Since I have no known allergies please excuse my limited knowledge here, but I have a couple of ideas. Maybe tell them your specific allergies and see if they give a straight answer. Also I am unsure what product you want, yet tests sometimes reveal added or missing items not on the label. With severe allergies it looks risky to work in gray areas. If this involves Indian pharma a trusted rep might give a real answer.
I like to get the cleanest medications I can within my budget because I react to some ingredients. I often reach out to US makers to learn the exact composition. All but one answered my calls or emails, though one gave wrong details and that caused a reaction. American micronized progesterone uses peanut oil. When I contacted several producers of items sold in India, only one of four replied and called the information confidential. That seems odd since I am not asking for any secret formula. Do others with allergies have suggestions for getting foreign companies to answer? Is this kind of data not shared with patients outside the US?
