Cimzia/methotrexate/hydroxy = coldsores and mouth sores

I am quite used to my mouth shedding skin and having an occasional sore inside my mouth but since starting Cimzia a few months ago, am getting a recurring coldsore and more mouth sores than before (on the positive side, my joints feel much better, as do my energy levels). I am due to see rheumatology sister next month but wondered if meantime anyone has any tips to help combat them? My sister is a nurse and would normally recommend antivirals for recurring coldsores but don't think this is an option to be explored with being on immuno suppressants. Thank you for any advice.

When well established on the Cimzia it may be possible for you to decrease the amount of methotrexate(MTX) /hydroxy you take which will probably bring up your level of immunity decreasing or eliminating the number of cold sores and mouth sores you get.

I was getting an increasing number of infections, cold sores and mouth sores so asked my consultant if I could continue with Enbrel but try dropping the MTX. It's still working very well by itself and I've had no further cold sores/mouth sores. I would be happy to add a smaller dose of another DMARD if it was thought necessary in the future. It's probably a question of getting the right amount and combination/balance of drugs for each individual. Perhaps something to discuss with your rheumy team.


That's interesting, thank you for the reply - yes am still on 20 mg methotrexate jabs weekly so it might be possible to reduce the dose. Cimzia has definitely made a big difference thankfully, glad Enbrel has for you!
