Melatonin is a natural hormone that is produced by the pineal gland in the brain and then released into the bloodstream. Darkness prompts the pineal gland to start producing melatonin while light causes that production to stop. As a result, melatonin helps regulate circadian rhythm and synchronize our sleep-wake cycle with night and day. In doing so, it facilitates a transition to sleep and promotes consistent, quality rest.
Melatonin created within the body is known as endogenous melatonin, but the hormone can also be produced externally. Exogenous melatonin is normally made synthetically in a laboratory and, as a dietary supplement, it is most often sold as a pill, capsule, chewable or liquid.
Melatonin supplements is taken to adjust the body’s internal clock. Melatonin is most commonly used for insomnia and improving sleep in different conditions. For example, it is used for jet lag, for adjusting sleep-wake cycles in people whose daily work schedule changes (shift-work disorder), and for helping people establish a day and night cycle.
How does melatonin work?
Melatonin’s main job in the body is to regulate night and day cycles or sleep-wake cycles. Darkness causes the body to produce more melatonin, which signals the body to prepare for sleep. Light decreases melatonin production and signals the body to prepare for being awake. Some people who have trouble sleeping have low levels of melatonin. It is thought that adding melatonin from supplements might help them sleep.
Does Melatonin Expire?
Yes, Melatonin supplements and Melatonin gummies can expire. An expiration date is a date after which a consumable product such as food or medicine should not be used because it may be spoiled, damaged, or ineffective. Expiration dates are especially important for medications because they offer the only indication about whether the product is still safe to use
In the late 1970s, the United States Food and Drug Administration (FDA) mandated that all prescription and over-the-counter (OTC) medical products contain an expiration date. Expiration dates for medicines are often marked “EXP” and are printed on the label or stamped onto the medicine bottle or box.
Can I take expired Melatonin?
No, expired Melatonin is less effective or risky due to a change in chemical composition or a decrease in strength. The expiration date is the final day that the manufacturer guarantees the full potency and safety of a medication. Drug expiration dates exist on most medication labels, including prescription, over-the-counter (OTC) and dietary (herbal) supplements. U.S. pharmaceutical manufacturers are required by law to place expiration dates on prescription products prior to marketing.
Certain expired medications are at risk of bacterial growth and a sub-potent melatonin can complicate sleep problems. Once the expiration date has passed there is no guarantee that the medicine will be safe and effective. If your Melatonin has expired, do not use it. Even though some controversial studies indicate that some drugs can be used after expiry dates, it is better to err on the side of caution in order not to complicate your health condition or trigger unwanted adverse effects.
An expired Melatonin may still interact with anticoagulants and anti-platelet drugs, herbs and supplements. These types of drugs, herbs and supplements reduce blood clotting. Combining an expired melatonin with these drugs might still increase the risk of bleeding.
What to do with expired Melatonin?
The CDC reports that 50,000 young children end up in emergency rooms each year because they got into medicines while an adult wasn’t looking. Expired medicines are also not just a risk to the person they were prescribed for and can injure children and pets if taken by mistake. For all these reasons, proper disposal of unneeded medicines is essential.
Keep this medication in the container it came in, tightly closed, and out of reach of children. Store it at room temperature and away from excess light, heat and moisture (not in the bathroom).
It is important to keep all medication out of sight and reach of children as many containers (such as weekly pill minders and those for Melatonin, creams, patches, and inhalers) are not child-resistant and young children can open them easily. To protect young children from poisoning, always lock safety caps and immediately place the medication in a safe location – one that is up and away and out of their sight and reach. http://www.upandaway.org
Unneeded medications should be disposed of in special ways to ensure that pets, children, and other people cannot consume them. However, you should not flush this medication down the toilet. Instead, the best way to dispose of your medication is through a medicine take-back program. Talk to your pharmacist or contact your local garbage/recycling department to learn about take-back programs in your community. See the FDA’s Safe Disposal of Medicines website (http://goo.gl/c4Rm4p) for more information if you do not have access to a take-back program.
A place for everything
Proper storage is one way to help make sure your medicines will remain safe and effective up to their expiration date. Be sure to read the label to see if there are specific storage instructions for your medicine. Certain medicines need to be stored in the refrigerator and others cannot be exposed to high temperatures. Improper storage – such as a damp bathroom cabinet – can contribute to decreased effectiveness in medicines that have not reached their posted expiration date. For most medicines, to help ensure the proper shelf life of your medicine, it is better to store medicine in a cool, dry place such as a dresser drawer, storage box, closet shelf, or kitchen cabinet.
When storing medicine in a kitchen cabinet, make sure that it is away from hot appliances and the sink due to changing temperatures and humidity which can affect the medicine. When storing medicine in a high traffic area like a kitchen, care should be taken to prevent access by children at risk of accidental poisoning or others who may be tempted to take for abuse/misuse.
Remember to store medicines properly and don’t use expired medicines, it’s not worth the risk!
