Do not try to inject Humira yourself until you have been shown the right way to give the injections. If your doctor decides that you or a caregiver may be able to give your injections of Humira at home, you should receive training on the right way to prepare and inject Humira.

Do not miss any doses of Humira unless your doctor says it is okay. If you forget to take Humira, inject a dose as soon as you remember. Then, take your next dose at your regular scheduled time. This will put you back on schedule.

In case you are not sure when to inject Humira, call your doctor or pharmacist.

If you take more Humira than you were told to take, call your doctor.
