Special Considerations
Drugs that may increase urine glucose measurements include aminosalicylic acid, cephalosporins, chloral hydrate, chloramphenicol, dextrothyroxine, diazoxide, diuretics (loop and thiazides), estrogens, isoniazid, levodopa, lithium, nafcillin, nalidixic acid, and nicotinic acid (large doses).
Drugs that may give false positive results with Clinitest, but not with the dipstick tests, include acetylsalicylic acid, aminosalicylic acid, ascorbic acid, cephalothin, chloral hydrate, nitrofurantoin, streptomycin, and sulfonamides.
Drugs that may give false negative results are ascorbic acid (dipstick tests such as Clinistix, Tes-tape), levodopa (Clinistix), and phenothiazines (Clinistix, Tes-tape).
