I've had asthma for the last 20 years starting in my early 30's.
I've trialled many medications however not really had good control and needed lots of steroids to assist with exacerbation.
After s serious asthma attack three months ago I started theophylline, started on 200mg bd however this only gave me blood levels of 8 so the gp increased this to 500mgbd and this has brought my bloods up to 13
The meds are doing great for my chest and I've not had an attack since starting this ( take it with symbicort smary regime)
However since starting the 400mgbd dose I've had trouble with swollen painful legs
I also get a bit of nausea and headache but I see those are very recognised side effects but I can't see the leg pain or swelling as an issue,
It's so bad that it is potentially going to cause me to stop taking it
