Ativan lorazepam is not recommended for use in patients with a primary depressive disorder or psychosis. Use of benzodiazepines, including lorazepam, both used alone and in combination with other CNS depressants, may lead to potentially fatal respiratory depression. Use of benzodiazepines, including lorazepam, may lead to physical and psychological dependence.
As with all patients on CNS-depressant drugs, patients receiving lorazepam should be warned not to operate dangerous machinery or motor vehicles and that their tolerance for alcohol and other CNS depressants will be diminished.
Physical And Psychological Dependence The use of benzodiazepines, including lorazepam, may lead to physical and psychological dependence. The risk of dependence increases with higher doses and longer term use and is further increased in patients with a history of alcoholism or drug abuse or in patients with significant personality disorders.
The dependence potential is reduced when lorazepam is used at the appropriate dose for short-term treatment. Addiction- prone individuals such as drug addicts or alcoholics should be under careful surveillance when receiving lorazepam or other psychotropic agents.
In general, benzodiazepines should be prescribed for short periods only e. Extension of the treatment period should not take place without reevaluation of the need for continued therapy.
Continuous long-term use of product is not recommended. Abrupt discontinuation of product should be avoided and a gradual dosage-tapering schedule followed after extended therapy. Abrupt termination of treatment may be accompanied by withdrawal symptoms. There is evidence that tolerance develops to the sedative effects of benzodiazepines.
Lorazepam should be used with caution in patients with compromised respiratory function e. COPD , sleep apnea syndrome. Elderly or debilitated patients may be more susceptible to the sedative effects of lorazepam. Therefore, these patients should be monitored frequently and have their dosage adjusted carefully according to patient response; the initial dosage should not exceed 2 mg.
Paradoxical reactions have been occasionally reported during benzodiazepine use. Such reactions may be more likely to occur in children and the elderly. Should these occur, use of the drug should be discontinued. The usual precautions for treating patients with impaired renal or hepatic function should be observed. Dosage for patients with severe hepatic insufficiency should be adjusted carefully according to patient response; lower doses may be sufficient in such patients.
In patients where gastrointestinal or cardiovascular disorders coexist with anxiety, it should be noted that lorazepam has not been shown to be of significant benefit in treating the gastrointestinal or cardiovascular component.
The no-effect dose was 1. The effect was reversible only when the treatment was withdrawn within two months of first observation of the phenomenon. The clinical significance of this is unknown. However, use of lorazepam for prolonged periods and in geriatric patients requires caution, and there should be frequent monitoring for symptoms of upper G.
Safety and effectiveness of Ativan lorazepam in children of less than 12 years have not been established. The majority of people selling prescription drugs illegally are doing so to make a profit so the drug could be marked up considerably.
There are also a number of illegal online drug sites that will try to lure you in with discounted prices. Law enforcement agencies also use price tracking websites to help them understand and monitor where the most drugs are being bought and sold. In any case, the purchasing lorazepam on the street is illegal and anyone doing so can be prosecuted.
Avoiding Purchasing Counterfeit Lorazepam Consumers have many choices when it comes to where they purchase prescription drugs. As you search for convenience and cost, pay close attention to the source of the drug.
You could be wasting money on pills that are ineffective, or worse, you could be risking your health by taking drugs that have been cut with other substances that could be potentially harmful to you. To avoid the risks associated with counterfeit drugs, it is best to buy your drugs directly from a pharmacist. An example would be the inappropriate use to relieve anxiety associated with acute severe asthma.
The anxiolytic effects may also be detrimental to a patient's willingness and ability to fight for breath. However, if mechanical ventilation becomes necessary, lorazepam may be used to facilitate deep sedation. Acute intoxication — Lorazepam may interact synergistically with the effects of alcohol, narcotics, or other psychoactive substances. It should, therefore, not be administered to a drunk or intoxicated person.
Ataxia — This is a neurological clinical sign, consisting of unsteady and clumsy motion of the limbs and torso, due to the failure of gross muscle movement coordination, most evident on standing and walking. It is the classic way in which acute alcohol intoxication may affect a person. Benzodiazepines should not be administered to already-ataxic patients.
