| Treatment of sporotrichosis depends on the severity and location of the disease. The following are treatment options for this condition:<ref>{{cite journal |author=Lortholary O, Denning DW, Dupont B |title=Endemic mycoses: a treatment update |journal=J. Antimicrob. Chemother. |volume=43 |issue=3 |pages=321–31 |year=1999 |pmid=10223586 |url=http://jac.oxfordjournals.org/cgi/content/full/43/3/321 |doi=10.1093/jac/43.3.321}}</ref>

|
| *Saturated [[potassium iodide]] solution
| |
| :Although its mechanism is unknown, application of potassium iodide in droplet form can cure cutaneous sporotrichosis. This usually requires 3 to 6 months of treatment.
| |
|
| |
| *[[Itraconazole]] (Sporanox) and [[fluconazole]]
| |
| :These are [[Antifungal medication|antifungal]] drugs. Itraconazole is currently the drug of choice and is significantly more effective than fluconazole. Fluconazole should be reserved for patients who cannot tolerate itraconazole.
| |
| *[[Amphotericin B]]
| |
| :This antifungal medication is delivered intravenously. Many patients, however, cannot tolerate Amphotericin B due to its potential side effects of fever, nausea, and vomiting.
| |
| Lipid formulations of amphotericin B are usually recommended instead of amphotericin B deoxycholate because of a better adverse-effect profile. Amphotericin B can be used for severe infection during pregnancy. For children with disseminated or severe disease, amphotericin B deoxycholate can be used initially, followed by itraconazole.<ref name="dbt.consultantlive.com">Hogan BK, Hospenthal DR. [http://dbt.consultantlive.com/display/article/1145628/1545568 Update on the therapy for sporotrichosis]. Drug Benefit Trends. 2010;22:49-52.</ref>
| |
|
| |
| :In case of sporotrichosis meningitis, the patient may be given a combination of Amphotericin B and 5-fluorocytosine/[[Flucytosine]].
| |
|
| |
| *Newer [[triazole]]s
| |
| Several studies have shown that [[posaconazole]] has in vitro activity similar to that of amphotericin B and itraconazole; therefore, it shows promise as an alternative therapy. However, [[voriconazole]] susceptibility varies. Because the correlation between in vitro data and clinical response has not been demonstrated, there is insufficient evidence to recommend either posaconazole or voriconazole for treatment of sporotrichosis at this time.<ref name="dbt.consultantlive.com"/>

| *[[Surgery]]
| |
| :In cases of bone infection and cavitatory nodules in the lungs, surgery may be necessary.
