moderate Known Drug Interaction
May potentiate effect of formoterol fumarate on cardiovascular system. ( 7.6 ) 7.1 Adrenergic Drugs If additional adrenergic drugs are to be administered by any route, they should be used with caution because the sympathetic effects of formoterol, a component of BEVESPI AEROSPHERE, may be potentiated [see Warnings and Precautions (5.3) ] . 7.2 Xanthine Derivatives, Steroids, or Diuretics Concomitant treatment with xanthine derivatives, steroids, or diuretics may potentiate any hypokalemic effect of beta 2 adrenergic agonists such as formoterol, a component of BEVESPI AEROSPHERE.

Bevespi Aerosphere
Formoterol is a medicine that helps open your airways. It is used to make breathing easier for people with COPD.
Bevespi Aerosphere is a medicine that helps people with COPD breathe easier. It contains two medicines that work together to open airways.
Formoterol inhalation solution is used to treat chronic obstructive pulmonary disease (COPD). COPD includes chronic bronchitis and emphysema. This medicine helps to lessen the tightening of your airways, making it easier to breathe. It is for long-term use and should be taken twice a day.
Bevespi Aerosphere is used to help manage chronic obstructive pulmonary disease (COPD). COPD is a long-term lung disease that makes it hard to breathe. This medicine helps to open your airways so you can breathe easier. It is not for sudden breathing problems.
Formoterol is a long-acting beta-2 agonist (LABA). It works by relaxing the muscles around your airways. This allows more air to flow in and out of your lungs.
This medicine combines two drugs: glycopyrrolate and formoterol. Glycopyrrolate is an anticholinergic that relaxes the muscles around your airways. Formoterol is a LABA that also relaxes airway muscles, helping you breathe better.

If you have asthma, you should not take formoterol without also using an inhaled corticosteroid medicine. Using formoterol alone for asthma can increase the risk of serious asthma problems, including death. Do not use formoterol to treat sudden breathing problems. Always have a rescue inhaler with you to treat sudden symptoms.
LABA medicines like formoterol, when used alone for asthma, increase the risk of serious asthma problems. Bevespi Aerosphere is only for COPD, not asthma. Do not use Bevespi Aerosphere if you have asthma.
Tell your doctor if you are pregnant or plan to become pregnant. It is not known if formoterol will harm your unborn baby. Talk to your doctor about the risks and benefits of using formoterol during pregnancy. It is also not known if formoterol passes into breast milk.

How to Read This formoterol vs glycopyrrolate/formoterol Comparison
formoterol is classified in the Long-Acting Beta-2 Agonist (LABA) drug class, while glycopyrrolate/formoterol sits within the LAMA / LABA Combination class. Drugs from different classes work through distinct mechanisms, so a head-to-head comparison illustrates trade-offs rather than equivalence. Both drugs are prescription-only, so a licensed provider must authorize use.
Adverse event totals above are pulled from the FDA's Adverse Event Reporting System (FAERS). For these top-ranked reactions alone, formoterol has 3,671 submissions while glycopyrrolate/formoterol has 3,631. Those figures reflect cumulative reporting volume, not per-patient risk, so older, widely dispensed drugs typically look worse on count alone. These two drugs have a known moderate interaction flagged in FDA labeling, attributed to taking two drugs that work the same way can cause a stronger effect on your heart and nervous system. this happens because both drugs stimulate the same receptors in your body.. Serious warnings, pregnancy guidance, and contraindications can differ even when indications overlap.
A table cannot represent individual circumstances. Data here is sourced from FDA Structured Product Labels (SPL) and FAERS, both of which update as manufacturers and clinicians submit new information. This registry does not provide medical, treatment, substitution, or medication-change directions for formoterol or glycopyrrolate/formoterol.
