These combinations are considered extremely harmful and should always be avoided. Reactions to these drugs taken in combination are highly unpredictable and have a potential to cause death.
There is considerable risk of physical harm when taking these combinations, they should be avoided where possible.
These combinations are not usually physically harmful, but may produce undesirable effects, such as physical discomfort or overstimulation. Extreme use may cause physical health issues. Synergistic effects may be unpredictable. Care should be taken when choosing to use this combination.
Oxazepam has documented abuse potential as a benzodiazepine, though its slow absorption and onset of action result in relatively lower abuse potential compared to faster-acting benzodiazepines such as temazepam, flunitrazepam, or triazolam. Misuse, defined as taking the drug to achieve a high or continuing use against medical advice, has been documented.
Physical dependence develops with regular use, even at standard dosages and after relatively short-term use. Withdrawal symptoms are similar to those seen with alcohol and barbiturate withdrawal, including abdominal and muscle cramps, seizures, depression, insomnia, sweating, tremors, nausea, vomiting, and potentially hallucinations. Withdrawal should be medically supervised with gradual dose reduction.
Oxazepam is generally less toxic in overdose than other benzodiazepines. Overdose symptoms range from mild to severe CNS depression and can occasionally be fatal. Toxicity is significantly increased with coingestion of other CNS depressants such as alcohol or opioids. The rat oral LD50 exceeds 8000 mg/kg.

Respiratory depression may occur in overdose or when combined with other CNS depressants; at typical doses, significant respiratory effects are uncommon except in patients with pre-existing pulmonary conditions such as COPD or limited pulmonary reserve.
Hypotension may rarely occur during use; cardiovascular toxicity is occasionally observed in overdose situations.
Paradoxical reactions including excitement, confusion, aggression, outbursts of anger, and restlessness may occur as side effects. Hallucinations have been reported primarily as a withdrawal symptom rather than during active use.
Oxazepam itself has anticonvulsant properties as a benzodiazepine. However, seizures are a significant risk during withdrawal, particularly after prolonged use or abrupt discontinuation. Some benzodiazepines may trigger seizures in individuals with epilepsy. Flumazenil administration in long-term users may also precipitate seizures.
Oxazepam was patented in 1962 and received approval for medical use in 1964. The compound became one of the most commonly prescribed benzodiazepines in multiple countries during the late 20th century.…
Available as a regulated prescription pharmaceutical with multiple approved brand name and generic products. Generic formulations including Apo-oxazepam have been marketed since 1979, with brand name products such as Novoxapam also historically available. As a benzodiazepine, it is classified as a controlled substance and should only be obtained through licensed pharmacies with valid prescription.
