1. What is Zalasta and what is it used for

Zalasta contains the active substance olanzapine. Zalasta belongs to a group of medicines called antipsychotics, used to treat the following diseases:

  • Schizophrenia, a disease whose symptoms are hearing, seeing or feeling unreal things, mistaken beliefs, unusual suspicion, and becoming withdrawn. People suffering from these diseases may also be depressed, anxious or tense.
  • Moderate to severe manic disorder, characterized by symptoms such as excitement or euphoria.

Zalasta has been shown to prevent the recurrence of these symptoms in patients with bipolar disorder whose manic episodes have responded to treatment with olanzapine.

2. What you need to know before you take Zalasta

Do not take Zalasta

How to take Zalasta

Zalasta tablets crumble easily, so they should be handled with care. Do not handle the tablets with wet hands because they can crumble. Remove the tablet from the packaging as follows:

  1. Hold the blister by the sides and separate an individual packaging from the rest of the blister along the perforations.
  2. Pull the aluminum edge and remove it completely.
  3. Let the tablet fall into your hand.
  4. Place the tablet on your tongue immediately.

Four illustrated steps: opening the blister, folding the patch, applying to the skin, and pressing with the hand

Within a few seconds, the tablet begins to disintegrate and can be swallowed with or without water. The mouth should be empty before placing the tablet on the tongue.

You can also put the tablet in a cup or glass of water. It should be drunk immediately.

Contact your doctor immediately if you have:

  • unusual movements (a frequent side effect that can affect up to 1 in 10 people), especially of the face or tongue.

Very common side effects (which can affect more than 1 in 10 people) include weight gain, drowsiness, and increased prolactin levels in the blood. In the early stages of treatment, some people may feel dizzy or faint (with slower heartbeats), especially when getting up from a lying or sitting position. This feeling usually disappears on its own, but if it does not, consult your doctor.

Common side effects (which can affect up to 1 in 10 people) include changes in the levels of some blood cells, circulating lipids, and temporary increases in liver enzymes at the start of treatment, increased blood sugar and urine levels, increased uric acid and creatine phosphokinase levels in the blood, increased appetite, dizziness, agitation, tremors, unusual movements (dyskinesia), constipation, dry mouth, skin rash, loss of strength, excessive fatigue, fluid retention that causes swelling of the hands, ankles, or feet, fever, joint pain, and sexual dysfunctions such as decreased libido in men and women or erectile dysfunction in men.

Uncommon side effects (which can affect up to 1 in 100 people) include hypersensitivity (e.g., inflammation of the mouth and throat, itching, skin rash), diabetes or worsening of diabetes, occasionally related to ketoacidosis (acetone in blood and urine) or coma, seizures, in most cases related to a history of seizures (epilepsy), muscle stiffness or spasms (including eye movements), restless legs syndrome, speech problems, stuttering; slow pulse, sensitivity to sunlight, nosebleeds, abdominal distension, memory loss or forgetfulness, urinary incontinence, loss of ability to urinate, hair loss, absence or decrease of menstrual periods, and changes in the mammary gland in men and women, such as abnormal milk production or abnormal growth.

Severe allergic reactions, such as Drug Reaction with Eosinophilia and Systemic Symptoms (DRESS), have been reported. DRESS initially manifests with symptoms similar to those of the flu, with a skin rash on the face that then spreads to other areas, fever, swelling of the lymph nodes, elevated liver enzyme levels in blood tests, and an increase in a type of white blood cell (eosinophilia).

During treatment with olanzapine, elderly patients with dementia may suffer from stroke, pneumonia, urinary incontinence, falls, excessive fatigue, visual hallucinations, a rise in body temperature, skin redness, and walking problems. Some deaths have been reported in this particular group of patients.

Zalasta may worsen symptoms in patients with Parkinson's disease.
