Side Effects of Tramadol/Acetaminophen
Dry mouth, drowsiness, insomnia, and diarrhea are some of the most common side effects of tramadol/acetaminophen. Most side effects of the medication are mild and either do not require medical attention or can be treated easily. However, there are certain tramadol/acetaminophen side effects that should be reported to your healthcare provider immediately, including loss of balance, severe constipation, or loss of consciousness.
As with any medicine, tramadol/acetaminophen (Ultracet®) can cause side effects. However, not everyone who takes the medication will experience side effects. Most people tolerate it quite well. If side effects do occur, in most cases, they are minor and either require no treatment or can easily be treated by you or your healthcare provider.