Acute narrow-angle glaucoma — Lorazepam has pupil-dilating effects, which may further interfere with the drainage of aqueous humor from the anterior chamber of the eye, thus worsening narrow-angle glaucoma. Sleep apnea — Sleep apnea may be worsened by lorazepam's central nervous system depressant effects. It may further reduce the patient's ability to protect his or her airway during sleep. Pregnancy and breast feeding — Lorazepam belongs to the Food and Drug Administration FDA pregnancy category D, which means it is likely to cause harm to the developing baby if taken during the first trimester of pregnancy.
The evidence is inconclusive whether lorazepam if taken early in pregnancy results in reduced intelligence, neurodevelopmental problems, physical malformations in cardiac or facial structure, or other malformations in some newborns. Lorazepam given to pregnant women antenatally may cause floppy infant syndrome [55] in the neonate, or respiratory depression necessitating ventilation.
Regular lorazepam use during late pregnancy the third trimester , carries a definite risk of benzodiazepine withdrawal syndrome in the neonate. Neonatal benzodiazepine withdrawal may include hypotonia , reluctance to suck, apneic spells, cyanosis , and impaired metabolic responses to cold stress. Symptoms of floppy infant syndrome and the neonatal benzodiazepine withdrawal syndrome have been reported to persist from hours to months after birth.
Lorazepam is present in breast milk, so caution must be exercised about breastfeeding. Specific groups[ edit ] Children and the elderly — The safety and effectiveness of lorazepam is not well determined in children under 18 years of age, but it is used to treat acute seizures.
Dose requirements have to be individualized, especially in the elderly and debilitated patients in whom the risk of oversedation is greater. Long-term therapy may lead to cognitive deficits, especially in the elderly, which may only be partially reversible.
The elderly metabolize benzodiazepines more slowly than younger people and are more sensitive to the adverse effects of benzodiazepines compared to younger individuals even at similar plasma levels. Additionally, the elderly tend to take more drugs which may interact or enhance the effects of benzodiazepines. Benzodiazepines, including lorazepam, have been found to increase the risk of falls and fractures in the elderly. As a result, dosage recommendations for the elderly are about half of those used in younger individuals and used for no longer than two weeks.
Falls and hip fractures are frequently reported. The combination with alcohol increases these impairments. Partial, but incomplete, tolerance develops to these impairments.
Like oxazepam , it does not require hepatic oxidation, but only hepatic glucuronidation into lorazepam-glucuronide. Therefore, impaired liver function is unlikely to result in lorazepam accumulation to an extent causing adverse reactions. Staff must use chaperones to guard against allegations of abuse during treatment. Such allegations may arise because of incomplete amnesia, disinhibition, and impaired ability to process cues.
Because of its relative long duration of residual effects sedation , ataxia , hypotension , and amnesia , lorazepam premedication is best suited for hospital inpatient use. Patients should not be discharged from the hospital within 24 hours of receiving lorazepam premedication unless accompanied by a caregiver.
They should also not drive, operate machinery, or use alcohol within this period. Drug and alcohol dependence — The risk of abuse of lorazepam is increased in dependent patients. Higher doses and longer periods of use increase the risk of developing a benzodiazepine dependence.
Potent benzodiazepines, such as lorazepam, alprazolam , and triazolam , have the highest risk of causing a dependence. This is desirable with amnesic and sedative effects but undesirable with anxiolytic, hypnotic, and anticonvulsant effects. Patients initially experience drastic relief from anxiety and sleeplessness, but symptoms gradually return, relatively soon in the case of insomnia, but more slowly in the case of anxiety symptoms.
After four to six months of regular benzodiazepine use, evidence of continued efficacy declines. If regular treatment is continued for longer than four to six months, dose increases may be necessary to maintain effects, but treatment-resistant symptoms may in fact be benzodiazepine withdrawal symptoms.
Increasing the dose may overcome tolerance, but tolerance may then develop to the higher dose and adverse effects may persist and worsen. The mechanism of tolerance to benzodiazepines is complex and involves GABAA receptor downregulation, alterations to subunit configuration of GABAA receptors, uncoupling and internalisation of the benzodiazepine binding site from the GABAA receptor complex as well as changes in gene expression.
Lorazepam's relatively short serum half-life, its confinement mainly to the vascular space, and its inactive metabolite can result in interdose withdrawal phenomena and next-dose cravings, that may reinforce psychological dependence. Because of its high potency, the smallest lorazepam tablet strength of 0.
