Side Effects of Ativan (Lorazepam)
Common Side Effects: Sedation, Dizziness, and Weakness
Lorazepam, commonly known by its brand name Ativan, is a benzodiazepine frequently prescribed for anxiety, pre-surgical sedation, and as a general sedative. Common side effects include sedation, dizziness, weakness, unsteadiness, and disorientation . These effects can significantly impair daily activities, including driving and operating machinery.
Impact on Driving and Psychomotor Abilities
One of the critical concerns with lorazepam is its impact on driving and psychomotor abilities. A review of drug-impaired driving cases revealed that lorazepam can cause significant impairment, independent of the concentration detected in the blood . This impairment is due to the drug's sedative properties, which can lead to decreased alertness and coordination.
Antiemetic Use and Associated Side Effects
Lorazepam is also used in antiemetic regimens, particularly for managing post-chemotherapy symptoms. In a study comparing lorazepam with prochlorperazine, lorazepam was found to significantly reduce the total post-therapy symptom experience by decreasing fatigue and pain . However, side effects such as sedation and dizziness were noted, which are consistent with its general side effect profile.
Amnesic Effects and Other Adverse Reactions
Lorazepam has been studied for its amnesic effects, particularly in cancer patients undergoing chemotherapy. In these studies, patients often experienced amnesia for the day of chemotherapy, which was considered beneficial in reducing the psychological burden of treatment Laszlo1985Semrad1984. However, adverse reactions such as perceptual disturbances, urinary incontinence, diarrhea, hypotension, and severe transient amnesia were reported .
Minimal Long-term Adverse Effects
Despite these side effects, long-term adverse effects of lorazepam appear to be minimal. In clinical trials, lorazepam was found to be effective and safe, with no evidence of dependence . This makes it a viable option for short-term use in managing anxiety and other conditions.
Conclusion
Lorazepam (Ativan) is a widely used benzodiazepine with a range of applications from anxiety management to antiemetic regimens. While it is effective, it comes with a spectrum of side effects including sedation, dizziness, and significant impairment of psychomotor abilities. These side effects necessitate caution, particularly in activities requiring full alertness such as driving. Despite these concerns, lorazepam remains a valuable medication with minimal long-term adverse effects when used appropriately.
