Patient Medication Information: uses, side effects, how to take - Jamp-Quetiapine
Serious Warnings and Precautions
JAMP-Quetiapine belongs to a group of medicines called atypical antipsychotics.
These medicines have been linked to a higher rate of death when used in elderly patients with dementia (loss of memory and other mental abilities).
- JAMP-Quetiapine is not to be used if you are elderly and have dementia.
What is JAMP-Quetiapine used for?
JAMP-Quetiapine is used to treat symptoms of schizophrenia in adults. Not all people with this disorder have the same symptoms. Some of the most common symptoms of schizophrenia may include:
- hallucinations (seeing, feeling, hearing or smelling things that are not there)
- delusions (believing things that are not true)
- paranoia (not trusting others or feeling very suspicious)
- avoiding family members and friends and wanting to be alone
feeling depressed, anxious or tense
JAMP-Quetiapine is also used to treat adults who suffer from manic or depressive episodes in bipolar disorder. Bipolar disorder is a condition with symptoms such as:
- feeling invincible or an all powerful inflated self-esteem
- having racing thoughts, easily losing train of thought
- overreacting to what you see or hear
- misinterpreting events
- speeding-up your activities, talking very quickly, too loudly, or more than usual
- needing less sleep
- having poor judgment
- severe irritability
- feeling sad or hopeless
- loss of interest and enjoyment
feeling tired
JAMP-Quetiapine is not a cure for your condition, but it can help manage your symptoms and help you feel better.
How does JAMP-Quetiapine work?
Antipsychotic medications affect the chemicals that allow communication between nerve cells (neurotransmitters). Illnesses that affect the brain may be due to certain chemicals (dopamine and serotonin) in the brain being out of balance. These imbalances may cause some of the
symptoms you may be experiencing. Exactly how JAMP-Quetiapine works is unknown. However, it seems to adjust the balance of these chemicals.
