Umeclidinium-vilanterol (Anoro Ellipta): what it treats, how to take it, side effects
Last updated September 3, 2026.
Umeclidinium-vilanterol (brand name Anoro Ellipta) is a once-daily maintenance inhaler for COPD. It combines two long-acting bronchodilators, an anticholinergic and a LABA, in one device to keep airways open around the clock.
What does it treat?
It is for the long-term maintenance treatment of chronic obstructive pulmonary disease, including chronic bronchitis and emphysema. Two things it is not for: it does not relieve sudden breathing attacks (that is what a rescue inhaler is for), and it is not indicated for asthma, because a LABA used without an inhaled steroid raises the risk of serious asthma events.
How do you take it?
One inhalation once a day, at the same time each day, and no more than that: each actuation delivers 62.5 mcg umeclidinium and 25 mcg vilanterol, built to last 24 hours. Slide the cover open until it clicks (that loads the dose), breathe out away from the device, seal your lips on the mouthpiece, and take one long, deep, steady breath in, then hold for a few seconds. Do not shake it, and close the cover after. If you miss a dose, take it when you remember, but never take more than one inhalation in a day.
Side effects to know
- Common: sore throat, sinus infection, lower respiratory infection, constipation, diarrhea, muscle spasms, and pain in an arm or leg.
- Serious: paradoxical bronchospasm, new or worsening narrow-angle glaucoma or urinary retention (especially with an enlarged prostate), fast or irregular heartbeat, low potassium, and serious allergic reactions.
Who should not take it?
Do not use it if you have a severe allergy to milk proteins or any ingredient, and do not combine it with another LABA-containing medicine, which risks overdose. It is contraindicated in asthma unless an inhaled corticosteroid is also in use. Caution applies with heart rhythm problems, high blood pressure, seizures, an overactive thyroid, diabetes, glaucoma, and prostate or bladder-neck problems. Pregnancy decisions belong with your doctor.
When is it an emergency?
Call 911 if breathing tightens right after a dose, if your face or throat swells or you cannot breathe easily, or for chest pain with a racing irregular heartbeat. Sudden eye pain with blurred vision or halos, or being unable to urinate, also need same-day emergency care. Pymander's escalation routing is built and tested specifically for this class of decision; see the safety architecture working paper.

Common questions
Is Anoro a rescue inhaler?
No. Anoro Ellipta is a once-daily maintenance inhaler that works over 24 hours to keep airways open. It starts too slowly to treat a sudden attack, and using extra doses during one is dangerous. Keep a short-acting rescue inhaler for acute symptoms.
Can I use Anoro for asthma?
No. It is not indicated for asthma, and the label contraindicates using a LABA like vilanterol without an inhaled corticosteroid in asthma patients because of the risk of severe asthma events. Asthma needs its own regimen, usually built around inhaled steroids.
What do the two ingredients each do?
Umeclidinium is an anticholinergic that blocks the signal tightening airway muscle, and vilanterol is a long-acting beta-agonist that actively relaxes it. They open airways by two different routes, which is why the combination controls COPD symptoms better than either alone for many patients.
How do I know I actually inhaled the dose?
The Ellipta powder is fine and tasteless, so most people feel nothing, and that is normal. Trust the mechanics: the counter clicked down one number, you heard the cover click open before inhaling, and you took a long deep breath. Do not take a second puff to check; that doubles the dose.
Does Anoro interact with my other inhalers?
The key rule is no doubling up on the LABA ingredient: do not use Anoro alongside another long-acting beta-agonist inhaler such as salmeterol or formoterol. Inhaled steroids and short-acting rescue inhalers are fine to continue. Bring all your inhalers to your appointments.
Will it affect my prostate or glaucoma?
It can. The anticholinergic component can worsen urinary retention in men with prostate enlargement and can precipitate narrow-angle glaucoma. New trouble urinating, or sudden eye pain with halos around lights, needs prompt medical attention.
