When checking interaction based on authoritative sources Drugs.com, Rxlist.com, Webmd.com, Medscape.com there are contraindications or side effects that may cause harm or increase the negative effect from drug use in presence of concomitant diseases.

Consumer:

The use of trimethoprim is contraindicated in patients with documented megaloblastic anemia due to folate deficiency. Trimethoprim inhibits dihydrofolate reductase, an enzyme necessary in the synthesis of tetrahydrofolic acid, or the metabolically active form of folic acid. Thrombocytopenia, neutropenia, megaloblastic anemia, and methemoglobinemia have been reported rarely. However, the risk is increased in the presence of folate deficiency, chronic hemolytic anemia and/or renal impairment, as well as during prolonged therapy (e.g., > 6 months) with high dosages. Therapy with trimethoprim should be administered cautiously under these conditions and in patients with suspected folate depletion (e.g., elderly, alcoholic, malnourished or debilitated patients). Folic acid supplementation, if necessary, may be administered concomitantly without interfering with the antibacterial action of trimethoprim. Patients should be instructed to immediately report any signs or symptoms suggestive of hematologic toxicity such as fever, sore throat, local infection, bleeding, pallor, dizziness, or jaundice. Leucovorin (folinic acid) should be administered if bone marrow depression is detected.
