An injectable version is available for quick relief of agitated patients.
Because of its potentially serious side effects, Geodon is typically prescribed only after other medications have proved inadequate.
Geodon is prescribed in the treatment of the crippling mental disorder known as schizophrenia.
Geodon is usually taken in capsule form.
If you're uncertain about the risks of any drug you're taking, be sure to check with your doctor before combining it with Geodon.
In some people with heart problems or a slow heartbeat, Geodon can cause serious and potentially fatal heartbeat irregularities.
Injectable Geodon is generally prescribed for no more than a few days.
Many of the drugs prescribed for heartbeat irregularities prolong the QT interval and should never be combined with Geodon.
Other drugs to avoid when taking Geodon include Anzemet, Avelox, Halfan, Inapsine, Lariam, Mellaril, Nebupent, Orap, Orlaam, Pentam, Probucol, Prograf, Serentil, Tequin, Thorazine, Trisenox, and Zagam.
Researchers believe that it works by opposing the action of serotonin and dopamine, two of the brain's major chemical messengers.
The chance of a problem is greater if you are taking a water pill (diuretic) or a medication that prolongs a part of the heartbeat known as the QT interval.
