Drug Interaction

Cefaclor can potentially interact with other drugs, which can affect its effectiveness, increase the risk of side effects, or alter the way it is metabolized in the body. Here are some important interactions to be aware of:

  • Probenecid: Probenecid can delay the excretion of Cefaclor from the body, potentially leading to increased drug levels and an increased risk of side effects.
  • Antacids: Some antacids containing aluminum or magnesium hydroxide can reduce the absorption of Cefaclor, so it's recommended to take them at least 1 hour before or 2 hours after taking tablets.
  • Iron Supplements: Iron supplements can also reduce the absorption of Cefaclor, so it's advisable to separate the doses by a few hours.
  • Oral Contraceptives: There have been reports of decreased effectiveness of hormonal contraceptives (birth control pills) when taken concomitantly with antibiotics like Cefaclor. This can potentially lead to unintended pregnancies. It's recommended to use alternative methods of contraception during cefaclor treatment.
  • Nephrotoxic Drugs: Cefaclor can have potential interactions with nephrotoxic drugs, like aminoglycoside antibiotics and certain diuretics, which could increase the risk of kidney damage.
  • Warfarin: There have been reports of Cefaclor potentially increasing the effects of warfarin (a blood thinner), leading to an increased risk of bleeding. Close monitoring of blood clotting parameters is advised if these medications are taken together.
  • Lactulose: Cefaclor may cause false-positive results in certain tests for sugar in the urine, such as the Benedict's solution, Fehling's solution, or Clinitest tablets. Lactulose, a medication used to treat constipation, can also cause false-positive results in these tests.
