Warnings

The usual dose of Twinject (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 Twinject (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 Twinject (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.

stop taking one of the medications,

change how you are taking one or both of the medications, or
leave everything as is.

An interaction between two medications does not always mean that you must stop taking one of them. Speak to your doctor about how any drug interactions are being managed or should be managed.

Medications other than those listed above may interact with Twinject (Epinephrine). Tell your doctor or prescriber about all prescription, over-the-counter (non-prescription), and herbal medications you are taking. Also tell them about any supplements you take. Since caffeine, alcohol, the Nicotine from cigarettes, or street drugs can affect the action of many medications, you should let your prescriber know if you use them.

Before you begin using a medication, be sure to inform your doctor of any medical conditions or Allergies you may have, any medications you are taking, whether you are pregnant or breast-feeding, and any other significant facts about your health. These factors may affect how you should use Twinject (Epinephrine).

Heart disease: Twinject (Epinephrine) has many effects throughout the body. It narrows the blood vessels, which in turn can increase blood pressure, heart rate and possibly cause irregular heartbeat. If you have heart disease, including high blood pressure, abnormal heartbeat or are taking medications that increase the risk of an irregular heartbeat (e.g., Digoxin, Amiodarone, Sotalol, procainamide), or have an overactive Thyroid, these conditions can be made worse for a short period of time, by using Twinject (Epinephrine).

Be sure to tell any emergency professionals if you have any of these conditions and that you have used Twinject (Epinephrine).
