      Rarely Flunarin can cause elevation of liver enzymes, therefore, it is better to stop it and wait for three months and test them again. if the liver functions are not improving then you need to think about another cause that will affect liver.

      In addition, it is better to check for other progressive liver diseases. Therefore, your child should be seen by a pediatrician.

      Non Drowsy Medications that can be taken other than Flunarin are Pizotifen, Propranolol, Topiramate and Gabapentin. You need to discuss with your doctor regarding these medications.

      Sorry, i don't know about any medication that can counter drowsiness, especially alternative therapies. By the way I am a doctor practicing western medicine.

      Surprisingly, there are no good legal medications in western medical practice that can be used to counteract drowsiness.

      Most medications that are in fact developed to promote alertness are used as street drugs with very dangerous side effects. e.g. Amphetamines

      Flunarin can cause drowsiness, but it is not effective as a sleeping pill.
