Finlepsin is known in the states as carbamazepine
an anticonvulsant (anti-seizure ) and specific analgesic (pain relief) for trigeminal neuralgia
It is sometimes used for affective disorders like Bi-polar affective disorder

Siralud or Tizanidine (trade names Zanaflex, Sirdalud) is a drug that is used as a muscle relaxant. It is a centrally acting α2 adrenergic agonist. It is used to treat the spasms related to nerve damage.

Haloperidol (Haldol) is used to treat psychotic disorders (conditions that cause difficulty telling the difference between things or ideas that are real and things or ideas that are not real). Haloperidol is also used to control motor tics (uncontrollable need to repeat certain body movements) and verbal tics

These are some very powerful drugs. I have never heard of this combination being used for PCS, especially the first and last. Muscle relaxants are not uncommon for the injuries associated with concussion.

Let us know how they effect you.

My best to you.

Are you taking any other drugs prescribed by other doctors?
