Each Advil^® PM Liqui-Gels^® capsule contains 200 mg of ibuprofen and 25 mg of diphenhydramine hydrochloride, a gentle sleep aid. The ibuprofen relieves pain over several hours, while the diphenhydramine helps you get a full night’s sleep. The combination of these ingredients not only reduces your pain, it shortens the time it takes to fall asleep and increases the duration of your sleep. The result: a better night's sleep.

The recommended dose of Advil^® PM Liqui-Gels^® is two capsules at bedtime, for adults and children 12 years and older. The two capsule dose contains a combined total of 400 mg of ibuprofen and 50 mg of diphenhydramine hydrochloride. You should not take more than 2 capsules in 24 hours. Stop use and ask a doctor if: pain gets worse or lasts more than 10 days or if sleeplessness persists continuously for more than 2 weeks.

"Solubilized ibuprofen" is ibuprofen that has been completely dissolved in a liquid center inside a soft capsule shell. In the case of Advil^® PM Liqui-Gels^®, the solubilized ibuprofen is in a liquid center inside a soft capsule shell.
