50
Q

post concussive syndrome meds

A

Amitriptyline. This medication has been widely used for post-traumatic injuries, as well as for symptoms commonly associated with post-concussion syndrome, such as irritability, dizziness and depression.

Amitriptyline may be combined with propranolol (Inderal, Innopran XL) to treat migraine-type headaches.

Topiramate. Commonly used to treat migraines, topiramate (Qudexy XR, Topamax, Trokendi XR) may be effective in reducing headaches after head injury.

Common side effects of topiramate include weight loss and cognitive problems. Gabapentin.

Gabapentin (Gralise, Neurontin) is frequently used to treat a variety of types of pain and may be helpful in treating post-traumatic headaches.

A common side effect of gabapentin is drowsiness.
