Emergency contraceptives, such as Plan B and Ella, are not known to have any significant food-drug interactions. However, taking these medications with food may help reduce the risk of stomach upset or nausea. It is generally recommended to take emergency contraceptives as soon as possible after unprotected intercourse for maximum effectiveness.

Oral Emergency Contraceptives
- Antibiotics: Rifampin, rifabutin, griseofulvin, penicillins, cephalosporins, tetracycline - may decrease effectiveness of emergency contraceptives due to induction of drug-metabolizing enzymes in the liver.
- Anticonvulsants: Phenytoin, carbamazepine, oxcarbazepine, phenobarbital - may increase clearance of emergency contraceptives, reducing their effectiveness.
- HIV protease inhibitors: Ritonavir, saquinavir, indinavir, nelfinavir - may increase blood levels of emergency contraceptives, potentially leading to increased side effects.
- St. John's Wort: May decrease blood levels of emergency contraceptives, reducing their effectiveness.
Intrauterine Device (IUD)
- Antibiotics: Penicillins, cephalosporins, tetracycline - may increase risk of infection during IUD insertion.
- Anti-inflammatory drugs (NSAIDs): Aspirin, ibuprofen, naproxen - may increase bleeding and reduce the efficacy of the IUD.
- Estrogen-containing medications: Birth control pills, hormone replacement therapy - may reduce the effectiveness of the IUD.
Additional Considerations
- Food: Emergency contraceptives can be taken with or without food. However, high-fat meals may delay absorption and reduce effectiveness.
- Alcohol: Alcohol does not directly interact with emergency contraceptives. However, it can dehydrate the body, making side effects such as nausea and vomiting more likely.
