger itching. Since antihistamines haven't provided relief, I recommend temporarily stopping the supplement and consulting your healthcare provider. They can help safely identify the exact cause. Please seek immediate medical care if you experience any swelling, hives, or difficulty breathing.
