Asthma and COPD meds are a tough crowd. One day you’re used to your inhaler, and then—bam—you’re staring at a new purple disk with different numbers. Lots of people hear that their insurance dropped their trusty Symbicort or that Advair’s on sale and wonder what’s going to hit them next. Making the move between these two can feel like learning to drive again, but with a few pointers, you can skip most of the stress. There’s no magic, but there’s definitely a method to not getting caught off guard.
Switching meds isn’t just a matter of swapping one inhaler for another. Symbicort and Advair aren’t identical twins—they’re more like cousins with a lot in common but some key differences. Both are combination inhalers used to keep airways calm for folks with asthma or COPD, but the drugs inside, dosages, and devices set them apart.
Symbicort combines budesonide (a corticosteroid) and formoterol (a fast-acting long-acting beta-agonist, or LABA). Advair’s mix is fluticasone propionate (a different corticosteroid) and salmeterol (a slower-onset LABA). The speed at which formoterol acts versus salmeterol matters. Formoterol can start working in a few minutes, so some people use Symbicort as both a maintenance and rescue inhaler (ask your doctor if you’re one of them; not all asthma plans recommend this). Advair isn’t for sudden attacks, period.
Here’s a quick breakdown in a table for matching up those active ingredients and delivery devices:
Inhaler | Corticosteroid | LABA | Device | Onset |
---|---|---|---|---|
Symbicort | Budesonide | Formoterol | Metered-dose (MDI) | Within minutes |
Advair | Fluticasone Propionate | Salmeterol | Dry Powder Inhaler (Diskus) or MDI | Within 30+ minutes |
Each person may react differently to the corticosteroids, too. Fluticasone is a little stronger by the microgram, which plays into how doctors swap one dose to another—not just a 1:1 switch. This isn’t split-second math and why it pays to speak up about any changes you feel when you swap.
Here’s where most people get tripped up: your Symbicort dose isn’t the exact same as what you’ll need from Advair. It would be great if you could just grab the same number of puffs, but fluticasone vs budesonide means you’re not comparing apples to apples.
Doctors usually try to match the corticosteroid "strength" (also called the equivalent corticosteroid dose) as closely as possible. For example, if you’ve been taking Symbicort 160/4.5 (that’s 160 mcg of budesonide and 4.5 mcg of formoterol per puff) two puffs twice daily, that’s 640 mcg daily of budesonide. Most people moving to Advair Diskus, for similar control, might get Advair 250/50 (250 mcg fluticasone, 50 mcg salmeterol) one puff twice daily. But here’s the kicker: fluticasone packs a punch even at a lower number, so you can’t just go by the label.
It usually takes about a week to feel the full effect after switching, and don’t be surprised if you need what feels like a “weird” dose for a while during the overlap. If your insurance switches you out in the middle of a 90-day supply, keep both inhalers labeled in your cabinet so you don’t mix them up.
Not sure how your options stack up, or looking for more alternatives? Here’s a helpful take from someone who went through switching from Symbicort to Advair and tried other routes in 2025. Some outside-the-box choices might surprise you.
This is where real life kicks in. Some folks barely notice the change after switching to Advair; others hit every bump in the road. It’s not just about dry mouth or a cough—sometimes, you’re suddenly waking up more at night, or you feel jittery after using your inhaler.
The first month is when most shake-ups happen. If anything feels way off—your heart races, you get dizzy, or can’t breathe well—skip guessing and call your doctor. Don’t wait until your next routine visit. Most inhaler side effects are mild, but asthma control is non-negotiable. If you’re reporting back to your doc, mentioning specific symptoms with dates is gold.
One sneaky habit? Some people unconsciously use their inhaler differently, especially if you’re going from an MDI to a Diskus (or vice versa). The Diskus is breath-activated; you need a strong, fast inhale to activate it. That takes practice, especially for kids or older adults used to slow puffs. Your asthma nurse or pharmacist can coach you—don’t be shy about asking for a demo.
Here’s a quick guide on expected vs red-flag symptoms after a switch:
Expected Side Effect | What To Do |
---|---|
Dry mouth / hoarse voice | Rinse/spit; use throat lozenges |
Mild cough after inhaling | Try a spacer or rinse mouth; usually fades |
Slight increase in need for rescue inhaler (first week) | Monitor with peak flow; talk to doc if it continues |
White patches in mouth | See doctor; may need antifungal |
Heart palpitations, weakness, worsening asthma | See doctor ASAP |
Few things are more annoying than learning your insurance suddenly won’t cover your old inhaler. Prior authorizations are meant to make sure you’re getting the "right" medicine for your needs and their costs, but in reality, they can feel like a paperwork mess.
Start by getting your doctor’s office involved early. Most clinics have a workflow just for dealing with prior authorizations. Let them know your insurance has changed, and which inhaler you’ll need—don’t assume the pharmacy will catch it.
Kids sometimes need extra paperwork, and for anyone with both asthma and COPD, insurers may want details or specialist notes. If you have travel plans, get extra lead time—you don’t want to get stuck abroad without the right inhaler type.
By now, you can see switching from Symbicort to Advair isn’t as quick as ditching ketchup for mustard. It involves talking to your doc, reading up, and sometimes, being your own best advocate at the pharmacy. If you catch side effects early, match your dose sensibly, and get a handle on the insurance game, you’ll make the leap with way fewer surprises. It’s all about knowing what you’re getting, how to use it, and staying alert if your body tells you it’s time to tweak things again.

In a recent blog post, I discussed the link between high eye pressure and glaucoma, a potentially blinding eye disease. I learned that high eye pressure, also known as ocular hypertension, can damage the optic nerve and lead to glaucoma. It's important to have regular eye exams to detect any changes in eye pressure early on. While not everyone with high eye pressure will develop glaucoma, it is still a significant risk factor. Therefore, it's essential to be proactive in managing eye pressure and maintaining overall eye health.
