I'm on 2 different ones, can't for the life of me remember their names but was told they are completely safe to use and one of them is a very strong steroid one. I have however been told I need more check ups to make sure I will be able to cope with my lungs getting squished as baby gets bigger and during labour so have a chat with your doctor about it all :)
I needed a refill last month on mine and my Dr gave me my normal alburtrall(sp) but its always good to ask Ur Dr. U can also ask the pharmacy where u get it fill if its safe. They have a system where they can look it up.
They woukdnt let my use some of my inhalers and meds so its best to check with your doctor x
My dr switched out some of my inhailers so definately ask! Good luck :)
You need to ask your doctor.. And have your doctor give you a prescription for one.
