Tramadol Side effects
Along with its needed effects, a medicine may cause some unwanted effects. Although not all of these side effects may occur, if they do occur they may need medical attention.
The most commonly reported adverse drug reactions are nausea, vomiting, sweating and constipation. Drowsiness is reported, although it is less of an issue than for non-synthetic opioids. Patients prescribed tramadol for general pain relief with or without other agents have reported withdrawal symptoms including uncontrollable nervous tremors, muscle contracture, and ‘thrashing’ in bed (similar to restless leg syndrome) if weaning off the medication happens too quickly. Anxiety, ‘buzzing’, ‘electrical shock’ and other sensations may also be present, similar to those noted in Effexor withdrawal. Anecdotally, tramadol is widely regarded by chronic pain sufferers as being among the most difficult of the pain medications to stop after prolonged administration, as withdrawal from both the serotonergic/noradrenergic and the mu-opioid effects is present. Respiratory depression, a common side-effect of most opioids, is not clinically significant in normal doses. By itself, it can decrease the seizure threshold. When combined with SSRIs, tricyclic antidepressants, or in patients with epilepsy, the seizure threshold is further decreased. Seizures have been reported in humans receiving excessive single oral doses (700 mg) or large intravenous doses (300 mg). However, there have been several rare cases of people having grand-mal seizures at doses as low as 100–400 mg orally

Be sure to mention any of the following: antifungal medications such as ketoconazole (Nizoral); digoxin (Lanoxin); erythromycin (E.E.S., E-Mycin, Erythrocin); monoamine oxidase (MAO) inhibitors, including isocarboxazid (Marplan), phenelzine (Nardil), selegiline (Eldepryl, Emsam, Zelapar), and tranylcypromine (Parnate); medications for anxiety, mental illness, nausea, and pain; medications for seizures, such as carbamazepine (Tegretol); muscle relaxants such as cyclobenzaprine (Flexeril); promethazine (Phenergan); quinidine; rifampin (Rifadin, Rifamate, Rimactane, others); sedatives; sleeping pills; selective serotonin reuptake inhibitors (SSRIs) such as citalopram (Celexa), fluoxetine (Prozac, Sarafem), fluvoxamine (Luvox), paroxetine (Paxil), and sertraline (Zoloft); tranquilizers; tricyclic antidepressants such as amitriptyline (Elavil), amoxapine (Asendin), clomipramine (Anafranil), desipramine (Norpramin), doxepin (Adapin, Sinequan), imipramine (Tofranil), nortriptyline (Aventyl, Pamelor), protriptyline (Vivactil), and trimipramine (Surmontil);and warfarin (Coumadin). Many other medications may also interact with tramadol, so be sure to tell your doctor about all the medications you are taking, even those that do not appear on this list. Your doctor may need to change the doses of your medications or monitor you carefully for side effects.
- tell your doctor what herbal products you are taking, especially St. John’s wort.
