No solutions, I'm afraid, but sympathy, as my daughter is lactose intolerant. Most medication contains lactose. She was told she couldn't possibly be asthmatic as medication seemed to make her breathing worse! And making sure she got lactose free medication for high blood pressure was an up hill struggle when she had pre-eclampsia.....
I saw a well qualified nutritionist who helped both my daughter and me find out what our intolerances are, though testing is never completely accurate. If you are allergic, rather than intolerant or sensitive, your doctor can refer you to a specialist. Other than that, email Dr Currie for help.
