Sometimes, certain factors or conditions could prevent your doctor from prescribing Trelegy Ellipta due to the risk of harm. These are known as contraindications. The contraindications of Trelegy Ellipta include:

Treating status asthmaticus or sudden worsening of COPD

Trellegy Ellipta should not be used as a treatment for status asthmaticus or a sudden worsening of COPD (COPD exacerbation). Trelegy Ellipta is not a rescue inhaler, and does not work quickly enough to treat a sudden worsening of COPD or asthma symptoms.

Follow your doctor’s advice on using your rescue inhaler for an asthma attack or worsening COPD symptoms. If your symptoms feel severe or life-threatening, seek immediate medical attention.

Having had an allergic reaction to Trelegy Ellipta or any of its ingredients, including milk proteins

If you have had an allergic reaction to Trelegy Ellipta or any of its ingredients, which includes milk proteins (dairy allergy), your doctor will likely not prescribe Trelegy Ellipta. Taking the drug could cause another allergic reaction. You can ask them about other treatments that may be better choices for you.

Note:Before you start treatment with Trelegy Ellipta, it’s important to tell your doctor if these contraindications apply to you. They can determine whether to prescribe Trelegy Ellipta.

There are no known interactions between Trelegy Ellipta and alcohol. However, your doctor may advise you to avoid or limit alcohol consumption during Trelegy Ellipta treatment.

This is because drinking alcohol can worsen the condition you’re receiving Trelegy Ellipta to treat. For example, if you have chronic obstructive pulmonary disease, drinking alcohol may worsen your symptoms.

If you have questions about drinking alcohol during Trelegy Ellipta treatment, talk with your doctor.

Here’s a closer look at certain drug interactions of Trelegy Ellipta.

Beta blockers

Trelegy Ellipta can interact with beta-blockers. These medications are prescribed for certain conditions including high blood pressure, heart failure, and arrhythmia.

Interaction result:Taking Trelegy Ellipta with a beta-blocker can make Trelegy Ellipta less effective.

Interaction explained:Trelegy Ellipta contains vilanterol as one of its active ingredients. Vilanterol is a type of medication called a beta agonist. It works by activating beta receptors in your lungs. Beta-blockers can block vilanterol from working, which means Trelegy Ellipta may not work as well if taken with a beta-blocker.

It’s important to note that some beta-blockers are considered “cardioselective”. This means they mostly block beta receptors in the heart and not in the lungs. However, cardioselective beta-blockers can still affect beta receptors in the lungs, especially at higher doses.

Examples of beta-blocker drugs: Here are some beta-blocker drugs that may interact with Trelegy Ellipta:

Steps you or your doctor may take:If you’re prescribed Trelegy Ellitpa and need to take a beta-blocker as well, your doctor may switch you to a cardioselective beta-blocker such as atenolol or metoprolol. While cardioselective beta-blockers still have a risk for interacting with Trelegy Ellipta, this risk is lowered compared to using a noncardioselective beta-blocker such as propranolol or carvedilol. Your doctor will also likely closely monitor you to ensure Trelegy Ellipta is working as expected.

Anticholinergic medications

Trelegy Ellipta can interact with anticholinergic medications. These medications are prescribed for a variety of conditions, including overactive bladder and certain symptoms of Parkinson’s disease.

Interaction result: Taking Trelegy Ellitpa together with an anticholinergic medication can increase the risk for certain side effects of Trelegy Ellipta and anticholinergic medications, including:

Interaction explained: Trelegy contains umeclidinium, which is an anticholinergic medication. Taking another anticholinergic medication together with Trelegy increases your risk for anticholinergic side effects that either medication can cause.

Examples of anticholinergic drugs: Here are some anticholinergic drugs that may interact with Trelegy Ellipta:

  • diphenhydramine (Benadryl)
  • oxybutynin (Ditropan XL)
  • benztropine
  • trihexyphenidyl
  • scopolamine

Steps you or your doctor may take: Due to the risk for side effects, doctors typically avoid prescribing Trelegy Ellipta together with another anticholinergic medication. If prescribing this combination cannot be avoided, your doctor will likely closely monitor you for anticholinergic side effects.

Certain diuretics

Trelegy Ellipta can interact with certain diuretics. These medications are prescribed to treat conditions such as high blood pressure, and edema (fluid buildup) caused by conditions such as liver disease or heart failure.

Interaction result: Taking Trelegy Ellitpa together with certain diuretics can increase the risk for certain side effects of certain diuretics and Trelegy Ellipta.

Interaction explained: Certain diuretics can cause low blood potassium (hypokalemia) or affect your heart rhythm as a side effect. These side effects can worsen if you also take a beta agonist medication. And, Trelegy Ellipta contains the beta agonist vilanterol.

Examples of diuretic drugs: Here are some diuretics that may interact with Trelegy Ellipta:

  • loop diuretics, such as:
    • furosemide (Lasix)
    • bumetanide (Bumex)
    • torsemide (Soaanz)
  • thiazide diuretics, such as:

Steps you or your doctor may take: Although Trelegy Ellipta and certain diuretics may interact, doctors still commonly prescribe these medications together. Your doctor can monitor this interaction and may order an electrocardiogram (ECG or EKG) and blood tests to check your potassium level. Your doctor can provide more information, such as how often they’ll order these tests during your treatment.

Because of this interaction, your doctor will likely recommend limiting how much caffeine you consume during Trelegy Ellipta treatment.

Grapefruit and grapefruit juice can interact with Trelegy Ellipta. Specifically, grapefruit products can stop your body from breaking down Trelegy Ellipta. This raises the level of Trelegy Ellipta in your body, which increases your risk of side effects from Trelegy Ellipta Due to this risk, your doctor may recommend not consuming grapefruit and grapefruit juice while taking the drug.

If you’d like to learn more about eating certain foods during treatment with Trelegy Ellipta, talk with your doctor.

Trelegy Ellipta interactions with vaccines

There are no known interactions between Trelegy Ellipta and vaccines. Talk to your doctor or pharmacist to see whether you’re due for any vaccines.

Trelegy Ellipta interactions with lab tests

Trelegy Ellipta may interact with the tuberculin purified protein derivative (PPD) test (also called a tuberculosis skin test), which is used to test for tuberculosis (TB). Using Trelegy Ellipta may cause a false-negative test result, meaning the test doesn’t show TB even if you actually have it. This effect may last for up to 6 weeks after your last dose of Trelegy Ellipta.

If you need a test for TB, your doctor may choose an alternative besides the skin test if you’re using Trelegy Ellipta.

TRELEGY ELLIPTA INTERACTION WITH CANNABIS OR CBD

Cannabis (often called marijuana) and cannabis products, such as cannabidiol (CBD), have not been specifically reported to interact with Trelegy Ellipta. Some research suggests smoking cannabis may not carry as high as risk for developing COPD compared to smoking tobacco. But any smoke is damaging to your lungs, regardless of whether it comes from tobacco or cannabis. So, smoking cannabis could still worsen COPD or asthma symptoms if you already have either condition.

As with any drug or supplement, talk with your doctor before using cannabis in combination with Trelegy Ellipta. The impact of cannabis may affect how well you stick to your Trelegy Ellipta treatment plan.

Note: Cannabis is illegal at a federal level but is legal in many states to varying degrees.
