We have a whole bag of OTC meds that we take on every cruise. Such as cough meds, allergy meds, pain meds, anti-diarrhea meds, meclizine, mole skin, all types of band aids, cortisone cream, antacids, neosporin, etc. Additionally we bring an extra week of our prescription medicine. It may seem a bit extreme to take all of this on vacation but there have been times when the need arose and we were glad to have them. Also we have helped other passengers who needed it.
