Tramadol side effects
Get emergency medical help if you have signs of an allergic reaction to tramadol (hives, difficult breathing, swelling in your face or throat) or a severe skin reaction (fever, sore throat, burning in your eyes, skin pain, red or purple skin rash that spreads and causes blistering and peeling).
Tramadol can slow or stop your breathing, and death may occur. A person caring for you should give naloxone and/or seek emergency medical attention if you have slow breathing with long pauses, blue colored lips, or if you are hard to wake up.
Tramadol may cause serious side effects. Call your doctor at once if you have:
noisy breathing, sighing, shallow breathing, breathing that stops during sleep;
a slow heart rate or weak pulse;
a light-headed feeling, like you might pass out;
seizure (convulsions); or
low cortisol levels – nausea, vomiting, loss of appetite, dizziness, worsening tiredness or weakness.
Seek medical attention right away if you have symptoms of serotonin syndrome, such as: agitation, hallucinations, fever, sweating, shivering, fast heart rate, muscle stiffness, twitching, loss of coordination, nausea, vomiting, or diarrhea.
Serious breathing problems may be more likely in older adults and people who are debilitated or have wasting syndrome or chronic breathing disorders.
Common side effects of tramadol may include:
nausea and vomiting;
