Final answer:
For a burn-like sensation on the tongue with a positive smear for yeast and fungal organisms, antifungal medications such as nystatin, clotrimazole, fluconazole, or itraconazole are typically prescribed, depending on the severity and resistance of the infection.
Step-by-step explanation:
If a patient with chronic asthma who had an infection and was treated with tetracycline is now complaining of a burning tongue, and a smear reveals the presence of yeast and fungal organisms, the treatment would involve antifungal medication. Given that tetracycline can disrupt the balance of normal microbiota and promote overgrowth of opportunistic fungi such as Candida albicans, an appropriate approach to alleviate the patient’s symptoms may include the use of antifungal agents. A typical choice for oral fungal infections, or oral thrush, is to prescribe topical antifungals like nystatin or clotrimazole oral suspensions. However, for more severe infections or if the strain is resistant to these options, systemic treatment with azoles such as fluconazole or itraconazole might be necessary. In extremely severe or resistant cases, amphotericin B could be considered. It is also important to investigate and manage any underlying conditions that may have contributed to the proliferation of the fungal infection.
