Why it’s used

How it works

Humira belongs to a class of drugs called tumor necrosis factor (TNF) blockers. A class of drugs is a group of medications that work in a similar way. These drugs are often used to treat similar conditions.

TNF is a substance in your body that causes inflammation and makes your immune system react. If you have a disease that causes your body to make too much TNF, Humira can help block it.

Humira doesn’t cause drowsiness, but it can cause other side effects.

Warnings for people with certain health conditions

For people at risk of, or with, tuberculosis: This drug affects your immune system and may cause a new TB infection or reactivate an older existing TB infection. Your doctor may check you for TB before you start Humira. If your doctor feels that you’re at risk of TB or if you have an existing TB infection, you may be treated with drugs for TB before and during treatment with Humira.

Even if your TB test is negative, your doctor may carefully monitor you for TB infection. This is because you may still develop a TB infection while you’re taking this drug, even if you had a negative TB test.

Warnings for other groups

For pregnant women: Humira crosses into the placenta during pregnancy. It does so in increasing amounts as pregnancy progresses, with the largest amount of drug being transferred into the placenta during the third trimester.

A pregnancy registry called the Organization of Teratology Information Specialists (OTIS)/MotherToBaby HUMIRA Pregnancy Registry studied Humira.

The registry studied pregnant women with rheumatoid arthritis or Crohn’s disease who took this drug during the first trimester. It compared the women to mothers with these diseases who did not take adalimumab.

Results from the registry showed an increased rate of birth defects in children born to mothers who took the drug. However, it’s not clear if there’s an association between adalimumab and major birth defects.

Talk to your doctor if you’re pregnant or planning to become pregnant. This drug should only be used in pregnancy if clearly needed.

For women who are breastfeeding: Humira can pass through breast milk in small amounts. However, studies of babies who were exposed to Humira through breast milk showed no side effects.

Talk to your doctor if you breastfeed your child. You may need to decide whether to stop breastfeeding or stop taking this medication.

For seniors: If you’re over the age of 65 years, you may be at higher risk for a serious infection or certain types of cancers while taking this drug.

For children: The safety and effectiveness of this drug haven’t been established in:

  • children younger than 18 years for conditions other than juvenile idiopathic arthritis and Crohn’s disease
  • children younger than 2 years for the treatment of juvenile idiopathic arthritis
  • children younger than 6 years for the treatment of Crohn’s disease

Humira is used for long-term treatment. It comes with serious risks if you don’t take it as prescribed.

If you stop taking the drug or don’t take it at all: Your inflammation won’t be controlled and may get worse.

If you miss doses or don’t take the drug on schedule: Your medication may not work as well or may stop working completely. For this drug to work well, a certain amount needs to be in your body at all times.

If you take too much: You could have dangerous levels of the drug in your body.

If you think you’ve taken too much of this drug, call your doctor or seek guidance from the American Association of Poison Control Centers at 800-222-1222 or through their online tool. But if your symptoms are severe, call 911 or go to the nearest emergency room right away.

What to do if you miss a dose: If you miss a dose, take it as soon as possible. However, if it’s almost time for your next dose, take the next dose only. Don’t take double or extra doses.

How to tell if the drug is working: You may be able to tell if this drug is working if you have less inflammation from your condition.

  • For psoriatic arthritis, rheumatoid arthritis, and ankylosing spondylitis, you may have less joint pain and be able to move better.
  • For ulcerative colitis and Crohn’s disease, you may have less diarrhea, bloody stools, and stomach pain.
  • For plaque psoriasis, your skin may look better.
  • For hidradenitis suppurativa, you may have less pain and fewer lumps under your skin.
  • For uveitis, your eye symptoms should improve.

Keep these considerations in mind if your doctor prescribes Humira for you.
