The usual dose of epinephrine is based on your body weight, your risk of experiencing a serious allergic reaction, and your ability to tolerate the medication. The usual dose for children and adults who weigh 30 kg or more is 0.3 mg. For adults and children who weigh 15 kg to 30 kg, the dose is 0.15 mg. For children who weigh less than 15 mg, other forms of injectable epinephrine may be prescribed.
The medication is injected into the thigh with use of an autoinjector, which is a device that resembles a pen. To use the autoinjector, remove the caps on each end. Then, place the red tip of the pen against the thigh and press hard, holding it there to let the plunger activate (the needle will be pushed into the thigh muscle to inject a dose of epinephrine). The needle can go through clothes. Hold the pen against the thigh as you count to 10. After counting to 10, remove the device from your thigh. Seek medical attention immediately.
If the symptoms have not improved within about 10 minutes, administer a second dose. Prepare the second dose by unscrewing the rounded tip, pulling the syringe from the barrel and sliding the yellow collar off the plunger. Inject the dose by placing the needle into the thigh and pushing the plunger. It is important to know how to use the autoinjector. If you are not sure, ask your doctor, nurse, or pharmacist for a demonstration.
Many things can affect the dose of a medication that a person needs, such as body weight, other medical conditions, and other medications. If your doctor has recommended a dose different from the ones listed here, do not change the way that you are using the medication without consulting your doctor.
Store this medication at room temperature, protect it from light, and keep it out of the reach of children. The pen should be stored in its original tube. Do not use it if the solution is darker than light yellow or has particles in it.
Do not dispose of medications in wastewater (e.g. down the sink or in the toilet) or in household garbage. Ask your pharmacist how to dispose of medications that are no longer needed or have expired.
