What is the shelf life for Ativan?

Ativan (lorazepam) is a benzodiazepine medication used to treat anxiety, insomnia, and other conditions. Like most medications, Ativan has a limited shelf life and potency over time. Understanding Ativan’s shelf life and proper storage can help ensure patients get the full benefits when taking this medication as prescribed.

What is the shelf life of Ativan?

The shelf life of Ativan depends on the form of the medication:

Ativan tablets

– Unopened bottles: Ativan tablets remain potent for 4 years from the manufacturing date if stored properly. The expiration date is printed on the manufacturer’s bottle.

– Opened bottles: Ativan tablets will remain effective for up to 6 months after opening, as long as they are stored correctly.

Ativan injection

– Unopened vials: Ativan injectable solution is good for 4 years from the manufacturing date if unopened and stored properly. The expiration date is printed on the vial.

– Opened vials: Ativan injections retain full potency for up to 24 hours at room temperature or up to 7 days if refrigerated once opened. Discard any unused portion after this time.

Does expired Ativan lose potency?

Yes, Ativan does begin losing potency after its expiration date. However, expired Ativan may still retain some effectiveness for a short time after the expiration date.

One study found that Ativan tablets stored 3-5 years after expiration retained around 90% potency if kept in the manufacturer’s container. However, Ativan degraded much faster once removed from the original packaging.

While expired Ativan tablets may retain some potency, injectable Ativan degrades much more quickly and should not be used past the opened vial expiration date.

Can you safely take expired Ativan?

It is not recommended to take Ativan past its expiration date. While degraded Ativan may still retain some potency, its effectiveness and dosage strength becomes less predictable the longer it is stored past its expiration date.

Taking expired Ativan could potentially lead to the following issues:

– Reduced effectiveness due to degraded active ingredients
– Difficulty achieving desired therapeutic effect
– Increased risk of side effects if degraded product produces breakdown compounds
– Dosage may be higher/lower than expected

For these reasons, patients should discard expired Ativan properly and obtain a new prescription from their doctor. Never use Ativan past its expiration date without first consulting your healthcare provider.

How should you store Ativan to maximize shelf life?

Proper storage is important for preserving Ativan’s potency and shelf life. Recommended storage conditions include:

Ativan tablets

– Store at controlled room temperature between 68-77°F (20-25°C).
– Keep bottle tightly closed to protect from light and moisture.
– Avoid exposing to excessive heat or humidity.

Ativan injection

– Store vials at controlled room temperature between 68-77°F (20-25°C).
– Keep in original packaging until ready to use.
– Do not freeze solution.

Ativan stored under ideal conditions in its original container should retain full potency for the duration of its 4-year shelf life.

Deviating from the recommended storage conditions can accelerate degradation and shorten its usable life. Carefully follow storage instructions and always check expiration dates before use.

Does Ativan need to be refrigerated?

Refrigeration is generally not required for routine storage of Ativan tablets or injectable vials:

– **Ativan tablets:** Do NOT refrigerate or freeze tablets. Simply store tablets in their original bottle at controlled room temperature between 68-77°F (20-25°C).

– **Ativan injectable:** Refrigeration is optional for prolonging an opened vial’s 24-hour shelf life up to 7 days. However, unopened vials can be stored at controlled room temperature (not refrigerated). Avoid freezing.

The only exception is Ativan liquid concentrate for dilution – this must be refrigerated until use to maintain its shelf life. Diluted Ativan intravenous solutions can be stored either refrigerated or at room temperature.

Always refer to the specific Ativan formulation and package instructions for proper storage conditions. Refrigeration offers limited benefit for routine storage, but can help extend an opened vial.

What are the signs of expired Ativan?

Expired Ativan may show some of the following signs indicating it is past its usable shelf life:

Ativan tablets

– Tablets are discolored or browned
– Chip, break, or crumble easily
– Powdery appearance
– Musty odor
– Bitter taste if medication tastes different

Ativan injectable

– Cloudiness in clear solution
– Discoloration from clear to yellowish or brown
– Particulate matter in solution
– Separation of liquid layers

If Ativan shows any odd textures, colors, smells or tastes, it may be expired and should not be used. When in doubt, check the expiration date on the medication packaging. Discard expired Ativan properly.

Is it dangerous to use expired Ativan?

While not directly dangerous in the short-term, using expired Ativan does come with increased risks:

– **Reduced effectiveness:** Outdated Ativan may have less of its active drug, which could render it ineffective for treating anxiety symptoms.

– **Inaccurate dosing:** The actual drug concentration in expired Ativan is difficult to predict. This could lead to problems from too much or too little medication.

– **Side effects:** Degraded Ativan can produce breakdown products that cause unexpected side effects not seen with properly stored Ativan.

– **Medication errors:** Mixing up expired and non-expired Ativan could lead to accidental overdose or underdosing.

– **Antibiotic contamination:** Ativan injections could become contaminated with dangerous bacteria over time if stored improperly after opening.

Overall, it is much safer to properly discard expired Ativan and only take non-expired medication as directed by your doctor. While risks from expired Ativan are generally low, it is not recommended medical practice.

How should you dispose of expired Ativan?

To safely dispose of Ativan and other expired medications:

– Return to a pharmacy or other DEA-authorized collector site. Many pharmacies offer programs where patients can return unused or expired medicines for proper disposal.

– Mix with an unpalatable substance like cat litter or used coffee grounds in a sealable bag or container. This makes it less appealing for unintended use.

– Dispose in household trash after mixing with unpalatable substances and sealing in containers. Make sure to scratch out any personal information on medicine bottles.

– Participate in community pharmaceutical take-back programs that collect and safely dispose of medications.

– Flush tablets, capsules, and liquids down the toilet only if take-back options are unavailable. Avoid flushing vials or syringes.

Never simply throw loose tablets or vials in the trash or recycle expired medications, as this causes environmental contamination risks. Use caution and seal medications before disposal.

Conclusion

Ativan has an effective shelf life of 4 years from its manufacturing date if stored properly in its original packaging. While expired Ativan tablets may retain some potency for a short time, injectable forms degrade much more quickly. To ensure you get the full benefits and predictable effects, only take Ativan prior to its marked expiration date. Discard expired Ativan correctly to avoid risks from degraded medication. With proper storage and disposal, Ativan can be used safely and effectively within its shelf life.
