Methotrexate and mouth side effects

Posted Sat 11 Oct 2025 08.37 by Flynn

Anyone experienced mouth sores, dry mouth with methotrexate? Am on 12.5mg injections. Take folic acid 6 days. Been on methotrexate for over 10 years. Have psoriasis and psoriatic arthritis.

Yes. Have been on mtx for over 10 yrs. now been advised to stop (not taken for 4 weeks) but dry & sore mouth still persist. Could it be the psoriasis itself or a lingering side effect? Have appointment with dermatology next week.
