You're standing in the bathroom, heart racing just a little bit, holding that small plastic box. It's late. Or maybe it's early. Either way, you need to know how to open Plan B because, honestly, that plastic clamshell feels like it was designed by a vault technician. It’s frustrating. You’ve had a long night, or a stressful morning, and the last thing you need is a struggle with tamper-proof industrial plastic.
The reality is that emergency contraception packaging is intentionally difficult. It’s a mix of FDA regulations and theft prevention. Retailers hate when small, expensive items walk out the door, so they encase them in "clamshell" or "blister" packs that require a certain level of finesse—or brute force—to navigate.

The Clear Plastic Outer Box Struggle
Most people first encounter the clear, rigid plastic box. This is the "security" layer. If you bought it over the counter at a place like CVS or Walgreens, it might even have a yellow or red security tag on it. Look closely at the edges. You’ll usually see a small perforated line or a notched tab at the top or bottom. Don't try to use your teeth. Seriously. I've seen people chip enamel trying to get into these things.
If there isn't a clear "pull here" tab, your best bet is a pair of scissors. Cut along the side edge, away from the center, so you don't accidentally nick the internal instructions or the blister pack itself. Sometimes, these boxes have a "slide" mechanism. You have to press a small plastic lever in while pulling the tray out. It’s like a puzzle. A very high-stakes, annoying puzzle.
Dealing With the Blister Pack
Once you're inside the box, you’ll find the actual medication. It’s a single tablet. Just one. That’s the levonorgestrel 1.5mg dose. It’s usually housed in a foil-backed blister pack.
Here is where people mess up: they try to peel the foil. Most Plan B packs aren't designed to "peel" easily. Instead, you're supposed to push the pill through the foil from the plastic bubble side. Use your thumb. Apply firm, steady pressure right in the center of the bubble. The foil on the back should pop or tear, letting the pill drop out.

Pro tip: Do this over a flat, clean surface like a counter or a table. That pill is tiny. If it pops out and hits the floor, it can roll under a cabinet faster than you can say "emergency contraception." You don't want to be playing hide-and-seek with a $50 pill at 2:00 AM.
Why Is It So Hard to Get Into?
It feels like a conspiracy, doesn't it? It isn't. The "Child-Resistant Packaging" (CRP) standards are set by the Poison Prevention Packaging Act. While Plan B is generally safe for adults, the packaging has to meet certain "senior-friendly but child-resistant" metrics.
Furthermore, the Levonorgestrel tablet is sensitive to moisture and light. That tough foil isn't just to annoy you; it’s a barrier. According to the manufacturer, Foundation Consumer Healthcare, the integrity of that seal is what ensures the hormone stays shelf-stable for several years. If you find a pack that is already open or the foil is broken, do not use it. Go back to the pharmacy and exchange it.
What If the Pill Breaks?
If you were a bit too aggressive while learning how to open Plan B and the pill cracked or crumbled, you can still take it. Just make sure you swallow all the pieces. The efficacy depends on the full 1.5mg dose hitting your system at once. If half the pill ends up as dust on the floor, you might not be getting the protection you need.

Take it with water. You don't need to eat first, though some people find that a small snack helps prevent the nausea that sometimes comes with a high dose of hormones.
Timing and Next Steps
Now that you've got the package open and the pill in hand, remember that time is the biggest factor here. The "72-hour window" is the standard advice, but honestly, the sooner the better. Research published in The Lancet and guidelines from the American College of Obstetricians and Gynecologists (ACOG) emphasize that levonorgestrel is most effective when taken within 24 hours.
- Take it now. Don't wait until "the right time."
- Check your meds. If you are on certain medications for seizures or TB (like rifampin), Plan B might be less effective.
- Track your cycle. Expect your next period to be a little weird. It might be early, late, heavier, or lighter. That's normal.
- Don't panic. If you vomit within two hours of taking the pill, you likely need to open a second pack and take another one, as the first may not have been absorbed.
If you’re finding the cost or the "clamshell struggle" too much, check out generic versions like Take Action, My Way, or Option 2. They are chemically identical but often come in slightly easier-to-open cardboard-based packaging.
Practical Summary for Immediate Action
Stop fumbling with the corners. Find a pair of kitchen shears and cut the side of the hard plastic outer shell. Once you have the blister card, place it on a table, plastic side up, and use the pad of your thumb to push the pill directly through the foil backing. Swallow the tablet immediately with a full glass of water. If you have questions about your specific health history, a quick call to a 24-hour nurse line or your local pharmacist can provide clarity without the stress of a Google rabbit hole.
