Xanax and Zanaflex

In the database of official manuals used in the service creation an interaction registered by statistical results of studies was found, which can either lead to negative consequences for the patient health or strengthen a mutual positive effect. A doctor should be consulted to address the issue of joint drug administration.

Using tiZANidine together with ALPRAZolam may increase side effects such as dizziness, drowsiness, confusion, and difficulty concentrating. Some people, especially the elderly, may also experience impairment in thinking, judgment, and motor coordination. You should avoid or limit the use of alcohol during treatment. In addition, these medications may also have additive effects in lowering your blood pressure. You may experience headache, dizziness, lightheadedness, fainting, and/or changes in pulse or heart rate. These side effects are most likely to be seen at the beginning of treatment, following a dose increase, or when treatment is restarted after an interruption. Let your doctor know if you develop these symptoms and they do not go away after a few days or they become troublesome. Avoid driving or operating hazardous machinery until you know how the medications affect you, and use caution when getting up from a sitting or lying position. It is important to tell your doctor about all other medications you use, including vitamins and herbs. Do not stop using any medications without first talking to your doctor.

MONITOR: The sedative effect of tizanidine may be potentiated by concomitant use of other agents with central nervous system (CNS) depressant effects. In addition, tizanidine and many of these agents (e.g., alcohol, anxiolytics, sedatives, hypnotics, antidepressants, antipsychotics, opioids, muscle relaxants) also can exhibit hypotensive effects, which may be additive during coadministration and may increase the risk of symptomatic hypotension and orthostasis, particularly during initiation of therapy or dose escalation. Tizanidine itself is a central alpha-2 adrenergic agonist. Pharmacologic studies have found tizanidine to possess between 1/10 to 1/50 of the potency of clonidine, a structurally similar agent, in lowering blood pressure. In a single-dose study where blood pressure was monitored closely after dosing, two-thirds of patients treated with an 8 mg dose had a 20% reduction in either the diastolic or systolic blood pressure. The reduction was seen within 1 hour after dosing, peaked 2 to 3 hours after dosing, and was associated at times with bradycardia, orthostatic hypotension, lightheadedness, dizziness, and rarely, syncope. The hypotensive effect of tizanidine is dose-related and has been measured following single doses of 2 mg or more.

MANAGEMENT: Caution is advised and more gradual dose titration may be appropriate when tizanidine is used with other substances that can cause CNS depression and/or hypotension, particularly in elderly or debilitated patients. Ambulatory patients should be counseled to avoid hazardous activities requiring complete mental alertness and motor coordination until they know how these agents affect them, and to avoid rising abruptly from a sitting or recumbent position. Patients should contact their physician if they experience dizziness, lightheadedness, syncope, orthostasis, or excessive CNS effects that interfere with their normal activities.
