From the Guidelines
Cyproheptadine discontinuation is likely to cause weight loss.
Rationale
- The provided evidence suggests that cyproheptadine is used as an appetite stimulant to help patients gain weight and improve overall health 1.
- Studies have shown that cyproheptadine improves weight and appetite in the short term, with a clinically relevant effect size for weight/age and body mass index for age 1.
- Although the evidence is moderate-grade and based on small studies, the overall trend suggests that cyproheptadine has a positive effect on weight gain.
- Therefore, it is reasonable to assume that discontinuing cyproheptadine would likely lead to weight loss, as the appetite-stimulating effect would be removed.
- It is essential to note that the evidence is not strong, and more research is needed to confirm this association, but in the context of real-life clinical medicine, caution should be exercised when discontinuing cyproheptadine.
From the Research
Cyproheptadine Discontinuation and Weight Loss
- There is no direct evidence to suggest that cyproheptadine discontinuation causes weight loss 2, 3, 4, 5, 6.
- Cyproheptadine is known to stimulate appetite and promote weight gain in individuals with poor appetite 2, 3, 4.
- Studies have shown that patients who take cyproheptadine experience significant increases in weight and body mass index 2, 3.
- The discontinuation of cyproheptadine may lead to a decrease in appetite and potentially a decrease in weight, but this is not explicitly stated in the available evidence.
- Further research is needed to determine the effects of cyproheptadine discontinuation on weight loss.
Mechanism of Action
- Cyproheptadine is an antihistamine and antiserotonergic agent that stimulates appetite and promotes weight gain 2, 3, 4.
- The exact mechanism of action of cyproheptadine on appetite and weight gain is not fully understood, but it is thought to involve the serotonergic feeding mechanism 3.
- Cyproheptadine may also have an effect on body composition, with one study showing an increase in body mass index (BMI) in patients taking the medication 5.
Clinical Implications
- Cyproheptadine is a safe and effective treatment option for individuals with poor appetite, including those with functional gastrointestinal disorders and cystic fibrosis 2, 4, 5.
- The use of cyproheptadine may be beneficial in promoting weight gain and improving nutritional status in individuals with chronic anorexia 5.
- However, the potential benefits and risks of cyproheptadine use must be carefully considered, particularly in individuals with a history of neuropsychiatric disorders or those taking antiretroviral medications 6.
