What happens if i take bactrim while malnourished?

Hypoglycemia is rare: "Cases of hypoglycemia in non-diabetic patients treated with BACTRIM are seen rarely, usually occurring after a few days of therapy. Patients with renal dysfunction, liver disease, malnutrition or those receiving high doses of BACTRIM are particularly at risk."

Sulfa: Why are you malnourished? Your taking Bactrim, which has a sulfa component, may not be contraindicated, but make sure you drink at least 2 quarts of water per 24 hours while on that medication so you'll have strong urine output.. You must also address this problem of malnourishment with your physician.
