Hi... Welcome to HEALTHCARE MAGIC.. I have gone through your query and can understand your concerns... As per your complain burning sensation of tongue along with pain can be due to a side effect of Cyclosporine which is an immuno-suppresant drug and is given to organ transplant patients to prevent tissue/organ rejection by the body. Cyclosporine can cause a dry mouth due to reduced watery secretions from the salivary glands and dry mouth in long term can cause burning mouth.. Tongue is the first organ that is affected and the patient experiences burning in tongue but any confirmed diagnosis can be given only after a thorough clinical evaluation and you should consult your treating doctor and explain the immediate symptoms and if cyclosporine is considered to be causing it,reduction in dose of medicine can be done to relieve the symptoms.. Other causes can be treated according to diagnosis.. As of now she can take a supportive treatment. Gargle with a numbing mouthwash containing Lignocaine to relieve the burning. Suck ice pops and do cold water rinses. Avoid spicy and hot foods.. Chew sugar-free chewing gums as it help in stimulating saliva flow.. Maintain a good oral hygiene. Take multivitamin supplements.. Hope this information helps.. Thanks and regards. Dr.Honey Nandwani Arora.
