It's well known that caffeine negatively affects sleep, but you don't only need to worry about having a cup of coffee too late in the day—you should also be checking the contents of any medication you're taking close to bedtime. Many common OTC meds contain caffeine, from Excedrin to Midol, so check the ingredients to make sure that pill you pop before bed won't keep you up.

Caffeine is often used as an ingredient in headache medications.

While it may seem like a strange addition to medication, caffeine is commonly found in headache and migraine medications.

"During a headache, blood vessels swell, tighten or go through other changes, causing an increase in blood flow around the brain. This increases blood flow pressures surrounding nerves, which send pain messages to the brain. This brings on the headache," explain the experts at the Mayo Clinic. "Caffeine has vasoconstrictive properties, meaning that blood vessels narrow to restrict blood flow, thereby alleviating the pain."

Don't take any medication that contains caffeine less than six hours before bedtime.

A Nov. 2013 study from The Journal of Clinical Sleep Medicine found that "caffeine taken six hours before bedtime has important disruptive effects on sleep." So, if you tend to go to bed around 10 p.m., don't take any OTC medications with caffeine past 4 p.m. unless you want to be up all night.

The Sleep Foundation notes that some people may need an even longer period without caffeine before bed, so keep track of how it affects your sleep, adjusting the length of time between the OTC meds and bedtime as needed.

There are caffeine-free versions of some popular headache medications.

If you need to take a pain reliever before bed, it's best to seek out one that doesn't contain caffeine. Midol sells a caffeine-free pill, and Excedrin has a special nighttime formula that is also devoid of caffeine.

Additionally, you can stick to other common OTC pain relievers such as Advil, Tylenol, Motrin, and Aleve.
