The most common side effects of Hadlima are:
- Injection-site reactions: redness, rash, swelling, itching, bruising, or pain where the shot was given
- Upper respiratory infections: cold-like symptoms, sinus infection, sore throat, stuffy/runny nose
- Headache
- Rash
Those are the common side effects listed in Hadlima’s official patient information and FDA-related labeling summaries.
Because Hadlima lowers immune-system activity, you should contact your prescriber promptly if you get signs of infection such as fever, chills, persistent cough, shortness of breath, painful urination, severe fatigue, warm/red/painful skin sores, diarrhea or stomach pain, or if you feel seriously unwell.
Seek urgent care for symptoms of a severe allergic reaction, such as trouble breathing, swelling of the face/lips/throat, or a severe widespread rash.
