Medications That May Provoke Asthma

Aspirin And Nonsteroidal Anti-Inflammatory Drugs

Some people with asthma are sensitive to aspirin and most other nonsteroidal anti-inflammatory drugs (NSAIDs), which are commonly used as pain medications. These drugs can result in severe, hard-to-control attacks for people who are sensitive to them.

A reaction to aspirin and related drugs is not a true allergy. The key chemical in allergic reactions is histamine. In people with aspirin and NSAID sensitivity, a chemical called leukotriene causes the problem.

If you have a lot of leukotrienes in your system, they can trigger asthma by causing inflammation in the airways and making the airways create mucus. They also can cause eye tearing and sinus symptoms, such as a runny or stuffy nose. Occasionally they cause swelling of the tongue and tissues in and around the mouth and throat. This swelling, called angioedema, is a dangerous problem because it may block breathing. Sensitivity to aspirin and related drugs is one reason that people can form nasal polyps (bulges of swollen tissue that grow from the lining of the nasal passages).

It is likely that everyone who uses aspirin and NSAIDs forms a few extra leukotriene molecules. The people who make the most leukotrienes are the people who are likely to have aspirin-induced asthma and other symptoms from aspirin and most other NSAID drugs. Typical timing is for this sensitivity to begin in adults who are between 20 and 40 years old.

In addition to aspirin, over-the-counter NSAIDs include ibuprofen (common brand names are Advil and Motrin) and naproxen (Aleve). Examples of prescription NSAIDs include sulindac (Clinoril), diclofenac (Voltaren), piroxicam (Feldene), ketoprofen (Orudis), diflunisal (Dolobid), nabumetone (Relafen), etodolac (Lodine), oxaprozin (Daypro) and indomethacin (Indocin).

The type of NSAID that is called a COX-2 inhibitor, celecoxib (Celebrex), has been tested in aspirin-sensitive people. It is less likely to trigger an increase in leukotrienes for most individuals. If you absolutely need to take an anti-inflammatory pain medicine, you and your doctor may consider a test dose while you are directly observed in the office.

To identify products containing aspirin or NSAIDs, carefully review the active-ingredient list or ask your pharmacist. Products that contain aspirin or NSAIDs that could trigger asthma attacks include:

  • Some cold tablets
  • Medications for menstrual symptoms
  • Prescription drugs containing aspirin, such as the painkiller Percodan and the headache remedy Fiorinal.

An acetaminophen product such as Tylenol, Panadol or Aspirin-Free Anacin is usually recommended for aspirin-sensitive asthmatics, as acetaminophen much more rarely causes asthma symptoms.

Even though aspirin is a salicylate, other salicylate medicines (such as Disalcid) and salicylates in food do not appear to aggravate asthma in aspirin-sensitive patients. If you are aspirin sensitive, you must always warn your health care provider before receiving any pain medications.

If you have asthma or eye and sinus symptoms that are triggered by aspirin or NSAIDs, then your asthma may improve if you are treated with a drug that specifically blocks the effect of leukotrienes. Medicines known as leukotriene modifiers include zileuton (Zyflo), montelukast (Singulair) and zafirlukast (Accolate).

Drugs called beta-blockers may cause or worsen asthma in some people by causing the airway muscles to tighten. These drugs are used to treat migraine headaches, glaucoma, irregular heart rhythm, high blood pressure, tremors and other conditions. They are commonly prescribed to people who have had a heart attack.

There are general beta blockers, such as propranolol (Inderal) and nadolol (Corgard) and heart-selective beta blockers, such as atenolol (Tenormin) and metoprolol (Lopressor). If you need a beta-blocker, you doctor will likely choose one that is heart-selective or an alternative drug from a different class.
