Quick Facts Scannable
- Both Ativan and Clonazepam are benzodiazepines used primarily to treat anxiety disorders.
- They work by enhancing the effects of a neurotransmitter called GABA in the brain.
- Common forms include tablets and, for Ativan, also injections for acute settings.
- They start working relatively quickly, often within 1 hour orally.
- Common side effects include drowsiness, dizziness, and fatigue.
- Significant interactions can occur with alcohol and other CNS depressants.
- Special precautions needed for pregnant or breastfeeding women, and those with liver or kidney conditions.
- Seek urgent medical help for severe allergic reactions or overdose.
What It Is and How It Works
Benzodiazepines such as Ativan and Clonazepam work by binding to the gamma-aminobutyric acid (GABA) receptor sites in the brain. This binding enhances the neurotransmitter\’s inhibitory effects, resulting in a calming effect on the nervous system. These medications can effectively reduce the symptoms of severe anxiety, panic attacks, and certain seizure disorders.
Indications / Uses
Ativan is commonly prescribed for anxiety relief, sedation before medical procedures, and treatment of acute seizure disturbances. Clonazepam, on the other hand, is often used for seizure disorders like epilepsy and panic disorders. While both drugs share similar properties, their use may vary based on specific patient needs and medical conditions.
Dosage Forms and Typical Dosing Considerations
Ativan is available in tablet form and can be administered via injection in acute care settings, while Clonazepam is primarily available as tablets and dissolving wafers. Dosing is highly individualized based on factors such as age, weight, specific medical condition, kidney/liver function, and concurrent use of other medications. Always adhere to the prescribed dosing schedule provided by a healthcare professional.
How to Take It Correctly Step-by-Step
When taking Ativan or Clonazepam, follow these general guidelines:
- Take at the same time each day as directed by your healthcare provider.
- Do not mix with alcohol as it can increase sedation and side effects.
- Do not abruptly stop the medication without consulting your doctor, as this can cause withdrawal symptoms.
- If you miss a dose, take it as soon as you remember unless it is close to the time of your next dose. Do not double doses.
- Store the medication at room temperature away from moisture and heat.
Side Effects Common to Serious
Common Side Effects
Common side effects may include drowsiness, dizziness, tiredness, blurred vision, and coordination problems. These effects can diminish as your body adjusts to the medication.
Less Common Side Effects
Less common effects include headaches, gastrointestinal disturbances, and changes in appetite.
Serious or Rare Side Effects
Serious reactions can include significant mood changes, confusion, hallucinations, and difficulty breathing. Seek immediate medical help if these occur. An allergic reaction, though rare, may present as rash, itching/swelling (especially of the face/tongue/throat), severe dizziness, or trouble breathing, which requires urgent medical attention.
Contraindications & Precautions
Ativan and Clonazepam should be used with caution or might be contraindicated in individuals with:
- Allergies to benzodiazepines
- Severe respiratory problems
- History of substance use disorder
- Pregnancy or breastfeeding (only when the benefits outweigh the risks)
- Liver disease, as dose adjustments may be necessary
- Elderly populations due to increased risk of sedation and falls
Use in pediatric settings requires careful evaluation and monitoring.
Drug, Food, and Supplement Interactions
Benzodiazepines can interact with other CNS depressants, antihistamines, anticonvulsants, antipsychotics, and certain antidepressants, leading to enhanced sedative effects. Additionally, grapefruit and some nutritional supplements might influence drug metabolism. Always inform your healthcare provider about all medications and supplements you are taking.
