Head-to-head comparisons of medication uses, side effects, warnings, and more.
Key takeaways
Tizanidine (Zanaflex) and tramadol are both medications that can help with muscle-related issues, but they work in different ways and are used for different conditions. Tizanidine is an alpha-2 adrenergic receptor agonist used to treat muscle stiffness and rigidity, often related to conditions like multiple sclerosis. It is taken orally, usually three times a day, and is available in both brand and generic forms. Common side effects include dry mouth, sleepiness, and dizziness. Tramadol, on the other hand, is an opioid used to manage pain that isn't relieved by non-opioid medications. It is a controlled substance and comes in immediate-release and extended-release forms. Tramadol can cause side effects like constipation, nausea, and dizziness, and can lead to addiction and misuse. Tramadol can interact with many medications. Both medications can cause withdrawal symptoms if stopped suddenly. Tizanidine can cause low blood pressure, while tramadol can increase the risk for dangerously slow breathing. The risk for these serious side effects is higher if taken with interacting medications.

Summary for Opioid
Prescription only
Tramadol is an opioid pain medication used when non-opioid medications aren't working well enough to control pain. Compared to other opioids, tramadol might have a lower risk of misuse and dependency. But tramadol is a controlled substance and has a lot of potentially serious risks, so it must be used with caution.
