If you suffer from dust allergy, or associated allergies like pet dander and pollen, it’s essential to keep an emergency supply of antihistamines with you. On a number of occasions I’ve spent the night away only to arrive at a friends house and they’ve just got a new cat, or they just don’t dust their house properly and suddenly I’ve got that familiar itch in the throat and soreness in the eyes that means a reaction is coming on. You can cut off three or four tablets from your regular medication and store them in your wallet so you’re not caught out. As well as antihistamines, do this for decongestant tablets as well so you can relive sinus pressure whenever you feel it coming on. Now I’ve always got a regular supply to hand, and won’t be caught out looking for a pharmacist if I need them.
