Typical dosage for Atropen

Prefilled Atropen autoinjectors are available in several dosage strengths: 0.25 mg, 0.5 mg, 1 mg, and 2 mg. Your dosage strength is based on your age and body weight. Your dose can be given up to three times depending on how severe your symptoms are.

In general:

  • Mild symptoms: If there are at least two mild symptoms, give 1 Atropen injection into the muscle of the outer thigh. If there are any severe symptoms after the first injection, give 2 more Atropen injections into the muscle of the outer thigh quickly, one right after the other. Use a new pen for each injection.
  • Severe symptoms: If unconscious (passed out) or if there are any severe symptoms, give 3 Atropen injections into the muscle of the outer thigh quickly, one right after the other. Use a new pen for each injection.
