What Other Drugs Will Affect Xanax?

Thursday, August 20th, 2009

Before using Xanax, tell your doctor if you regularly use other medicines that make you sleepy (such as cold or allergy medicine, narcotic pain medicine, sleeping pills, muscle relaxers, and medicine for seizures, depression, or anxiety). They can add to sleepiness caused by Xanax.

Before taking Xanax, tell your doctor if you are using any of the following drugs:

  • birth control pills;
  • cimetidine (Tagamet);
  • diltiazem (Tiazac, Cartia, Cardizem);
  • isoniazid (IsonaRif, Rifamate);
  • propoxyphene (Darvon, Darvocet);
  • seizure medication;
  • antibiotics such as fluconazole (Diflucan), itraconazole (Sporanox) or ketoconazole (Nizoral); or
  • antidepressants such as fluvoxamine (Luvox), desipramine (Norpramin), or imipramine (Janimine, Tofranil).

If you are using any of these drugs, you may not be able to use Xanax, or you may need dosage adjustments or special tests during treatment.

There may be other drugs not listed that can affect Xanax. Tell your doctor about all the prescription and over-the-counter medications you use. This includes vitamins, minerals, herbal products, and drugs prescribed by other doctors. Do not start using a new medication without telling your doctor.
