Medications that lower seizure threshold include the antidepressant and nicotinic antagonist bupropion, the atypical opioid analgesics tramadol and tapentadol, reserpine, [1] theophylline, [2] antibiotics (fluoroquinolones, imipenem, penicillins, cephalosporins, metronidazole, isoniazid) and volatile anesthetics. So can other factors, including:
Tramadol increases the risk for seizures by lowering the seizure threshold. Using other medications that lower seizure threshold - such as antipsychotic medications , bupropion (an anti-depressant and smoking cessation drug), and amphetamines - can further increase this risk.
Bradycardia; Hypertension (high blood pressure); Allergic reactions (e.g. dyspnoea (shortness of breath), bronchospasm, wheezing, angioneurotic oedema) Anaphylaxis; Changes in appetite
Some medicinal and recreational drugs can dose-dependently precipitate seizures in withdrawal, especially when withdrawing from high doses and/or chronic use. Examples include drugs that affect GABAergic and/or glutamatergic systems, such as alcohol (see alcohol withdrawal ), [ 19 ] benzodiazepines , barbiturates , and anesthetics , among others.
[67] [78] [79] [80] Some antipsychotic agents may be riskier than others during withdrawal, 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. [81]
Opioid withdrawal is a set of symptoms (a syndrome) arising from the sudden cessation or reduction of opioids where previous usage has been heavy and prolonged. [1] [2] Signs and symptoms of withdrawal can include drug craving, anxiety, restless legs syndrome, nausea, vomiting, diarrhea, sweating, and an elevated heart rate. Opioid use triggers ...
Although anxiety can temporarily increase as a withdrawal symptom, there is evidence that a reduction or withdrawal from benzodiazepines can lead to a reduction of anxiety symptoms in the long run. [ 4 ] [ 5 ] Due to these increasing physical and mental symptoms from long-term use of benzodiazepines, slow withdrawal is recommended for long-term ...
Individuals who have had more withdrawal episodes are at an increased risk of very severe withdrawal symptoms, up to and including seizures and death. Long-term activation of the GABA receptor by sedative–hypnotic drugs causes chronic GABA receptor downregulation as well as glutamate overactivity, which can lead to drug and neurotransmitter ...
