These extended‑release caplets are described as providing pain relief for up to eight hours.
Some products are labeled for adults 18 years and older, while others are labeled for ages 12 years and up.
The extended‑release caplets use a bi‑layer (two‑layer) design: one layer for faster acting relief and a second layer for extended release.
The topical cream contains 4% lidocaine and 1% menthol. Adults and children 12 and older are instructed to apply it to affected areas no more than three to four times daily.
Labels warn the products contain acetaminophen and specify not to exceed the daily caplet limits (for example, not more than six extra‑strength caplets in 24 hours) and not to use for more than 10 days unless directed by a doctor.
