Sorry, for the delay in answering. The answer to your question is yes. I gave my son one drop of Iodine two days in a row. He uses inhaler and Allegra. About ten days ago those two days were really bad for him. He came down with a severe headache in between his eyes and then the pain traveled in other areas, shoulders, back spine etc. I got so afraid. I massaged his back and head for hours and it made him feel good, but next day we had to take him to a doctor. The doctor could not do anything at all. He just came home and took more drugs like sudafed etc. I feel terrible now.
He is fine now, but allergies just do not go away.
I have to get him to stop the drugs.
I hope you do not have any reactions with mixing any meds.
