Nor-QD Drug Interactions

If substances such as St. John's wort, antibiotics, or barbiturates are taken in combination with Nor-QD, drug interactions could occur. These interactions can make the birth control pill less effective, possibly increasing the risk of pregnancy. It is generally recommended to use a backup method of birth control in case a Nor-QD drug interaction is severe enough to lead to unintentional pregnancy.

An Introduction to Nor-QD Drug Interactions

Nor-QD® (norethindrone) can potentially interact with numerous other medicines. Many of these interactions can be severe enough to lead to unintentional pregnancy, and a backup method of birth control (such as condoms) may be recommended in many cases. Some of the medicines that may lead to Nor-QD drug interactions include:
  • Aminoglutethimide (Cytadren®)
  • Antibiotics
  • Aprepitant (Emend®)
  • Barbiturate medications, such as:
    • Amobarbital (Amytal®)
    • Butalbital (Fioricet®, Fiorinal®)
    • Pentobarbital (Nembutal®)
    • Phenobarbital (Luminal®)
    • Primidone (Mysoline®)
