Uses

This medication is used in emergencies to treat very serious allergic reactions to insect stings/bites, foods, drugs, or other substances. Epinephrine works quickly to improve breathing, stimulate the heart, raise a dropping blood pressure, reverse hives, and reduce swelling of the face, lips, and throat.

How To Use

The solution in this product should be clear. From time to time, check this product visually for particles or discoloration. If it has turned cloudy or pink/brown in color, do not use the product. Discard and replace it.

Different brands of this medication have different directions for preparing and using this medication. Learn ahead of time how to properly inject this medication so you will be ready if you need to use it. Also, make sure a family member, caregiver, or other responsible person knows where you keep this medication and how to use it in case you cannot inject the medication yourself. The dosage is based on your medical condition, weight, and response to treatment.

Inject this medication into the thigh as directed by your doctor and the manufacturer. This medication can be injected through clothing if needed. This medication acts quickly but does not last long. After injecting epinephrine, get medical help right away. Tell the health care professional that you have given yourself an injection of epinephrine. You may need another dose of epinephrine if your symptoms do not get better, or if they return after one dose.

Avoid injecting this medication into the hands, feet, buttocks, or areas of your body other than the thigh. If this accidentally happens, get medical help right away. For infants and young children, be sure to hold their leg firmly in place before and during the injection to prevent injury. Discard the injector properly after use.

Fast/pounding heartbeat, nervousness, sweating, nausea, vomiting, trouble breathing, headache, dizziness, anxiety, shakiness, or pale skin may occur. If any of these effects last or get worse, tell your doctor or pharmacist promptly.
