Yes, pre-made epinephrine is available in a 1:10,000 concentration, commonly found in EpiPens®, which are used for treating severe allergic reactions or anaphylaxis.
When dealing with emergency systemic anaphylaxis, the initial treatment often includes an injection of epinephrine in a pre-measured dose. This question addresses whether pre-made epinephrine is available in a 1:10,000 concentration and is designed for situations requiring swift action as in the case of a severe allergic reaction. EpiPens® are a prime example of such devices, being auto-injectable syringes that carry epinephrine and can be used through clothing or on bare skin without special training.
The statement that you can use epinephrine pre-made in the 1:10,000 concentration is true. These auto-injectors are essential for individuals with severe allergies as they provide a life-saving dose of medication that counteracts anaphylactic reactions efficiently by dilating blood vessels, increasing heart and respiratory rates, and supporting the body's transport of oxygen during a 'fight-or-flight' situation.
