What Causes Seizures After Taking Tramadol?

default
Posted on Mon, 21 Dec 2015
Question: My 25yr old daughter had A GA for a Laparoscopy(Healthy young women on no regular medication) In Recovery unit she was given Tramadol IV for pain and soon after the Tramadol was administered she starting having major seizures which continued for 3 days.CT scan and blood results were all normal.Epilepsy was ruled out. She was treated with regular doses of IV Midazolam and Lorazepam. She was also given IM Valium x1 and IM Baclofen x1. On Day 3 she was seen by a Neurologist and all medications were discontinued. By this stage she was drugged to the hilt and couldn't walk unaided. Day 5 she was discharged home a very traumatised girl still requiring assistance to walk. We were given no specific cause for this serious reaction. Suggestion was that it was a combination of The GA drugs and Tramadol.
Understandably my daughter is very fearful of having a GA in the future.
Can you please give your opinion on this case.

Brief Answer:
Tramadol by itself is a potential seizure trigger

Detailed Answer:
Tramadol is typically disliked by most neurologists precisely for its property of lowering seizure thresholds in people who are susceptible or already suffer with epileptic disorders.

Without knowing what the general anesthetic I think it is difficult to say anything about reactions between that agent and the tramadol. General anesthetic agents aren't really considered as epileptogenic since they are in fact some of the most POWERFUL anticonvulsants we have. That's what we turn to in order to calm someone down with status epilepticus who responds to no other measure.

I don't blame your daughter for having trepidations about going under again. I would also check for the following relatively common problem found in people undergoing general anesthesia procedures....check her for what's called SUCCINYLCHOLINESTERASE DEFICIENCY or possibly PSEUDOCHOLINESTERASE deficiency. These are congenital abnormalities found in about 3-5% of patients undergoing general anesthesia procedures and represents a congenital problem that can predispose them for problems with anesthetics. I would be surprised if she would not have had these tests done prior to surgery since they are typically STANDARD screening bloods that are done on everybody just because of the potential complications.

I would definitely X out TRAMADOL in the future from any medication regimen.

If the neurologist clearly ruled out epilepsy as a complicating comorbidity (and it sounds reasonable that it should be ruled out) then, drug reaction is the next likely cause. However, just be aware that people going through something like this SOMETIMES can unmask an underlying seizure or epileptic condition. If I were in your daughter's position I would definitely make sure that an extensive and thorough workup was completed to rule out an underlying disorder and then, I would take the proper precautions to be sure that no underlying condition was unmasked. This means I would not get back to driving a car, handling dangerous equipment, or go climbing up to heights on ladders, etc. I would not travel to remote or isolated places alone or without a person accompanying and I would maintain a diary of "funny feelings" that came upon me for the next 6 months and stay in touch with the neurologist.

If everything checks out after 6 months then, I would be much more comfortable stating that NO EPILEPTIC CONDITION actually existed and chalk this up to complications of medications (probably Tramadol or reaction of other medications with Tramadol).

I hope this addresses your concerns and that you will keep me in mind for future queries and questions regarding these or other neurological/medical issues that I may be able to help resolve.

Write to me at: XXXX for additional comments, concerns, or to provide status updates if this possible. I would appreciate your rating of this interaction on a HIGH STAR SCALE if you find it helpful or informative related to your daughter's condition and would very much appreciate a few words related to feedback that you'd like to express in whatever light you wish to express yourself.
