Check your skin regularly for unusual growths or discolouration and report any changes to your doctor as soon as possible. Talk to your doctor about any concerns you may have.

Systemic lupus erythematosus: This medication can worsen or activate the symptoms of lupus. If you experience swollen and painful joints, fever, fatigue, or rash on the nose and cheeks while taking this medication, contact your doctor.
