The administration of Ativan injection is reserved for the intervention of trained personnel in clinical or hospital settings. It may either be given by way of the veins (intravenously) or injected into the muscles (intramuscularly) depending on the state of the patient and the required speed of action.

• Intravenous (IV) Injection: For rapid onset of action, lorazepam can be injected directly into the bloodstream through an IV. this method is done a lot in emergencies where there is a patient suffers seizures or extreme agitation.

• Intramuscular (IM) Injection: Lorazepam can also be injected into the muscle but in most cases the speed at which the drug elicits its effects is not as fast when injected intramuscularly as in intravenous injection.

The dosage and frequency of injection, however, will vary according to the condition of the patient, the intensity of the symptoms, and the type of medical environment.

The medication Ativan (lorazepam) facilitates the effects of a naturally occurring neurotransmitter named gamma-aminobutyric acid (GABA) which diminishes the activity of the brain. It acts on the GAB An receptors in the brain thereby increasing the activity of GABA. This activity in the brain calms the nervous system and helps in overcoming anxiety, inducing sleep, and controlling fits.

• Anxiolytic Effect: Ativan is useful in treating anxiety focusing on the GABAergic mechanism because it increases GABA activity.

• Sedative Effect: It also inhibits the activity of the central nervous system resulting in relaxation and drowsiness.

• Anticonvulsant Effect: The action of lorazepam which decreases the abnormal increase of electrical discharge in the brain also works for managing and controlling seizures.

While Ativan is effective, it can cause a variety of side effects. These can range from mild to severe, and some may be more common when the medication is administered by injection.

• Drowsiness or Sedation
• Dizziness
• Headache
• Fatigue or weakness
• Blurred vision

• Dependence and Tolerance: Ativan, similar to other benzodiazepines, can result in physical dependence and tolerance when used over extended periods. Patients should be carefully assessed for any possible tendencies of abuse or addiction, especially if the medication is to be used for a long time. 

• CNS Depression: Central nervous system (CNS) effects such as Ativan CNS depression can result in changes in coordination, judgment, and reaction times. Until the patient has determined how the drug affects him or her, he or she should not drive a vehicle, operate heavy machinery, or do any similar activity. 

• Elderly Patients: Geriatric patients may be more vulnerable to the effects of Ativan than other age groups and may need to be treated with smaller than standard doses.

Ativan can interact with several due to the nature of how medicines work; this might even heighten its effect or counter it. These include:

• CNS Depressants: Treatment with Ativan has its risks when combined with other CNS depressants such as alcohol, opioids, barbiturates, or other benzodiazepines since this combination tends to produce severe sedation and leaves the patient at high risks of respiratory depression or even an overdose that is fatal.

• Anticonvulsants: Drugs such as phenytoin or carbamazepine can inhibit the action of lorazepam.

• Antifungal and antibiotics: Use of drugs such as ketoconazole or erythromycin can result in increased blood levels of lorazepam thus enhancing its side effects.

The suitable amount of drug Ativan (injection) varies according to the ailment being treated as well as the individual’s reaction to the medicine. Any dosage should be prescribed solely by a medical professional. Here are some general dosage recommendations: 

• Acute anxiety or agitation:

The commonly used dose via the intravenous route is one to two milligrams which should be administered over a span of two minutes. It can be repeated after 6 to 8 hours if needed. 

• Seizure Control (Status Epilepticus):

The usual initial dosage for intravenous route use is slow intravenous bolus of 4mg. If prolonged seizures activity occurs until then further doses may be given at medical supervision’s judgment. 

• Preoperative Sedation:

IV or IM administration of Ativan 1-2 mg may be possible approximately 30 minutes prior to the procedure.

Don’t use  large amount Ativan  that can  cause lead to extreme lethargy, disorientation, difficulty in breathing, and fainting spells. The risk of overdose is high especially where Ativan is taken alongside other drugs such as alcohol or opioids that also depress the central nervous systems.

• Overdose Management. In the event that you suspect an overdose, please contact emergency services without delay. Most cases of overdose would require supportive management such as airway control and in rare cases the use of flumazenil, a drug used to counteract the effects of lorazepam, hyperanxiolytics, and other sedatives.
