What If I Take an Overdose?
An Avonex overdose is unlikely, for various reasons. It is not known exactly what to expect from an overdose on this medication.
Avonex (both the vials and prefilled syringes) must be stored in the refrigerator. Make sure to take your Avonex dose out of the refrigerator for about 30 minutes before you inject it (to allow it to come to room temperature). If absolutely necessary, it can be stored outside the refrigerator, up to 77 degrees F for a maximum of 30 days (for the unmixed vials) or for 7 days (for the prefilled syringes). Once you mix a vial of Avonex, it should be used as soon as possible within six hours (stored under refrigeration).
Do not freeze Avonex. If you use cold packs to transport Avonex, be sure that the medication does not freeze.
In all cases, it should be protected against high temperatures or light exposure. Keep Avonex and all other medications out of the reach of children.
What If I Miss a Dose of Avonex?
If you forget to take a dose, simply take the missed dose as soon as you remember and continue with your regular Avonex schedule the following week. However, do not take the drug on two consecutive days.
Avonex comes in one of the following strengths:
- Avonex 30 mcg lyophilized powder vial
- Avonex 30 mg prefilled syringes.
Both types of Avonex come with alcohol wipes, gauze pads, a bandage, and a 23 gauge, 1.25 inch needle. The lyophilized powder vial also comes with everything you need to mix the injection.
