Find answers to some frequently asked questions about Pulmicort and possible interactions.

Pulmicort is safe to use as a long-term treatment. The drug can be used long term to help manage and prevent asthma symptoms in adults and some children. Your doctor will tell you how long you can expect to use Pulmicort.

In certain situations, you may be able to use Pulmicort with nasal sprays or other inhalers.

For example, if your doctor tells you it’s safe, you may use Pulmicort with a nasal spray. An example of a nasal spray is Nasonex (mometasone). In addition, your doctor may prescribe Pulmicort along with certain other inhalers, including Atrovent (ipratropium).

But your doctor isn’t likely to prescribe Pulmicort with Symbicort (budesonide/formoterol). This is because Pulmicort and Symbicort both contain the active drug budesonide. Your doctor will likely avoid prescribing two forms of the same active drug.

In addition to budesonide, Symbicort contains the active drug formoterol. If your doctor would like to prescribe budesonide with formoterol, they’re likely to prescribe Symbicort on its own. They’ll do this instead of prescribing Pulmicort along with Symbicort.

If you have other questions about using nasal sprays or other inhalers with Pulmicort, talk with your doctor.

Yes, it’s safe to combine Pulmicort with certain over-the-counter (OTC) pain relievers.

For example, there isn’t a known interaction between Pulmicort and acetaminophen (Tylenol). It should be safe to use these drugs together.

But other OTC pain relievers may interact with Pulmicort. This includes aspirin and nonsteroidal anti-inflammatory drugs (NSAIDs). Ibuprofen (Advil) and naproxen (Aleve) are examples of NSAIDs.

Long-term use of Pulmicort with aspirin or NSAIDs could increase your risk of a stomach ulcer (painful sore). This side effect can occur when aspirin or NSAIDs are taken on their own. Taking these drugs with Pulmicort increases your risk of a stomach ulcer even more.

If you’d like to use an OTC pain reliever with Pulmicort, talk with your doctor or pharmacist. They may recommend you use Tylenol instead of aspirin, ibuprofen, or naproxen.

But if you’d prefer to use aspirin or an NSAID, your doctor or pharmacist can tell you how long it’s safe to take these drugs with Pulmicort. They’ll likely suggest you use aspirin or an NSAID for the shortest amount of time needed to treat your condition. Doing so will reduce your risk of a stomach ulcer.

Taking certain steps can help you avoid interactions with Pulmicort. Before starting treatment, talk with your doctor and pharmacist. Things to discuss with them include:

It’s also important to read Pulmicort’s label and other paperwork that comes with the drug. You may see colored stickers on the label that describe interactions. And the paperwork (sometimes called the prescribing information) may have other details about interactions. If you need help understanding this information, your doctor or pharmacist can help.

Using Pulmicort exactly as prescribed can also help prevent interactions.

If you still have questions about Pulmicort and its possible interactions, talk with your doctor.
