Allergy shots, also known as allergen immunotherapy, are a long-term treatment that aims to desensitize the body to specific allergens. While they can be an effective way to manage allergies, they can also have side effects. Understanding these side effects is crucial to making an informed decision about whether allergy shots are right for you. As someone with over a decade of experience in the field of allergy and immunology, I will walk you through the common and rare side effects of allergy shots, as well as what you can expect during and after treatment.
Common Allergy Shot Side Effects
Most people who receive allergy shots experience some side effects, but they are usually mild and temporary. The most common side effects include:
- Redness, swelling, or itching at the injection site
- Runny nose or nasal congestion
- Sneezing or coughing
- Fatigue or dizziness
These side effects typically occur within a few hours of the injection and resolve on their own within a day or two. In some cases, people may experience more severe side effects, such as:
Moderate Side Effects
Moderate side effects are less common but can be more concerning. They may include:
- Hives or itchy skin
- Swelling of the face, lips, or tongue
- Stomach cramps or diarrhea
- Joint pain or muscle aches
If you experience any of these side effects, it's essential to contact your doctor or allergist immediately. They can provide guidance on how to manage the symptoms and may adjust your treatment plan accordingly.

| Mild side effects | 80-90% |
| Moderate side effects | 5-10% |
| Severe side effects | 1-5% |
