According to manufacturer Boiron, its solid homeopathic products like Oscillococcinum have a standard 5-year shelf life from the time they are produced. This means that, despite some beliefs about homeopathic remedies not expiring, you should always check and adhere to the expiration date printed on your package.

According to Hyland's, many of their homeopathic medicines, including certain cough syrups, do not have a traditional expiration date printed on the label, a practice exempted by the FDA for homeopathic manufacturers. This means knowing "How long is Hyland's cough syrup good for?" depends on the specific product type, storage conditions, and observing for any signs of change.

Hydrogen peroxide ($H_2O_2$) is a chemically unstable compound that naturally decomposes into water ($H_2O$) and oxygen gas ($O_2$) over time. How long does hydrogen peroxide stay effective depends heavily on whether the bottle is sealed or opened, with the shelf life dramatically decreasing once the seal is broken.

Most over-the-counter decongestant nasal sprays are safe to use for only a limited time after opening, typically 30 to 90 days, even if the manufacturer's printed expiration date is months or years away. Knowing the difference is crucial for safety and efficacy, since the act of opening a bottle compromises its sterility.

According to the FDA's Shelf-Life Extension Program, many medications stocked by the military remained stable and potent for years, even decades, beyond their listed expiration dates. The question of *how long before drugs lose their potency* is more complex than the date on the bottle suggests, involving multiple factors from storage conditions to formulation.

In 2019, 2.4 million U.S. adults reported using buprenorphine, with nearly 75% using it as prescribed [1.6.2]. A common question is, **does buprenorphine lose potency over time?** While generally stable, its effectiveness can be compromised by improper storage.

According to standard medical guidelines, an opened vial of bacteriostatic saline is considered safe for repeated use for a maximum of 28 days. This extended shelf life, made possible by an antimicrobial preservative, is a critical feature distinguishing it from single-use solutions and requires strict adherence to proper storage protocols for patient safety.

According to the manufacturer, a multidose bottle of iVIZIA eye drops can be used for up to 90 days after it has been opened [1.2.1, 1.3.1]. Understanding what the shelf life of iVIZIA is involves knowing both the printed expiration date and the in-use time limit.

Liquid dosage forms are a cornerstone of medicine, especially for pediatrics. When considering these formulations, a key question arises for pharmacists and patients alike: **which is more stable, syrup or elixir?** The answer depends heavily on the drug itself and the formulation's ingredients [1.2.2].

According to the American Academy of Ophthalmology, most multi-dose eye drops should be discarded 28 days after opening to prevent contamination and the loss of effectiveness. This guideline directly addresses the question of whether or not **eye drops lose potency over time**, which is a crucial aspect of eye care and medication safety.
