Summary

How can people with allergies get detailed excipient lists from international drug manufacturers?

The thread describes repeated attempts to contact makers for full ingredient details on medications like progesterone and metformin due to personal reactions. US firms mostly reply though accuracy varies, while Indian producers often decline citing confidentiality even after allergy explanations. Users note that pharmacists and doctors rarely know the specifics and redirect inquiries back to manufacturers. One participant found a database useful for comparing brands and switching to stop side effects.

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?

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 started by requesting a full ingredient list the way US databases list them, and that is when they called it confidential. I followed up by describing my allergies and asking what oil or alternative they use, but got no reply. Even with US firms I usually have to mention allergies first or they dismiss the question or say to ask my doctor who never has time. When I get medications the pharmacist also does not know the components and tells me to call the maker. It is frustrating because many ingredients come from different sources. A starch could be corn, tapioca or wheat so the label alone does not tell you until you ask. My allergies are not severe enough to be life threatening but I still waste money on items that make me ill. I wondered if other countries handle this differently. Many hormones in the US are made with seed oil including at compounding pharmacies.

I questioned several support staff but they insisted it couldn't be determined. Up to that point i'd never dealt with sensitivities of any kind then out of nowhere my pulse sped up sleep vanished and a faint irritation appeared. Pinpointing the trigger took two full years plus a holistic doctor and everything traced back to what i was eating.

A database started by Canadians let me check that the metformin brand I took for two months had a different set of inactive ingredients than other versions. Switching brands ended the itching.
