Dosage

Medication will likely be given prior to the administration of desflurane.

Interactions

Drug interactions

While some medications never should be taken at or near the same time, other situations may warrant the need for two or more medications prescribed at the same time, despite the chances that an interaction will likely take place. Under these circumstances, your physician may be inclined to slightly adjust the dose, or they may decide to pursue additional precautions to protect you as a patient.

When on desflurane, it is imperative that you inform your physician if you are already prescribed any of the subsequent medications on the list below. The list below includes medications that would potentially have significant interactions, but this list is not all-inclusive.

It is not usually suggested to use desflurane with one or more of the following medications, however certain instances may require the combination. If your doctor decides to prescribe both medications simultaneously, your physician may choose to adjust the dosage or frequency for when and how often you are taking one or more of the medications.

• St John's wort
• Nitrous oxide
• Hydromorphone
• Cisatracurium

Other interactions

Some medications should never be taken at or near mealtime, due to the potential kinds of food interactions that can take place. The use of tobacco or alcohol (even sparingly) could cause a dangerous interaction for patients taking desflurane. Please be sure to consult with your physician about how medications are impacted by tobacco, alcohol and food.

• Upper airway illness (recent) - likelihood of side effects could be increased

Warnings

Your condition must be monitored carefully after you have received this medication. Regular checkups will give your physician a chance to monitor whether or not this medication is working as it should. Urine or blood tests could be required to watch for undesired side effects. Pulmonary and cardiovascular changes should be monitored especially closely.

When choosing whether or not to take a certain medication, patients must compare the risks that may occur from taking the medication against the benefits it may provide. This is a choice you must make carefully with your physician. For this medication, patients must consider the following warnings:

Malignant hyperthermia could take place after patients are given this medication.

There is a rare chance that hyperkalemia could take place after this medication is received. Inform your physician immediately if you experience difficulty breathing; tingling or numbness in the legs, feet, or hands, vomiting or nausea, heartbeat irregularity or confusion after this medication is given.

Prior to having any medical tests, the physician who is in charge must be aware that you are already taking desflurane. Taking this medication could impact certain test results.

Patients who are heading home within 24 hours of having been given a general anesthetic should not operate heavy machinery, drive, or perform additional activities that could turn out to be dangerous if they are not completely alert for 24 hours after getting a general anesthetic. Certain patients may have to wait longer than 24 hours prior to driving. This is due to the tendency of general anesthetics to cause weakness, tiredness, or drowsiness for certain people after receiving anesthetics. General anesthetics can also trigger issues with general coordination and the ability people have to think straight.

For 24 hours, do not consume alcoholic beverages and do not take other types of CNS depressants (medications that tend to cause the nervous system to slow down, potentially triggering drowsiness) for a 24 hour period after having received this medication or another general anesthetic. Doing these things could negatively impact the anesthetic effects. CNS depressants include muscle relaxants, medicine for barbiturates or seizures, pain drugs or narcotics (prescription), sleeping medication, tranquilizers, sedatives, cold medication, allergy medication, hay fever medication and antihistamines.

Never take additional medications if your doctor has not approved them previously. This also refers to vitamin and herbal supplements, nonprescription medications, and of course prescription drugs.

Allergies

If you have previously had any allergic or atypical reactions to a medication, please inform your physician right away. Also, let them know if you have additional kinds of allergies, including to animals, preservatives, dyes and foods. For medications that are non-prescription, read the informational label that discloses the ingredients cautiously.

Parents should take care when this medication is prescribed to young children, or should request an alternative drug.
