Just a quick thankyou to everyone who's been in touch since I asked about taking Omeprazole with Celecoxib - I spoke to our pharmacist earlier and he says yes, I can definitely take Omep. And, since I still have a supply of 20mg ones left over from a few months back, I'm sorted! Obviously I'll check with GP too but no mad panic today. So that's me on Methotrexate injections 15mg, Celecoxib 100mg twice a day, and now Omeprazole 20mg. Thank you all for help and advice, and if at all possible, have a good Christmas.
