Know Which Medication Is Right for Your Seasonal Allergies

An allergy is your body’s reaction to an otherwise innocent substance that it has identified as an invader. If you have allergies and encounter a trigger (allergen), your immune system fights it by releasing chemicals, such as histamine (hence the term “antihistamine”). Histamine causes symptoms, such as runny nose, itchy nose, sneezing, and itchy and watery eyes.

Allergies, Antibiotics, Drugs

Most people who think they are allergic to penicillin aren’t

About 6% of people in the UK are wrongly labelled on their medical records as being allergic to penicillin. This figure is concerning because being labelled as allergic to this class of highly effective antibiotics is associated with an extra six deaths per 1,000 patients a year after being treated for an infection. If patients received the right antibiotic for their infection, many lives could be saved.
