    Red dye
    tdavidson001 posted:
    I am allergic to dispersed Red 17 and apparently any red dye.
    Because of this I am trying to be careful with any food and/or medications that might have red dye in them.

    I also have hypo-thyroidism and my levothyroxine is coated with purple which probably contains red dye.

    I called my pharmacy and they don't seem to have a source where they can get a dye free equivalent.

    I may have to go to a different pharmacy.

    Does anyone know of a manufacture that has what I'm looking for.

    I would recommend contacting your prescibing doctor. I believe there are a few manufacturers. I have read that different strengths have different colorings. Your doctor may be able to prescibe a different manufacturer and/or a different dose/quantity to get you what you need.

    Take care. Debbie
