The most common signs are rash and breathing problems.
If the person cannot swallow, or is having trouble breathing, give epinephrine right away. You can give another dose in 5 to 15 minutes if necessary.
Epinephrine comes in different strengths and different amounts may be needed to give the same dose. Figure out the correct amount and have it ready in a medicine kit before emergencies happen. Or stock a pre‑loaded injection, called an EpiPen or known by other brand names.
Inject epinephrine in the thigh muscle, here:
For breathing problems you can also give salbutamol. It is also a good idea to give an antihistamine.
In most cases, if you ever have an allergic reaction to a medicine, food, bee sting, or something else, you should avoid it forever after. The second time you are exposed you can expect an even worse reaction.
