Each inhalation contains the equivalent of 0.16 milligrams epinephrine delivered at the mouthpiece. Inhalation dosage for adults and children 4 years of age and older: start with one inhalation, then wait at least one minute. If not relieved, use Medihaler-Epi once more. Do not use again for at least three hours. The use of this product by children should be supervised by an adult. Children under 4 years of age: consult a physician.

Medihaler-Epi delivers the same dose every time. It does not depend on the strength with which the canister is pressed against the oral adapter or on the time the canister is held down. The canister must be released before it can be depressed again for another dose.

Medihaler-Epi is designed to deliver a sufficient dose for most people in one or occasionally two inhalations. It is not necessary to use several applications in rapid succession. Use only when you actually need relief. Do no get into the habit of using Medihaler-Epi indiscriminately.

Before each use, remove dust cap and inspect oral adapter for foreign objects. Shake MADIHALER-EPI well. To get the medication deep into the lungs, follow these three simple steps which can be completed within five seconds:

  1. Breath out fully and place mouthpiece well into the mouth, aimed at the back of the throat.
  2. As you begin to breathe in deeply, press the canister firmly down into the adapter with the index finger, and continue to inhale. This releases one dose.
  3. Release pressure on canister and remove unit from the mouth. Hold the breath as long as possible, then breathe out slowly.

Replace dust cap after each use.

Medihaler-Epi is packaged in a shatterproof aluminum canister fitted with a specially designed valve. It can be used only with the Medihaler-Epi oral adapter, a non-breakable inhaler device.
