An ice pack or cold compress may be all that’s needed for wasp stings, even large local reactions. An over-the-counter painkiller can help relieve discomfort. Calamine lotion, corticosteroid cream or an oral or topical antihistamine may also help ease your symptoms. Particularly painful or widespread swelling may need medical attention and prescription antihistamines or corticosteroids.
Because of the risk of anaphylaxis your healthcare provider is likely to prescribe an epinephrine auto-injector. Epinephrine is another name for adrenaline. The advice is to carry two auto-injectors at all times. This is emergency treatment for you to use in the event of severe reactions. You should also seek immediate medical attention, even if you use your auto-injector, in case you have a delayed secondary reaction.
Wearing a medical alert bracelet will tell people you’re allergic to insect stings so they know how to help you.
