Tamoxifen is a key hormone therapy for estrogen receptor-positive breast cancer, and the prescribed duration of taking it can vary significantly, often spanning 5 to 10 years. The question, 'How long is tamoxifen 20 mg good for?', can refer both to the length of a patient's prescribed treatment and the shelf life and stability of the drug itself.

Manufacturer testing establishes a specific expiration date to ensure a medication's maximum potency and safety. A product like Neosporin that is 10 years past this date is considered unsafe, unreliable, and potentially harmful.

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 2023, contaminated over-the-counter eye drops were linked to over 80 infections, 14 cases of vision loss, and even four deaths [1.9.1]. This highlights a crucial question: What happens if you use eye drops after 30 days of opening? The answer involves risks of contamination and reduced effectiveness [1.2.1, 1.2.3].

Since 1979, the U.S. Food and Drug Administration (FDA) has required expiration dates on all medications [1.2.1, 1.3.2]. If you're wondering **how long are ibuprofen 800 mg tablets good for?**, the answer depends on several factors, including storage conditions and the risks you're willing to take.

Did you know that if an injectable medication like semaglutide is improperly stored or mishandled, its active ingredients can degrade, reducing its potency and effectiveness?

The United States Food and Drug Administration (FDA) has required expiration dates on all medications, including gabapentin, since 1979. A significant period like 4 years after this date is well past the manufacturer's guaranteed shelf life for gabapentin, which is typically 2-3 years for most formulations. The primary concern with expired gabapentin is not toxicity, but a critical loss of potency that compromises its effectiveness and intended therapeutic benefit.

While medications don't 'spoil' in the same way food does, taking expired gabapentin carries significant risks, primarily a loss of potency that could lead to ineffective treatment. The expiration date guarantees a drug's full quality and effectiveness, but improper storage can accelerate its degradation.

The US Food and Drug Administration (FDA) has required expiration dates on medications since 1979 to ensure their safety and effectiveness. While some non-critical medications may retain potency for a limited time past their date, it is highly inadvisable to take expired antibiotics like amoxicillin, particularly if it is 2 years old. The risks involved can lead to ineffective treatment and potentially serious health complications.
