Sleep problems affect up to 70 million people in the United States alone. Those that are sleep deprived are seeking medical attention for sleeping aids as a result of a study that found a doubling of one’s risk for a heart attack and four times the increased risk for a stroke in those who experience poor sleep.1

If you take warfarin and think you’re one of 70 million with a sleep disorder, you have two things to keep in mind:

How Can It Affect Your Life?

If you get less than your required number of hours of restful sleep, you’ll likely feel it the next day. Feeling tired, groggy or less alert are common of a poor night’s sleep. You may not even know your sleep is not recharging your body’s batteries. Reducing your reaction speed or not having good balance can also be symptoms of poor sleep. You may have an increased risk of falling simply because you have poor quality sleep. To determine how much sleep you need there are many sites that offer assistance. One site, offered by the Harvard Medical School, provides guidance on sleep needs by age.2

Do You Need A Prescribed Aid?

Occasionally, a sleeping aid can be prescribed by your physician. One of the newer prescription drugs promoted to those who have sleep conditions is Belsomra®. Belsomra® is a medication for people who have trouble falling asleep or staying asleep.  The drug’s maker does not suggest that Belsomra® and warfarin interact, suggesting that the two medications can be taken safely together without a dose change of either medication.3

Many sleep aids are available without a prescription. These over-the-counter drugs should be considered having the same side effects of prescription drugs including dependency. Short-term or long term use of any sleep medications is an important topic you should discuss with your healthcare team that manages your warfarin.
