Just a bit of info needed if you can help!

Glynis there is a Seretide 500 inhaler, so if your GP wanted to double up on your current inhaler, that would be fine!

Hi,

I'm on Seretide 250x2puffs twice a day. 2x250 gives the same steroid dose as 1x500 but gives you double salmeterol (than the 500), I believe, I'm no expert. I think the drugs you get are 50(salmeterol )/250 or 50(salmeterol )/500.

Someone with a 500 might be able to confirm whats in that one? Apologies if I've got it wrong!

Seretide 500 (an accuhaler) is actually 500mcg fluticasone & 50mcg salmeterol with the dose being one puff twice a day so it is actually a dry powder equivalent of seretide 250 evohaler (250mcg fluticasone & 25mcg salmeterol) 2 puff twice a day. You are actually on the maximum *licensed* dose of seretide, but it is not unheard of for doctors to exceed licensed doses of medicines where the benefits outweigh any risks.

EDIT: For clarifcation the Seretide accuhaler dose is 500/50 (1 puff twice a day) and Seretide evohaler dose is 250/25 (2 puffs twice a day).

I use the seretide 500 accuhaler as metered dose inhalers (AKA sprays/puffers) make me worse.

They don't make this easy do they!

Mine is the Seretide 250 accuhaler, which has 50 salmeterol and 250 of the steroid. Now I'm wondering why they're different?

@TS all the seretide accuhalers are intended to be one puff twice a day, while the seretide evohalers are intended to be two puffs twice a day which is why the ratios are different.

Thanks Nimueh. It all makes sense now
