Every medication that a person consumes always has side effects and may not help a person with their symptoms. When a person that has problem sleepiness is consuming a medication that their physician has prescribed them, there is not a guarantee that it is going to help cure the problem.

With problem sleepiness, a person that is taking certain medication might experience the reverse side effects. The medication that has been prescribed to them might not help them to sleep, it might keep them awake, causing more issues. 

These adverse side effects are not helping your body, it is just making it worse on yourself.

If you are experiencing side effect from a medication that your doctor has prescribed for problem sleepiness, then be sure that you contact your doctor immediately. He or she may want you to discontinue the usage of that medicine and try another one.
