Those diagnosed with epilepsy or certain other neurological conditions are more vulnerable to seizures if the threshold is reduced, and should be compliant with their anticonvulsant drug regimen. Medications that lower seizure threshold include the antidepressant and nicotinic antagonist bupropion, the atypical opioid analgesics tramadol and ...
Tramadol also acts as an opioid agonist and thus can increase the risk for side effects when used with other opioid and opioid-containing analgesics (such as morphine, pethidine, tapentadol, oxycodone, fentanyl, and Tylenol 3). [61] Tramadol increases the risk for seizures by lowering the seizure threshold.

Patients whose epilepsy is uncontrolled by their medication (i.e., it is refractory to treatment) are selected to see if supplementing the medication with the new drug leads to an improvement in seizure control. Any reduction in the frequency of seizures is compared against a placebo. [21]
A higher safety-based therapeutic index is preferable instead of a lower one; an individual would have to take a much higher dose of a drug to reach the lethal threshold than the dose taken to induce the therapeutic effect of the drug. However, a lower efficacy-based therapeutic index is preferable instead of a higher one; an individual would ...
Some patients request to be switched to a different narcotic due to stigma associated with a particular drug (e.g. a patient refusing methadone due to its association with opioid addiction treatment). [4] Equianalgesic charts are also used when calculating an equivalent dosage of the same drug, but with a different route of administration.
Antipsychotics are not recommended for benzodiazepine withdrawal (or other CNS depressant withdrawal states) especially clozapine, olanzapine or low potency phenothiazines, e.g., chlorpromazine as they lower the seizure threshold and can worsen withdrawal effects; if used extreme caution is required. [148]
Seizures induced by chemicals like flurothyl were clinically effective as electric convulsions with lesser side effects on memory retention. Therefore, considering flurothyl induced seizures in modern anesthesia facilities is encouraged to relieve medication treatment resistant patients with psychiatric illnesses like mood disorders and catatonia.
