Many people encounter oxytocin in the context of labor and delivery, but questions often come up about how it works and what else it has been studied for. Here is a plain-language look at what the label and available data actually show.

Key takeaways

  • Oxytocin is labeled among the oxytocic drug class, along with related hormone classifications.
  • The compound has been registered in 1,401 clinical trials, spanning many areas of research beyond its labeled use.
  • FDA safety reports are dominated by terms related to pregnancy exposure rather than a single dominant side effect.
  • No boxed warning is present on the label.
  • Trials in the sample include research on functional neurological disorder, labor induction, and schizophrenia.

What Oxytocin Is

Oxytocin is classified on its label under pharm classes that include Oxytocic, Adrenocorticotropic Hormone, and Thyroid Stimulating Hormone categories. It is a naturally occurring peptide hormone, identified in chemical databases under PubChem CID 439302. The label does not provide a specific mechanism of action description in the data reviewed.

What Oxytocin Is Approved For

The available label text for this product centers on a consumer-style dosing instruction rather than a detailed indications statement, so specific approved uses cannot be summarized from it here. The brand name GUNA-GERIATRICS appears in the data reviewed. No boxed warning is present on this label.

What the Evidence Shows

Oxytocin has been studied across 1,401 registered clinical trials. Among the sampled studies, a completed trial examined oxytocin's role in interoception among people with functional neurological disorder. A separate, terminated open-label study looked at intranasal oxytocin in people with schizophrenia. Another completed phase 2 trial studied a different compound, tafoxiparin, for cervical ripening in pregnant women, with oxytocin relevant to the labor context of that research.

Reported Side Effects

FAERS reports, which reflect the number of times a reaction was reported and not confirmed incidence or causation, are led by terms tied to pregnancy: foetal exposure during pregnancy (443 reports), maternal exposure during pregnancy (432), and exposure during pregnancy generally (361). Other frequently reported terms include drug ineffective (401 reports) and premature delivery or premature baby outcomes (206 and 160 reports, respectively). Hypotension (191 reports) and off label use (191 reports) also appear among the more common entries.

FAQ

What is oxytocin used for?
Oxytocin is labeled under drug classes that include oxytocic, meaning it relates to uterine and labor-associated activity, along with other hormone-related classifications. The specific label reviewed here did not provide a detailed indications statement to summarize. It has also been the subject of broad clinical research well beyond any single labeled use.
Does oxytocin have a boxed warning?
No, the label data reviewed for this product does not include a boxed warning.
What side effects are most reported with oxytocin?
FDA safety reports (FAERS) are most frequently associated with pregnancy exposure terms, such as foetal and maternal exposure during pregnancy, along with reports of drug ineffectiveness, premature delivery, and hypotension. These are counts of submitted reports, not confirmed rates of incidence or proof that oxytocin caused the reaction. Hypotension and off label use were each reported 191 times in the data reviewed.
Is oxytocin only used in pregnancy and labor?
While its oxytocic classification links it to uterine and labor contexts, clinical trial data show oxytocin has been studied in over 1,400 registered trials covering many other areas. Examples in the available sample include research on functional neurological disorder and on schizophrenia, using intranasal administration in the latter case.
What is the PubChem identifier for oxytocin?
Oxytocin is catalogued under PubChem CID 439302, which can be used to look up its chemical structure and properties in public databases.
