Should I be checking with a pharmacist before taking common cold or hay fever medicine alongside Elvanse?

So over the counter medication is generally safe, BUT you should always check with a pharmacist or your clincian if you are in doubt or if its something you havent taken before. It's important to note that some medication will impact the absorption (how quickly the medication gets into your body) and the metabolism (how quickly the medication is processed by your body) changed as a result of the stimulant medication.
