After having recurring mouth ulcers for nine years I have at last found relief.

I was prescribed a tetracycline mouth wash from a specialist which I had made up from a compounding pharmacist for about $90 a script. The mouthwash would last about five days but two days after I finished the ulcers would recur. I spent many nights lying in bed in pain in tune with my breathing.

I went back to my local GP a couple of weeks ago and he gave me a script for 100mg doxycycline capsules. I broke the capsule open and then smashed the capsules with the handle end of a spoon in a glass with 40ml water. (My version of a mortar and pestle).

I used this as a mouthwash twice a day and found my ulcers gone within 48 hours. I swirled the mouthwash around for about five minutes each time I used it.

I have not had them recurring for over two weeks now and to me this is simply a miracle. The cost of the tablets were about Australian $9.10 for 25 capsules.

I don’t know if this will work for other people as I realise that some people are allergic to antibiotics but if there are any others out there going through the pain I have gone through I can suggest you give it a try.

    Dear Janet, thank you for your kind reply. Since my last post I have also avoided highly spiced foods that include chilli or curry powder and I am still ulcer free. I find life so much better now as being in constant pain was also affecting my mental health. The love and support of my husband has been amazing and I don’t know how he puts up with me at times. May God look after you all. Love Linda xx

    Hi Linda,
    I hear you! I have suffered with canker sores all of my life. Some inhaled meds have caused repeated yeast infections, also known as thrush. I don’t know if we have experienced the same, but I do understand mouth sores and pain.
    I’t’s wonderful that you and your doctor found something that works for you. I did too.
    Thank you for sharing.

    Hi lindainoz and thanks for sharing your story with the community. Nine years is a long time to deal with the condition you described (mouth ulcers). I’m so glad you have resolved this in collaboration with your doctor.
    It’s good to hear you’re feeling so much better after all this time.
    Wishing you continued good health.
