Perphenazine is indicated for the treatment of certain mental or mood disorders such as:
- The manic phase of bipolar disorder
Depression is considered a serious medical condition. It can get worse without proper treatment. This condition can be more than a constant state of sadness or feeling blue. Major depression can cause a variety of symptoms. Some affect your mood and others affect your body. Symptoms may also be ongoing or come and go such as:
- Feeling empty or anxious
- Talking or thinking more slowly
- Loss of interest in activities
- Difficulty sleeping through the night
- Sleeping too much
- Decreased energy
- Greater fatigue
- Changes in appetite
In the manic phase of bipolar disorder, it is common to experience feelings of heightened energy, creativity, and euphoria. If you have this type of condition, you may talk a minute, sleep very little, and be hyperactive. You may also feel like you are all-powerful, destined for greatness, or invincible. Common signs and symptoms of the manic phase of bipolar disorder may include:
- Racing thoughts, jumping quickly from one idea to the next
- Talking so rapidly that others can’t keep up
- Highly distractible or unable to concentrate
- Delusions and hallucinations(in severe cases)
- Extremely irritable
- Acting recklessly without thinking about the consequences
Schizophrenia requires lifelong treatment. This is also a serious mental disorder in which people interpret reality abnormally. This may result in some combination of delusions, hallucinations, and extremely disordered thinking. Schizophrenia may also affect behavior that impairs daily functioning and can be disabling. Here are some common early warning signs:
- Depression or social withdrawal
- Suspiciousness or hospitality (an extreme reaction to criticism)
- Expressionless gaze
- Deterioration of personal hygiene
- Inability to cry or express joy
- Oversleeping or insomnia
- Forgetful or unable to concentrate
- Strange use of words or way of speaking
Perphenazine is in the class of medications called phenothiazine antipsychotics. This drug will help you feel less nervous, think more clearly, and take part in your everyday life. This can lessen aggressive behavior and the desire to hurt others or yourself. This will also help decrease hallucinations. Perphenazine restores the balance of certain natural substances in the brain called dopamine. The Food and Drug Administration (FDA) has already approved this prescription. This is supplied as oral tablets with the active ingredient of Perphenazine. Each tablet is available in the dosage forms of 2 mg, 4 mg, 8 mg, and 16 mg.
How does Perphenazine work?
Perphenazine works by blocking a variety of receptors in the brain particularly dopamine receptors. Dopamine is a natural compound called neurotransmitter and is involved in transmitting messages between brain cells. It is a neurotransmitter known to be involved in regulating mood and behavior.
In schizophrenia, this drug blocks the receptors that dopamine acts on. This prevents the overactivity of dopamine in the brain. This also helps to control psychotic illness.
Perphenazine may also be used to control nausea and vomiting. This affects dopamine receptors in an area of the brain that controls nausea and vomiting. Vomiting is controlled by an area of the brain called vomiting center. The vomiting center is responsible for causing feelings of sickness and for the vomiting reflex. It is activated when it receives nerve messages from another area of the brain called the chemoreceptor trigger zone (CTZ). This medication controls nausea and vomiting by blocking dopamine receptors found in the CTZ. This stops the CTZ from sending the messages to the vomiting center.
How to use Perphenazine?
