Avsola (infliximab-axxq)

What are the side effects of Avsola?



Serious Infections

Patients treated with infliximab products are at increased risk for developing serious infections that may lead to hospitalization or death. Most patients who developed these infections were taking concomitant immunosuppressants such as methotrexate or corticosteroids.

Avsola should be discontinued if a patient develops a serious infection or sepsis.

Reported infections include:

  • Active tuberculosis, including reactivation of latent tuberculosis. Patients with tuberculosis have frequently presented with disseminated or extrapulmonary disease. Patients should be tested for latent tuberculosis before Avsola use and during therapy. Treatment for latent infection should be initiated prior to Avsola use.
  • Invasive fungal infections, including histoplasmosis, coccidioidomycosis, candidiasis, aspergillosis, blastomycosis, and pneumocystosis. Patients with histoplasmosis or other invasive fungal infections may present with disseminated, rather than localized, disease. Antigen and antibody testing for histoplasmosis may be negative in some patients with active infection. Empiric anti-fungal therapy should be considered in patients at risk for invasive fungal infections who develop severe systemic illness.
  • Bacterial, viral and other infections due to opportunistic pathogens, including Legionella and Listeria.

The risks and benefits of treatment with Avsola should be carefully considered prior to initiating therapy in patients with chronic or recurrent infection.

Patients should be closely monitored for the development of signs and symptoms of infection during and after treatment with Avsola, including the possible development of tuberculosis in patients who tested negative for latent tuberculosis infection prior to initiating therapy.


Lymphoma and other malignancies, some fatal, have been reported in children and adolescent patients treated with TNF-blockers, including infliximab products.

Postmarketing cases of hepatosplenic T-cell lymphoma (HSTCL), a rare type of T-cell lymphoma, have been reported in patients treated with TNF-blockers including infliximab products. These cases have had a very aggressive disease course and have been fatal. Almost all patients had received treatment with azathioprine or 6-mercaptopurine concomitantly with a TNF-blocker at or prior to diagnosis. The majority of reported cases have occurred in patients with Crohn’s disease or ulcerative colitis and most were in adolescent and young adult males.

Avsola can cause serious side effects, including:

Serious Infections

  • Some patients, especially those 65 years and older have had serious infections while receiving infliximab products, such as Avsola. These serious infections include TB and infections caused by viruses, fungi, or bacteria that have spread throughout the body. Some patients die from these infections. If you get an infection while receiving treatment with Avsola your doctor will treat your infection and may need to stop your Avsola treatment.
  • Tell your doctor right away if you have any of the following signs of an infection while receiving or after receiving Avsola:
  • Your doctor will examine you for TB and perform a test to see if you have TB. If your doctor feels that you are atrisk for TB, you may be treated with medicine for TB before you begin treatment with Avsola and during treatment with Avsola.
  • Even if your TB test is negative, your doctor should carefully monitor you for TB infections while you are receiving Avsola. Patients who had a negative TB skin test before receiving infliximab products have developed active TB.
  • If you are a chronic carrier of the hepatitis B virus, the virus can become active while you are being treated with Avsola. In some cases, patients have died as a result of hepatitis B virus being reactivated. Your doctor should do a blood test for hepatitis B virus before you start treatment with Avsola and occasionally while you are being treated. Tell your doctor if you have any of the following symptoms:

Heart Failure

If you have a heart problem called congestive heart failure, your doctor should check you closely while you are receiving Avsola. Your congestive heart failure may get worse while you are receiving Avsola. Be sure to tell your doctor of any new or worse symptoms including:

Treatment with Avsola may need to be stopped if you get new or worse congestive heart failure.

Other Heart Problems

Some patients have experienced a heart attack (some of which led to death), low blood flow to the heart, or abnormal heart rhythm within 24 hours of beginning their infusion of infliximab products. Symptoms may include

  • chest discomfort or pain,
  • arm pain,
  • stomach pain,
  • shortness of breath,
  • anxiety,
  • lightheadedness,

  • jaundice (skin and eyes turning yellow)
  • dark brown-colored urine
  • pain on the right side of your stomach area (right-sided abdominal pain)
  • fever
  • extreme tiredness (severe fatigue)

Blood Problems

  • look very pale
  • bruise or bleed very easily

Nervous System Disorders

Some patients receiving infliximab products have developed problems with their nervous system. Tell your doctor if you have:

  • changes in your vision

Some patients have experienced a stroke within approximately 24 hours of their infusion with infliximab products. Tell your doctor right away if you have symptoms of a stroke which may include: numbness or weakness of the face, arm or leg, especially on one side of the body; sudden confusion, trouble speaking or understanding; sudden trouble seeing in one or both eyes, sudden trouble walking, dizziness, loss of balance or coordination or a sudden, severe headache.

Allergic Reactions

Some patients have had allergic reactions to infliximab products. Some of these reactions were severe. These reactions can happen while you are getting your Avsola treatment or shortly afterward. Your doctor may need to stop or pause your treatment with Avsola and may give you medicines to treat the allergic reaction. Signs of an allergic reaction can include:

Some patients treated with infliximab products have had delayed allergic reactions. The delayed reactions occurred 3 to 12 days after receiving treatment with infliximab products. Tell your doctor right away if you have any of these signs of delayed allergic reaction to Avsola:

Lupus-like Syndrome

Some patients have developed symptoms that are like the symptoms of Lupus. If you develop any of the following symptoms, your doctor may decide to stop your treatment with Avsola.

  • chest discomfort or pain that does not go away
  • joint pain
  • shortness of breath
  • rash on the cheeks or arms that gets worse in the sun


Some people receiving infliximab products had new psoriasis or worsening of psoriasis they already had. Tell your doctor if you develop red scaly patches or raised bumps on the skin that are filled with pus. Your doctor may decide to stop your treatment with Avsola.

The most common side effects of infliximab products include:

Infusion reactions can happen up to 2 hours after your infusion of Avsola.

Symptoms of infusion reactions may include:

Children with Crohn’s disease showed some differences in side effects compared with adults with Crohn’s disease. The side effects that happened more in children were:

  • anemia (low red blood cells),
  • leukopenia (low white blood cells),
  • flushing (redness or blushing),
  • viral infections,
  • neutropenia (low neutrophils, the white blood cells that fight infection),
  • bone fracture,
  • bacterial infection and
  • allergic reactions of the breathing tract.

Among patients who received infliximab for ulcerative colitis in clinical studies, more children had infections as compared with adults.

Tell your doctor about any side effect that bothers you or does not go away. These are not all of the side effects with Avsola.

Ask your doctor or pharmacist for more information. Call your doctor for medical advice about side effects. You may report side effects to FDA at 1-800-FDA-1088.
