Can advair cause headaches?

Maybe yes: Many medications list headaches as a possible side effect. However, headaches are common in people, whether or not they are taking medication. If one gets headaches right after each dose of advair, advair may well be the cause. Advair has 2 ingredients, so one can try them individually to see if either cause a headache. One can also ask to try symbicort, (budesonide and formoterol) which is a little different from advair.

It's Possible: The only way to know is to either stop the advair or switch to a different inhaler depending on the severity of your asthma or lung disease.

Not typically: Advair won't typically cause headaches, but if you have rule out all other potential causes, you may just stop it for a few days or switch to a different similar preparation and see if that makes a difference. I'd consult with your doc first, though, because stopping advair on your own may cause your asthma to flare up, so you will need a back up plan if you stop it.

Guess it's possible: However, this isn't a complaint I've received from Advair.
