Meticap is only designed to work on the 1-Clic® standard sized cap & vial found at pharmacies such as Walgreens and other retailers and online prescription companies. Meticap does not work on push-and-turn style of presription vials. Each 6-Pack of Meticaps comes with one sample 1-Clic® vial and cap. If you plan on transferring your current prescription labels to our compatible vials because your current pharmacy does not use the 1-Clic vials, you will also need to add the quantity needed to your cart here as a separate line item.
