Norplant was effective for five years. The current implant on the US market, Nexplanon, is effective for three years.
you are advised to replace the mirena coil after 5 years, though they probably are effective a while longer than that. Leaving it in much longer, will reduce it's effectiveness. If it's left inside way too long, it can get stuck and be harder to remove. If left very long, it can cause blood loss and pain. Last year we removed a coil that had been in place 20 years. This patient complained about brown loss and pain. It is best to replace your coil after about 5 years to avoid problems with removal later, and guarantee it's optimal effectiveness.
Coil springs typically last up to twenty five years. In fact, they are known to outlive the life of an average car.
I just realized mine was a year past the expiration date, they still seem to be effective.
As long as it is able to dissolve and enter your blood stream through digestion, yes, it is still effective. Otherwise, no.

Yes medical research has shown that Zantac (Ranitidine) is still effective up to 1.5 years after expiration date. After that it begins to lose some of its potency. Like canned food with expiration dates as long as the package is sealed and properly stored it lasts well beyond the expiration date.
My '98 Mondeo Est coil pack failed at ~100k/9 years, symptoms were major loss of power and major movement (rocking back and forth) from the engine.
Years.
Some may work short term but how long depends on the pest. They are more effective for mammals than insects, but not for long. That is why pest companies don't use them. If they worked, they would sell them to you-trust me.
So long as the bottle is intact, the insulin inside it will still be effective.
