Guest guest Posted December 18, 2007 Report Share Posted December 18, 2007 MTX can cause mouth sores. Or, rather, MTX interferes with the absorption of folic acid and the deficiency of folic acid causes the oral ulcers. You should have been given a prescription for a very large dose of folic acid to take along with the MTX. Most people take 1-5 mg (milligrams) a day to control the oral ulcers. The usual dose of FA is measured in micrograms; you will need a prescription-strength dose. If you were prescribed FA, you can increase the dose safely up to (usually) about 3 mg until the sores subside. Of course, you should check with your Dr. before doing so. When you call, ask what the max dose you should take is. My Dr. said up to 3 mg but other people here have taken up to 5. Best to ask up front how high you can go, so you don't have to keep calling. If you were not prescribed FA, call the Dr. right away and tell them you are having trouble with your mouth and that you understand you may need prescription-strength folic acid. best regards, sherry z --- In , " vjrademacher " Hi, Just a few questions to those of you who have had experience with methotrexate. He's giving me 2.5 mg per week for three weeks, then 5 mg per week for 2 weeks then 7.5 mg after that. I know 2.5 mg isn't much but my mouth feels kinda weird after taking it yesterday.

Guest guest Posted December 18, 2007 Report Share Posted December 18, 2007 I take folic acid 1 mg each day to counteract ulcers in the mouth. Are you taking folic acid? Sharon Quote Link to comment Share on other sites More sharing options...
Guest guest Posted December 18, 2007 Report Share Posted December 18, 2007 I haven't heard of anything about the mouth feeling weird. My son hasn't ever mentioned that either. He just complained of a stomach ache the day after he took it. We increased the amount of folic acid he was taking and now he has no stomach pain. & Grant/10 PsA/Uveitis --- In , " vjrademacher " Hi, Just a few questions to those of you who have had experience with methotrexate.

Guest guest Posted December 21, 2007 Report Share Posted December 21, 2007 If you are only feeling weird in your mouth, consider yourself lucky. I was vomiting and had constant nausea and migraine headaches. I was taken off it immediately. I am now on sulfasalasine with no problems. Isn't it so strange when our bodies are all so different?

Guest guest Posted December 26, 2007 Report Share Posted December 26, 2007 Sharon, see if your rheumy will write you a script for the 1 mg prescription tabs. They are on the $4 list at Walmart and ended up being cheaper for me than the OTC ones!
