Table of Contents ▾

Many of us use painkillers for headaches, body aches, or toothaches, right? But for some people, when they take these painkillers , especially aspirin, they suddenly start to hurt their bodies, have difficulty breathing, and their faces start to swell. We often think that this is an 'allergy', that is, an allergy. But you know, this is not always a true allergy. It can be a little different, a 'sensitivity'. Let's talk about this simply and clearly today.

What exactly is 'aspirin sensitivity'?

Simply put, some people are actually allergic to aspirin. That is, their immune system recognizes aspirin as an enemy and reacts against it.

But, another group of people have what doctors call a 'non-allergic sensitivity'. That means they get symptoms when they take aspirin, sometimes they can be dangerous. But it's not an allergy that involves the immune system. It's caused by a different chemical process in the body.

This problem is not unique to aspirin. A similar group of painkillers can also cause this type of reaction. We call this group ' Nonsteroidal Anti-inflammatory Drugs' (NSAIDs) . These are the drugs we use most often. Here are a few examples:

The important thing is that if you are allergic to aspirin, you are more likely to be allergic to the other NSAIDs mentioned, so it is important to be aware of this.

What are the symptoms of this sensitivity?

Watch for one or more of these symptoms after taking aspirin or another NSAID. These symptoms usually appear within a few hours of taking the medication.

SymptomWhat can happen?
Skin problems Itchy hives and red spots (rash) all over the body.
Face and eyes Red eyes, flushing, swelling of the lips, tongue, or face.
Respiratory system problems Nasal congestion, runny nose , headache, difficulty breathing, wheezing.
Digestive system Nausea, stomach cramps, or vomiting.

What is the special condition called Sumter's Triad?

This is a specific and somewhat complex condition related to aspirin sensitivity. It is also called 'Aspirin-Exacerbated Respiratory Disease' (AERD). A person with this condition has three main problems at once.

1. Reaction to aspirin and NSAIDs: This means that the symptoms mentioned above appear when taking these medications.

2. Asthma : Asthma is a condition that usually lasts for a long time. Taking this medicine can cause a sudden worsening of the asthma condition.

3. Nasal Polyps: Small growths that form in the nasal passages. These often cause problems like nasal congestion and loss of smell.

Imagine you've had asthma for a long time, and you often have a stuffy nose and a reduced sense of smell. If you suddenly find yourself short of breath and your asthma gets worse when you take a painkiller like aspirin or ibuprofen, you may have Samter's Triad.

Experts are still not sure why all three of these problems occur together. It has been found that between 3% and 5% of asthmatics have aspirin sensitivity. The condition is more common in women. Symptoms usually begin in their 30s. For some people, drinking alcohol can worsen these symptoms and cause a severe asthma attack that requires emergency treatment .

How to manage this problem?

If you suspect you have this problem, don't panic. There are several things you can do to control it and stay safe.

What to do in an emergency

If you suddenly develop severe symptoms such as swelling of your lips or throat, difficulty breathing, or wheezing, it can be life-threatening. Therefore, go to the nearest hospital's Emergency Department (ETU) without delay.

Avoid taking these medications completely.

If your doctor confirms that you have an aspirin sensitivity, you should avoid taking aspirin and other NSAIDs (such as ibuprofen and naproxen) completely. If you need medicine for pain or fever, acetaminophen , also known as paracetamol, is generally safe. However, it is best to consult your doctor before taking any medication.

Be careful when choosing medicine.

Did you know that some over-the-counter medicines and syrups for colds, flu, coughs, and stomach upsets may contain aspirin or other NSAIDs? So, before you buy a medicine from a pharmacy, read the label to see what it contains. Some cosmetics, soaps, and shampoos may even contain small amounts of these. If you have any doubts, ask your doctor to confirm.

Control symptoms

If you have problems like asthma and nasal congestion, take the medications your doctor prescribes to help control your symptoms. Your doctor may also prescribe steroids for a short period of time.

Special treatments

A special treatment for this is called 'desensitization' . This involves starting you on a very small dose of aspirin under the close supervision of a doctor and gradually increasing the dose. If this is successful, you may be able to take aspirin daily without any problems. This method can even help relieve asthma and sinus problems.

Nasal Polyps Removal

If you have a lot of discomfort due to nasal polyps, your doctor may suggest surgical removal. But remember, sometimes these can grow back.
