Arkolamyl – Olanzapine uses, dose and side effects


5 mg, 10 mg, 15 mg, 20 mg orodispersible tablets 

1. What Arkolamyl is and what it is used for

Arkolamyl contains the active substance olanzapine. Olanzapine belongs to the group of drugs neuroleptics and is used to treat the following mental health conditions:

  • Schizophrenia, a condition with symptoms such as hearing, seeing or sensing something that does not exist, delusions, unusual suspicion, and withdrawal. People with these conditions may also feel depressed, anxious, or tense.
  • Moderate to severe manic episodes, a condition with symptoms such as arousal and euphoria.

Arkolamyl prevents the recurrence of these symptoms in patients with bipolar disorder where treatment with the drug has had an effect in the manic phase.

Olanzapine contained in Arkolamyl may also be approved for the treatment of other conditions not mentioned in this leaflet. Ask your doctor, pharmacist, or another healthcare professional if you have any further questions, and always follow their instructions.
