Amoxicillin is an antibiotic drug that belongs to the penicillin family. Amoxicillin used to treat a variety of bacterial infections. It’s the most common antibiotic drug prescribed for kids. Amoxicillin is also among the World Health Organization’s list of essential medicines in the world.

Although amoxicillin is no doubt an important medication, it’s not for everyone. There are individuals who are sensitive or allergic to this drug. Symptoms of an allergic reaction to amoxicillin include rashes, hives and difficulty in breathing.

The symptoms should go away on its own when a person is mildly sensitive to penicillin. There are certain drugs that will ease mild allergic symptoms. But if a person is hopelessly allergic to amoxicillin and the symptoms become progressively worse, rush him to the nearest hospital.  Most types of allergies will stop once the offending agent is removed. However, allergic reaction itself cannot be cured. It can only be treated and controlled.

Symptoms of Amoxicillin Allergy

A person allergic to amoxicillin will exhibit red spots all over the abdomen. It will spread to the face limbs and legs. Gradually, the spots will start itching. This is called amoxicillin rash. There are cases wherein amoxicillin rash develops minutes after ingesting the drug. But there are instances wherein the rash took days to manifest. Depending on the severity of the allergic reaction, the rash will last for three days to a week.

Usually, amoxicillin rash does not require special treatments. Again, unless the individual is deathly allergic to penicillin, the rash will go away on its own. If the rash is accompanied by rapid pulse, labored breathing, and hives, call a doctor immediately. Treatment will include a physical exam for diagnosis and a look at a person’s medical history. If the patient had similar reactions before, let your doctor know about it.  From there, your doctor can suggest different medications as an alternative to amoxicillin.

Treating Amoxicillin Rash

Oatmeal Bath

Oatmeal contains soothing compounds that will bring inflammation and itching down. Just add several spoonfuls of oats in a muslin cloth or a sock. Toss the oats-filled muslin cloth or sock in the bathtub and soak for 15 to 20 minutes.


Over the counter antihistamines like Benadryl or Claritin help alleviate all symptoms of an amoxicillin allergy. You can also apply cortisone cream directly on the rashes to soothe redness and itchiness.


Plain old water helps heal amoxicillin rash. Drinking more than 8 glasses of water will help flush down the antibiotics from your system.

When Symptoms Becomes Dangerous

Severe allergic reaction is common among patients sensitive to penicillin. So always track the progress of the patient. Watch out for the deadlier symptoms of an allergic reaction like anaphylaxis. In severe cases, anaphylaxis will lead to loss of consciousness. In rare cases, anaphylaxis is fatal. If a person cannot breathe after ingesting the drug, he will be given an emergency shot of epinephrine through an IV.

To prevent an allergic reaction to amoxicillin, talk to your doctor. Ask for medications you can take and avoid. If the doctor is unfamiliar with your condition, be sure to let him know about your drug sensitivities. Wear a medical identification necklace or bracelet for good measure.
