Lorazepam Dosage Guide

### Recognizing Benzodiazepine Overdose **Lorazepam alone:** Deep sedation or unconsciousness, slurred speech, severe ataxia, confusion, respiratory depression (usually mild to moderate). Vital signs may show low blood pressure and decreased respiratory rate. **Combined with depressants (alcohol, opioids, etc.):** All of the above plus severe respiratory depression, cyanosis (blue lips and fingertips), unresponsiveness, respiratory arrest, coma, and death. ### What to Do 1. **Call emergency services immediately** if someone is unresponsive or breathing abnormally after taking lorazepam, especially if they may have combined it with other depressants. 2. **Place them in the recovery position** (on their side) to prevent aspiration if they vomit. 3. **Monitor breathing.** If breathing stops, begin rescue breathing or CPR if trained. 4. **If opioid co-ingestion is suspected**, administer naloxone (Narcan) if available. Naloxone will not reverse benzodiazepine effects, but it will reverse the opioid component, which is often the more immediately lethal element in poly-drug overdoses. ### Hospital Treatment - **Flumazenil** (Romazicon) is a benzodiazepine antagonist that can reverse benzodiazepine sedation. However, its use is controversial in emergency settings because it can precipitate seizures in benzodiazepine-dependent individuals. It is generally reserved for cases of isolated benzodiazepine overdose in non-dependent patients. - **Supportive care:** Airway management, IV fluids, monitoring of respiratory and cardiac function. ### Key Point The lethality of lorazepam is almost entirely context-dependent. Alone, it is difficult to die from. Combined with other depressants, it is one of the most common contributors to drug-related death. The combination risk cannot be overstated.
