What precautions apply to Zolpidem Hemitartrate?
When prescribing Nytmel, clinicians should consider several safety aspects.

Major Interactions (Avoid): - Strong CYP3A4 inhibitors (e.g., ketoconazole, itraconazole) – increased zolpidem exposure. - Opioids or other central nervous system depressants – heightened risk of respiratory depression. - Alcohol: additive sedative effects and impaired cognition.
Moderate Interactions (Monitor Closely): - CYP2C9 substrates (e.g., warfarin) – potential alteration in plasma levels. - Antidepressants that affect serotonin reuptake – may increase risk of serotonin syndrome. - Antihistamines with sedating properties – enhanced drowsiness.
