Allergic erythema multiforme reaction to amoxicillin in children and


Babies are delicate creatures who often experience various health issues. One common concern is an allergic reaction to amoxicillin, an antibiotic commonly prescribed to treat bacterial infections in infants.

Understanding Amoxicillin Allergy

Amoxicillin is a widely used antibiotic that belongs to the penicillin family. While it is generally safe and effective, some babies may develop an allergic reaction to this medication. An allergic reaction occurs when the body’s immune system mistakenly identifies amoxicillin as harmful and initiates an immune response.

Causes of Amoxicillin Allergy in Babies

The exact cause of amoxicillin allergy in babies is still not fully understood. However, there are several factors that may contribute to the development of this allergic reaction:

  • A family history of drug allergies
  • Previous allergic reactions to other medications
  • Exposure to amoxicillin at an early age
  • A weakened immune system

Symptoms of Amoxicillin Allergy

The symptoms of an allergic reaction to amoxicillin in babies can vary from mild to severe. It is important to be aware of these symptoms to seek immediate medical attention:

Mild Symptoms

• Rash or hives on the skin
• Itchy or watery eyes
• Runny or stuffy nose
• Sneezing or coughing
• Mild gastrointestinal discomfort

Severe Symptoms

• Swelling of the face, lips, tongue, or throat
• Difficulty breathing or wheezing
• Rapid heartbeat
• Dizziness or lightheadedness
• Nausea and vomiting
• Diarrhea

Diagnosing Amoxicillin Allergy

If you suspect that your baby is experiencing an allergic reaction to amoxicillin, it is crucial to consult a healthcare professional for an accurate diagnosis. The doctor will review the symptoms and may perform the following tests:

Skin Prick Test

A small amount of amoxicillin extract is placed on the baby’s skin, and a tiny needle is used to prick the skin. If a red, itchy bump appears within 15-20 minutes, it indicates a positive reaction to amoxicillin.

Blood Test

A blood sample is taken to measure the levels of antibodies produced in response to amoxicillin. Elevated levels of specific antibodies can indicate an allergic reaction.

Treatment for Amoxicillin Allergy

If your baby is diagnosed with an allergic reaction to amoxicillin, the doctor will recommend the following treatments:

Immediate Discontinuation of Amoxicillin

The first step in treatment is to stop giving your baby amoxicillin. This will prevent the allergic reaction from worsening and allow the body to recover.


Antihistamines can help alleviate mild symptoms such as rashes, itching, and sneezing. However, they should only be administered under the guidance of a healthcare professional.


In cases of severe allergic reactions, where there is a risk of anaphylaxis, the doctor may prescribe an EpiPen. This device contains epinephrine, a medication that can quickly reverse the symptoms of an allergic reaction and prevent further complications.

Prevention Tips

While it may not always be possible to prevent amoxicillin allergy in babies, there are some measures you can take to minimize the risk:

  • Inform healthcare providers about any previous allergic reactions to medications.
  • Monitor your baby closely for any signs of an allergic reaction after starting amoxicillin.
  • If your baby has a known allergy to penicillin, inform the doctor to avoid prescribing amoxicillin.
  • Follow the prescribed dosage and duration of amoxicillin as recommended by the healthcare professional.


Amoxicillin allergy can be a concerning issue for babies, but with prompt diagnosis and appropriate treatment, most cases can be managed effectively. It is essential for parents and caregivers to be vigilant and seek medical attention if they suspect their baby is experiencing an allergic reaction to amoxicillin. By following prevention tips and working closely with healthcare professionals, you can ensure the safety and well-being of your little one.
