Common Side Effects
Injection Site Reactions
Redness, swelling, or mild pain at the injection site are the most common side effects of subcutaneous biologics. These typically resolve within a few days.
Upper Respiratory Infections
Biologics that modify immune function may increase susceptibility to upper respiratory infections. Contact your provider if symptoms are severe or prolonged.
Fatigue
Some patients report fatigue, particularly when beginning biologic therapy. This often improves as treatment continues.
Nausea
Mild nausea may occur, particularly with oral biologics like JAK inhibitors. Taking medication with food may help.
