Adverse effects that threaten serious harm, aggravate other medical conditions, or make a person want to stop taking their medications are all examples of drug intolerance. Certain drug interactions can cause adverse effects as well. [1] Patient/guardian preference: A patient or caregiver may prefer a different antipsychotic. This may be due to ...
Possible side effects of olanzapine/fluoxetine include all those of the two component drugs: olanzapine (side effects) and fluoxetine (side effects).Common side effects include suicidal thoughts, increased appetite, weight gain, drowsiness, fatigue, dry mouth, swelling, tremor, blurred vision, and difficulty concentrating.
These side effects are serious and some of them are permanent, and many remain a crucial concern for companies and healthcare professionals and substantial efforts are being encouraged to reduce the potential risks for future antipsychotics through more clinical trials and drug development.
These adverse effects are more likely during rapid changes between antipsychotic agents, so making a gradual change between antipsychotics minimises these withdrawal effects. [159] The British National Formulary recommends a gradual dose reduction when discontinuing antipsychotic treatment to avoid acute withdrawal symptoms or rapid relapse. [160]
The mediation of olanzapine in the central nervous system by P-GP means that any other substance or drug that interacts with P-GP increases the risk for toxic accumulations of both olanzapine and the other drug. [98] Olanzapine is a potent antagonist of the muscarinic M 3 receptor, [99] which may underlie its diabetogenic side effects.
Common adverse effects of olanzapine, occurring from 1–10%, include: Gynecomastia [8] Extrapyramidal symptoms (EPS) (dose-dependent). Tends to produce less extrapyramidal side effects than typical antipsychotics but more extrapyramidal side effects than sertindole, clozapine and quetiapine. [9] [10]
Deprescribing can improve adherence, cost, and health outcomes but may have adverse drug withdrawal effects. More specifically, deprescribing is the planned and supervised process of intentionally stopping a medication or reducing its dose to improve the person's health or reduce the risk of adverse side effects .
The authors noted an apparent superior efficacy of olanzapine to the other drugs in terms of reduction in psychopathology and rate of hospitalizations, but olanzapine was associated with relatively severe metabolic effects such as a major weight gain problem (averaging 9.4 lbs over 18 months) and increases in glucose, cholesterol, and ...
