There is less evidence supporting the risk of serious breathing difficulties with gabapentinoids alone in otherwise healthy individuals, and we will continue to monitor this population for additional evidence. Do not take more of the medicine or take it more often than prescribed because doing so can cause serious problems or death. Always tell all your health care professionals about all the medicines you are taking, including prescription and over-the-counter OTC medicines.
It is helpful to keep a list of all your current medicines in your wallet or another location where it is easily retrieved. You can fill out and print a copy of My Medicine Record. Read the patient Medication Guide every time you receive a prescription for a gabapentinoid.
The Medication Guide will be updated with new or other important information about your medicine. The Medication Guide explains the important things that you need to know.
These include the side effects, what the medicine is used for, interactions with other medicines, how to take and store it properly, and other things to watch out for when you are taking the medicine. Talk to your health care professional if you have any questions or concerns.
To help FDA track safety issues with medicines, report side effects from gabapentin, pregabalin, or other medicines to the FDA MedWatch program, using the information in the "Contact FDA" box at the bottom of this page. Additional Information for Health Care Professionals.
FDA is warning that serious, life-threatening, and fatal respiratory depression has been reported with the gabapentinoids, gabapentin Neurontin, Gralise, Horizant and pregabalin Lyrica, Lyrica CR. Most cases occurred in association with co-administered central nervous system CNS depressants, especially opioids, in the setting of underlying respiratory impairment, or in the elderly.
Our evaluation of respiratory depression with the gabapentinoids provides some evidence contrary to the widely held belief that gabapentinoids lack drug interactions and have wide therapeutic indices. Published studies demonstrate these drugs can behave in an additive way to potentiate central nervous system CNS and respiratory depression.
When co-prescribing gabapentinoids with another CNS depressant, particularly an opioid, or in patients with underlying respiratory impairment, initiate the gabapentinoid at the lowest dose. Adjust the dose of both gabapentin and pregabalin in patients with renal impairment and patients undergoing hemodialysis, because both drugs are excreted by the kidneys.
Monitor for symptoms of respiratory depression and sedation, especially when co-prescribing gabapentinoids with an opioid or other CNS depressant such as a benzodiazepine or when prescribing to patients with underlying respiratory impairment, or elderly patients.
The management of respiratory depression may include close observation, supportive measures, and reduction or withdrawal of CNS depressants, including the gabapentinoid. Gabapentinoids used for analgesia or seizure control should be tapered prior to discontinuation. See the prescribing information for specific tapering guidance. Encourage patients to read the Medication Guide they receive with each gabapentinoid prescription, which explains the safety risks and provides other important information.

All paper forms will be stored in a locked file cabinet located in the Pain and Palliative Care department office. Data will be entered into Excel on a secure, password-protected Children's server and will be exported to SPSS for analysis. The study coordinator will maintain all paper and electronic data. Risks There is no additional medical risk associated with post-surgical pain management above and beyond the usual risks.
Neither tramadol nor gabapentin pose any known additional safety risk. However, because little has been published in the pediatric literature about these two medications and their application in the postoperative setting, the researchers will form a small Data and Safety Monitoring Committee comprised of Children's staff members who are not part of the study. This committee will be responsible for reviewing serious adverse events as requested by the researchers e.
As with any study, there is a risk of loss of confidentiality due to the possibility that people outside the study e. The researchers will make every effort to ensure patients' privacy through use of private rooms for all research-related activities. Paper research forms will be stored in the Pain and Palliative Care office in a locked file cabinet, and all electronic data will be stored on a password-protected file on the Children's server.
Benefits There is a possibility that children who receive tramadol plus gabapentin with PRN ibuprofen during the recovery period will report better pain control, fewer side effects, or both than the children who receive tramadol plus PRN ibuprofen only.
Future children and their families may benefit from the knowledge gained from the study in terms of improved pain management during the post-tonsillectomy recovery period.
The following outcomes will be measured at two, four and 24 hours post-surgery, and then daily for the duration of the follow-up period:. The PPPM scores and parental global satisfaction with their child's recovery between two groups will be compared using the two-sample t-test or Mann-Whitney test as well.
Eta correlation coefficients will be calculated to examine the relationship between PPPM score and the pain intensity score. The researchers plan to enroll at least 80 parents. The study will take place on Children's Minneapolis campus.
This study will make use of CHC's outpatient pharmacy services in order to ensure proper dispensing and blinding. Other Name: Neurontin Drug: Tramadol Both study arms will receive tramadol per dosing details listed in the study arm descriptions. Efficacy will be measured through daily collection of three pain scores FACES or numeric; rating : "pain right now," "typical pain over the past 24 hours," and "worst pain in the past 24 hours.
All efficacy measures will be recorded in a take-home diary by parents for 10 days postoperatively. Safety will be measured through use of a daily take-home diary that the parents fill out, and through phone calls made to parents by the study coordinator every two days during the day recovery period.
Specifically, parents will document, on a daily basis, number and occurence of any side effects e. Talk with your doctor and family members or friends about deciding to join a study.
