Can I use berberine for mycosis of the tongue if Nystatin does not work?

If you are not helped by a prescription drug such as Nystatin, then - to the best of my knowledge - plant-based preparations, e.g. berberine, will not help. There is no point in using them. Please see a doctor - the range of antifungal drugs is wide - perhaps you should use a systemic drug, e.g. tablets in combination with topical therapy. After a thorough examination of the tongue, the doctor will be able to suggest an alternative treatment. Please remember - to recommend any preparation, first of all you need to see the affected place - this is the basis. The selection of prescription drugs, in particular, if the actual current therapy is a failure, should be agreed with the doctor and undoubtedly carefully thought out on the basis of your medical records. Pharmacists do not choose prescription drugs and do not specialize in diagnosing or treating ringworm of the tongue - this is the competence of the doctor, and this type of drugs are available only on prescription. We are also not allowed to advertise or recommend prescription drugs, but we can provide information about pharmacotherapy if such drugs are used by the patient on the recommendation of a doctor.
