Thiosulfil Forte (sulfamethizole) Disease Interactions

There is 1 disease interaction with Thiosulfil Forte (sulfamethizole):

Major

Sulfonamides (Includes Thiosulfil Forte) ↔ Hematologic Toxicity

Severe Potential Hazard, Moderate plausibility

Applies to: G-6-PD Deficiency

The use of sulfonamides has been associated with hematologic toxicity, including methemoglobinemia, sulfhemoglobinemia, leukopenia, granulocytopenia, eosinophilia, hemolytic anemia, aplastic anemia, purpura, clotting disorder, thrombocytopenia, hypofibrinogenemia, and hypoprothrombinemia. Acute dose-related hemolytic anemia may occur during the first week of therapy due to sensitization, while chronic hemolytic anemia may occur with prolonged use. Patients with glucose-6-phosphate dehydrogenase (G-6-PD) deficiency should be observed closely for signs of hemolytic anemia. Therapy with sulfonamides should be administered cautiously in patients with preexisting blood dyscrasias or bone marrow suppression. Complete blood counts should be obtained regularly, especially during prolonged therapy (>2 weeks), and patients should be instructed to immediately report any signs or symptoms suggestive of blood dyscrasia such as fever, sore throat, local infection, bleeding, pallor, dizziness, or jaundice.
