Medical condition warnings
If a person who has hepatitis B takes RA drugs, they may be at risk of fatigue or yellowing skin.
Many RA drugs could potentially make a hepatitis B virus infection active in those who have the virus.
Individuals with hepatitis B taking such drugs may experience:
- yellowing skin
- pain on the right side of the stomach, and low appetite when taking medication
An active infection can have serious consequences, including liver failure and death.
Before a person receives RA drugs such as Enbrel or Humira, a doctor will order a blood test to ensure there is no hepatitis B infection.
Enbrel and Humira are very similar medications that people with RA use to relieve their symptoms.
The slight difference between the drugs may make one or the other a better choice. Whether or not either drug is appropriate depends on each case.
People should talk to a doctor to learn more about Enbrel and Humira and discuss what the best option may be.
