When choosing a new treatment, it's important to understand both the benefits and the risks. Here is some of the most important information you need to know about safety and side effects of Tysabri®.
What side effects may occur?
Some of the possible side effects of Tysabri include dizziness, nausea, headache, joint pain, tiredness, shivering, sore throat, infections, and runny or stuffy nose.
Occasionally, people may have an allergic reaction to Tysabri. If you have symptoms of a serious allergic reaction, such as hives, swelling of the face, lips or throat, or difficulty breathing, seek immediate medical attention.
Tysabri can increase the risk of a rare but serious neurological condition called PML (progressive multifocal leukoencephalopathy), which can lead to severe disability or death. PML symptoms are similar to the symptoms of MS, so check with your doctor if your MS seems to be getting worse or if you have new MS symptoms.
Who should not take Tysabri?
Tysabri should not be used during pregnancy unless you and your doctor determine that the benefits outweigh the risks. It is not known whether Tysabri passes into breast milk, so women using Tysabri should avoid breast-feeding.
Tysabri has not been studied in children under 18 years of age.
People with serious immune system problems (such as HIV or leukemia), those who have or have had PML, and those who are allergic to any ingredient of the medication should not take Tysabri.
The safety and effectiveness of using Tysabri for more than 2 years are not known.
What else do I need to know?
Speak to your doctor if:
- your MS seems to be getting worse
- you develop new MS symptoms
- you have any other symptoms that worry you
- you become pregnant
- you start any new medications (especially medications that affect the immune system, such as cancer or transplant medications)
