I looked at the The Mastocytosis Society's page for the ER and what drugs to administer with caution. Alcohol solutions were on that list.
After looking at the ingredients on these two meds I noticed Sorbitol and Malitol both of which are sugar alcohols. I'm not real sure if that's the same thing as an "alcohol solution" but we are going to stop using them just in case. Besides from what I understand children under 6 shouldn't be taking this medicine anyways. We will use this alcohol free version of Delsym instead. This was originally what our pediatrician prescribed a few years ago when Titan was little. Somehow letting husband man wander in the store to pick up medicine these other few have made it into our cupboards.
*UPDATE: I wanted to add this update that I found in my search about cough suppressants. In a recent post I described the triggers in these cough suppressants to avoid as I found from a list of common mast cell granulation triggers. If you are a masto momma you definitely need to have this list printed out and placed in a bag for your child to have on hand at all times (or at least have access to this webpage when you need help).
