Does Sulfamethoxazole And Trimethoprim Interact with Acetazolamide?
CDI records a major classification for Sulfamethoxazole And Trimethoprim and Acetazolamide. The stored summary is: Methotrexate Avoid concurrent use Sulfonamides can also displace methotrexate from plasma protein binding sites and can compete with the renal transport of methotrexate, thus increasing free methotrexate concentrations. Oral Hypoglycemics Monitor blood glucose more frequently Like other sulfonamide-containing drugs, BACTRIM potentiates the effect of oral hypoglycemic that are metabolized by CYP2C8 (e.g., pioglitazone, repaglinide, and rosiglitazone) or CYP2C9 (e.g., glipizide and glyburide) or eliminated renally via OCT2 (e.g., metformin). Patients taking both medications should consult their healthcare provider before starting, stopping, or changing the dosage of either drug. This record was extracted from drug labeling through openFDA. NIH/NLM RxNorm is used for drug identities. The summary and severity classification are CDI's processed information, not a verbatim source quotation. Product, route, and patient circumstances matter.
