Can Gildess interact with other medications or foods?

The birth control pill Gildess (norethindrone and ethinyl estradiol) is not known to interact with foods but may interact with other medications. Drugs that may interact with Gildess include:
  • antibiotics
  • some oral antifungal drugs
  • the tuberculosis drug rifampin (Rimactane, Rifadin)
  • ascorbic acid (vitamin C) in large amounts
  • acetaminophen (Tylenol)
  • the cholesterol drug atorvastatin (Lipitor)
  • anticonvulsants
This is just a partial list of drugs that may interact with Gildess. Some drugs can interfere with Gildess's effectiveness (possibly increasing your risk of pregnancy) or increase your chance of side effects. Others may become less effective if you're on Gildess. Before you start Gildess, tell your doctor about all your other medications (prescription and over-the-counter), as well as any vitamins or supplements you take. Once you're on Gildess, talk to your doctor before starting any new drug or supplement, and ask if you should use a backup form of birth control.
