How Does A Lockable Pill Bottle Work?

Sometimes, even adults have trouble opening ordinary prescription bottles, so how does a lockable pill bottle work?

Are you locking your prescription medications at home? Locking up your medication can help deter prescription abuse, misuse, and theft, which can often start in the home. In the U.S., the most common source of poisoning in children under 5 is medications in the house.

There is an easy way to help prevent young children from accidental medicine poisoning, as well as deter older teens who may be looking to experiment with easily accessible prescription drugs.

Learn about locking pill bottles, how they work, and how securing your medications can make your home safer for your family.

What is a Locking Pill Bottle?

A locking pill bottle is a medication storage device that provides an extra layer of protection beyond the traditional childproof cap from the pharmacy.

Medication safekeeping devices can come in different forms, from a medicine lock box that can fit multiple prescriptions at once to locking pill bottles that secure a single medication.

Find out how medication storage devices can be a powerful ally in preventing accidental childhood poisoning.

How Do Locking Pill Bottles Work?

A locking pill bottle or locking pill cap works to secure a single medication. The Safer Lock is a locking pill bottle that uses a combination locking cap to keep powerful prescriptions, such as opioids, secured. The Safer Lock cap features a four-digit combination lock.

How Our Combination Lock Works

RxGuardian’s Safer Lock combination cap and bottle can help secure your prescription medications. You may use the combination cap with the bottle it comes with, or fit it over your existing prescription medication bottle.

Our patented locking pill bottle has a 4-digit combination lock with 10,000 possible combinations. The combination of the cap can be set by patients and caregivers. (For bulk orders for organizations, you can preset and assign lot numbers.)

No need to worry about any keys or access methods except the combo. In case you’re worried you might forget the combination, you can register your combination here for easy reference.

Are Locking Pill Bottles Tamper-Proof?

No pill bottle is completely tamper-proof. The only completely tamper-proof method of securing medications is to lock them securely in a steel safe. The Safer Lock and Safer Lock Box are made from food-grade plastics. Someone on a mission to gain unauthorized access to your medications could get into the bottle through various means; however, a destroyed bottle would definitely be an indication of medicine theft.

Our tamper-evident combination locking solutions help families prevent accidental access to powerful prescription medications. In an organizational setting, such as a long-term care facility, the combination cap can also help protect patients from unauthorized access to medications.

The Safer Lock is also USP 671 certified, which measures moisture resistance, and is also certified by the Consumer Product Safety Commission as senior-friendly and child-resistant. The lock can fit over most common pharmaceutical vials available on the market.

Study Finds Parents Regularly Fail to Secure Medications

According to a study, only 4% of caregivers stored medication in a locked or latched place, with 38% saying that the main obstacle in safely storing medication was the lack of a lock or latch to do so.

If given the opportunity, 92% of the participants reported that they would lock medication up if given the chance. After being given one, over 90% of the caregivers reported using it and were satisfied with the results.

How to Store Multiple Medications Safely

The Safer Lock Box allows for the safe storage of multiple prescriptions. You can store numerous prescriptions, all protected by the same four-digit combination and sturdy, food-grade plastic. You can also feel free to store:

  • OTC medications, including cold medicines and cough syrups
  • Vitamins
  • Supplements
  • Pet medications

The Evolution of Prescription Bottles

In 1970, Congress passed the Poison Prevention Packaging Act in reaction to a history of accidents involving children opening household packaging and ingesting the contents.

This innovation in medication packaging helped decrease the number of accidental childhood medication poisonings. However, the design had its flaws. Older adults have complained about difficulty opening child-resistant packaging due to conditions such as arthritis. At the same time, young children and toddlers continue to demonstrate an uncanny ability to breach childproof caps and access prescription medications.

The first wave of the opioid epidemic took place in the 1990s, and in the three decades since, it has only worsened. Misuse and unauthorized access to prescription painkillers have contributed to opioid use disorder and overdose deaths. This has highlighted the need for more effective and secure packaging for prescription medications to protect patients and their families against diversion and unauthorized access.

Today, locking pill bottles demonstrate the newest innovation in prescription safety and provide a safer, more secure solution for prescription medications.

Storing and locking up medication is one of the most impactful ways to combat accidental home poisoning and medication abuse.

Securing medication safely has never been easier, and with Safer Lock, you can do so easily in your own home. Explore our line of medication safety products.
