What If I Take an Overdose?

Taking an overdose of this drug is unlikely, for various reasons. People who take too much of a progestin hormone such as Plan B may experience nausea and vomiting, but serious problems are not likely to occur.

How Should It Be Stored?

Keep Plan B at room temperature, away from moisture or heat. Make sure to keep this medication and all other medications out of the reach of children.

Is There a Generic Version?

There are generic versions currently available for both the prescription and over-the-counter (OTC) versions of both original (two-step) Plan B and the new Plan B One-Step (see Generic Plan B).

Strengths of Plan B

This medication comes in one strength -- Plan B One-Step, with 1.5 mg of levonorgestrel per tablet, in a pack that contains one tablet. The older version came in a pack with two 0.75-mg tablets.
