Side effect details

Allergic Reaction

Humira like any medication may cause allergic reactions with some patients. 6% of those given Humira in clinical study of children with juvenile idiopathic arthritis experienced an allergic reaction within the first 48 weeks of treatment. It is unknown how many of the children receiving the placebo experienced allergic reactions.

In a separate study with children with Crohn’s disease (CD), 5% of the subjects experience mild allergic reactions. Of the children who received the placebo, it’s unknown how many had allergic reactions.

For those taking other medications along with Humira, it is unknown how often allergic reactions occurred.

Symptoms of allergic reactions may include:

  • skin rash
  • itchiness
  • flushing of skin (warmth and reddening of skin)

It’s possible but rare for severe allergic reactions when taking Humira. However, it’s not known how often these have occurred during clinical trials.

  • swelling under the skin, typically the hands & feet, eyelids and lips
  • swelling of throat, mouth or tongue

Long Term Side Effects

Long-term side effects can occur for patients using Humira. These can include the growth of tumors or the development of cancer such as Lymphoma.

Consult your doctor if you have any concerns about the long-term side effects associated with Humira.

Injection Site Reaction

Injection site reactions are common with taking injectable medications including Humira. This was the most common side effect found during clinical studies. It was reported during the study, 20% of subjects taking Humira developed injection site reactions vs 14% of those taking the placebo.

7% of patients stop taking Humira due to injection site reactions. In most cases, the reactions are mild and don’t impact a patients daily life.

Symptoms of injections site reactions may include: swelling, redness, itching, pain or bleeding.

Inform your doctor if you experience injection site reactions during your Humira treatment. Your doctor may provide guidance to help with injection site reactions and ease any discomfort.

Weight Gain

In clinical studies, weight gain wasn’t reported. Weight gain has been reported when used with medications such as TNF (tumor necrosis factor) blockers.

Cancer (such as lymphoma)

Humira includes a black box warning on the packaging as the medication has been known to increase the risk of cancer such as lymphoma. Humira, like other TNF blockers, have been linked to an increased risk of cancer.

Study Results

Adults taking Humira in a clinical study found that people were 3 times more likely to develop lymphoma than those in the US who didn’t take the drug.

Hepatosplenic T-cell lymphoma is a rare form of lymphoma which as been reported in children and young adult men, however in most cases they had ulcerative colitis (UC) or Crohn’s disease (CD).

Aside from lymphoma, nonmelanoma is the second most commonly type of cancer followed by breast cancer, colon cancer, prostate cancer, and lung cancer.

Whether Humira causes cancer is still unknown and there has been conflicting results from studies on whether TNF blockers increase the risk of developing cancer.

Some conditions Humira is used to treat, such as rheumatoid arthritis, are linked with a higher risk of developing lymphoma.

Symptoms of lymphoma

Symptoms of lymphoma may include:

  • weight loss
  • swollen lymph nodes
  • fatigue
  • easily bruise or bleed
  • chills

If you are concerned with the risks associated with taking Humira, speak with your doctor. They can help determine the risk vs benefits of taking this medication or whether they may need to recommend another drug.

Hair Loss

During the clinical trials, hair loss was not reported as a side effect of Humira. However, there have been reports from patients taking Humira after it was released into the market.

Since the reports were released after Humira’s clinical studies, it’s not conclusive whether it plays a role in hair loss.

Consult your doctor if you are concerned about hair loss while taking Humira.

Skin Rash

Skin rashes are one of the most common side effects when taking Humira.

In clinical studies on people with rheumatoid arthritis, 12% reported a rash who were taking Humira compared to 6% who were taking a placebo.

Most cases of skin rashes were mild and eventually went away. Across all studies 0.3% of people stopped taking Humira due to the rashes.

Inform your doctor if you’ve developed a rash while taking Humira as they may provide additional guidance to treat rashes and ease discomfort.

A rash can also be a sign of an allergic reaction. If you develop any symptoms mentioned above associated with allergic reactions, consult your doctor. Seek medical attention immediately if you believe you’re having a severe allergic reaction.


Humira has a black box warning regarding the increased risk of serious infections such as pneumonia or tuberculosis (TB). Since Humira may weaken the immune system it can make patients more susceptible to fight off infections.

Study Results

In clinical studies involving all uses of Humira, people had serious infections caused by fungi, viruses and bacteria. It was found that those who took Humira had higher rates of infection than those who took the placebo. Some people experienced severe infections which required hospitalization and even death.

Before taking Humira, your doctor may test you for tuberculosis. If they find you have an existing TB infection or at risk for TB, they may treat you for TB before and during treatment with Humira. Since you may still develop TB during treatment with Humira, they may test you for TB while taking Humira.

Symptoms of serious infections such as tuberculosis include:

  • fever
  • coughing blood
  • long-lasting cough
  • unexplained weight loss

Notify your doctor immediately if you notice you are experiencing any of these symptoms while taking Humira. Your doctor may choose to pause treatment if they discover a serious infection.

During treatment a doctor should test you for existing infections and check for close signs of TB. If you doctor knows you have TB they may provide you with medication to treat it.

Taking TNF blockers may increase the risk of developing lymphoma or other cancers for adults and children. Cases have been reported in children, teenagers and young adults developing unusual cancers from taking TNF blockers.

A rare type of cancer called heptosplenic T-cell lymphoma has been reported in rare cases that can be fatal.

Humira or TNF blockers may increase chances of developing 2 types of skin cancers called basal cell and squamous cell. These are generally not fatal provided they are treated early. Inform your doctor if you have any open sources or bumps that do not heal.

The Food and Drug Administration tracks side effects on approved drugs.
