Side Effects

Common side effects may include:

• Nausea or stomach upset • Headache • Dizziness or lightheadedness • Fatigue or tiredness • Mild rash or itching

Serious side effects (seek immediate medical attention):

• Severe allergic reactions (rash, hives, swelling, difficulty breathing) • Unusual bleeding or bruising • Severe stomach pain • Signs of liver problems (yellowing of skin/eyes, dark urine) • Chest pain or irregular heartbeat • Severe dizziness or fainting • Signs of serious adverse effects

Drug Interactions

Lorazepam is metabolized by glucuronidation rather than CYP450 enzymes, which means it has fewer pharmacokinetic interactions than many other benzodiazepines. The most important interactions are pharmacodynamic.

Opioids (e.g., oxycodone, hydrocodone, morphine, fentanyl, tramadol): Profound sedation, respiratory depression, coma, and death. An FDA Boxed Warning applies. Avoid co-prescription when possible; if combined, use the lowest effective doses for the shortest duration with close monitoring.
Other CNS depressants (alcohol, sedating antihistamines, gabapentinoids, muscle relaxants, sleep aids): Additive sedation, impaired psychomotor performance, falls, and respiratory depression. Counsel against alcohol and recreational sedatives.
Clozapine: Rare reports of severe respiratory depression, hypotension, and cardiorespiratory arrest when combined with parenteral lorazepam. Avoid IV/IM lorazepam in patients on clozapine.
Probenecid and valproate: Inhibit lorazepam glucuronidation, increasing lorazepam levels and prolonging effects. Reduce lorazepam dose by approximately 50 percent.
Theophylline and aminophylline: May antagonize the sedative effects of lorazepam, potentially reducing efficacy for sedation or anxiety.

Frequently Asked Questions

Oral lorazepam is absorbed within 20 to 30 minutes, with peak effect in about 2 hours. Sublingual and IM routes work somewhat faster, and IV produces effects within minutes. Duration of clinical effect is typically 6 to 8 hours, which is why anxiety dosing is usually divided across the day.

Yes. Physical dependence can develop within 2 to 4 weeks of regular daily use, even at therapeutic doses, and tolerance to anti-anxiety effects often develops over months. Stopping abruptly after prolonged use can trigger withdrawal symptoms — anxiety, insomnia, tremor, and rarely seizures. Any taper should be gradual and physician-supervised.

The American Geriatrics Society Beers Criteria flag benzodiazepines as potentially inappropriate in adults 65 and older because of substantially increased risks of falls, hip fracture, motor vehicle accidents, cognitive impairment, and delirium. Older patients clear lorazepam more slowly, magnifying side effects. Non-benzodiazepine options should be considered first.

No. Combining alcohol with lorazepam significantly amplifies sedation, impairs coordination and judgment, and can dangerously suppress breathing. Even small amounts of alcohol can produce a much larger effect than expected. Avoid alcohol entirely while on this medication.

If you remember within an hour or two of the missed dose, take it as soon as possible. If it is close to the next scheduled dose, skip the missed one and resume your regular schedule — do not double up. If you have been taking lorazepam regularly and miss multiple doses, contact your prescriber to discuss safe restart and any withdrawal-mitigation steps.
