How does Dantrium IV treatment interact with other medication or food?

Tell your doctor if you are taking any of the following medications before you receive Dantrium IV and have surgery: allergy medications; anxiety medications; cold or cough medications; diazepam (e.g. valium); estrogen medications, such as oral contraceptives or hormone replacement therapy; medicine for high blood pressure or heart conditions, including amlodipine, diltiazem, felodipine, nicardipine, nifedipine, nimodipine, nisoldipine, or verapamil; medicine to liver conditions; sedatives; seizure medication; sleeping pills; tranquilizers; and certain vitamins. An injection of Dantrium IV may interact with medications not on this list, so tell your doctor about any herbal or dietary supplements, vitamins, or minerals you take. Also, tell your doctor if you smoke, drink alcohol, or take illegal drugs, as they may also affect the safety and quality of your surgery. Ask your doctor how long you should wait after Dantrium IV treatment until it is safe for you to drive or start taking other medications. Your doctor will tell you to avoid alcohol shortly after Dantrium IV treatment, as it can increase the severity of its side effects. Your doctor may supervise you while eating after receiving Dantrium IV treatment, as choking or coughing have been reported.
