Self-Care at Home
For hives or localized skin reactions, perform the following:
- Take cool showers or apply cool compresses.
- Wear light clothing that doesn't irritate your
- Take it easy. Keep your activity level low.
- To relieve the itching, apply calamine lotion or take nonprescription antihistamines, such as diphenhydramine (Benadryl) or chlorpheniramine maleate (Chlor-Trimeton).
For more severe reactions, self-treatment is not recommended. Call your
health-care provider or 911, depending on the severity of your symptoms. If you have symptoms of anaphylaxis, here's what you can do while waiting for the ambulance:
- Try to stay calm.
- If you can identify the cause of the reaction,
prevent further exposure.
- Take an antihistamine (one to two tablets or capsules
of diphenhydramine [Benadryl]) if you can swallow without difficulty.
- If you are wheezing or having difficulty breathing, use an inhaled bronchodilator such as albuterol (Proventil) or epinephrine (Primatene Mist) if one is available. These inhaled medications dilate the airway.
- If you are feeling light-headed or faint, lie down and raise your legs higher than your head to help blood flow to your brain.
- If you have been given anepinephrine kit, inject yourself as you have been instructed. The kit provides a premeasured dose of epinephrine, a prescription drug
that rapidly reverses the most serious symptoms.
- Bystanders should administer CPR to a person who becomes unconscious and stops breathing or does not have a pulse.
- If at all possible, you or your companion should be prepared to tell medical personnel what medications you take and any known allergies.
