Key takeaways:
- There are not any medical information on GLP-1 receptor agonists used concurrently with isotretinoin.
- The elevated threat for being pregnant with GLP-1 use may add to present considerations about isotretinoin, a teratogenic drug.
Adolescents and younger adults are more and more utilizing GLP-1 receptor agonists for weight administration, elevating considerations amongst some dermatologists who can also prescribe a teratogenic drug like isotretinoin for zits.
Rising information recommend that GLP-1 receptor agonists can also improve fertility, along with selling weight reduction, doubtless as a consequence of direct results on the hypothalamic-pituitary-ovarian axis. As ladies drop a few pounds, they typically regain ovulatory cycles and have improved insulin sensitivity, each enhancing the percentages for being pregnant, in response to Travis W. Blalock, MD, MBA, affiliate professor within the division of dermatology, vice chair of medical operations and director of mohs surgical procedure and cutaneous oncology at Emory College Faculty of Medication. This could possibly be of explicit concern for anybody additionally prescribed isotretinoin, a well-liked zits drug with well-documented teratogenic results.
“It’s a requirement in america for females with childbearing potential to stay on no less than two types of contraceptives whereas on [isotretinoin] remedy,” Blalock and colleagues wrote within the Journal of Medication in Dermatology. “Regardless of these well-known dangers, some information recommend roughly a 3rd of people is probably not totally adherent to being pregnant prevention tips (eg, intercourse with fewer than two types of contraception, failure to stay abstinent, lacking doses of oral contraceptives or in some instances, having fully unprotected intercourse).”
Due to these considerations, dermatologists could think about advocating for extra dependable types of contraceptives, together with reversible contraceptives and intrauterine gadgets or implants, Blalock stated.
Blalock spoke with Healio in regards to the elevated uptake of GLP-1 receptor agonists amongst adolescents and what that would imply when the medication are coprescribed with isotretinoin.
Healio: Folks prescribed isotretinoin should comply with being pregnant prevention tips, but information recommend some individuals nonetheless don’t. How may a GLP-1 receptor agonist add to this threat image?
Blalock: At baseline, sufferers on isotretinoin who don’t comply with the prevention tips could improve their threat of being pregnant, which is discouraged for many who are on isotretinoin. The risks of being pregnant whereas taking isotretinoin are nicely documented, together with heightened threat for miscarriage and delivery defects, to not point out the elevated threat for critical pregnancy-related issues. With early information suggesting that GLP-1 receptor agonists could improve the chance of being pregnant, we may hypothesize greater probabilities of pregnancies, with resultant unhealthy outcomes. After all, this underscores the necessity to examine extra to find out if this can be a actual drawback, and whether it is, mitigate this threat.
Healio: How may GLP-1s improve the chance for being pregnant?
Blalock: We don’t totally perceive the mechanisms of how GLP-1 agonists improve the chance for being pregnant, however a number of pathways could contribute. We all know that there are quite a few medical circumstances that negatively influence fertility, together with diabetes, weight problems and even melancholy. If GLP-1 receptor agonists enhance all or any these circumstances — and there are information to recommend they do — the chance of changing into pregnant will increase. That is nice for ladies attempting to develop into pregnant and doubtlessly dangerous for these attempting to keep away from being pregnant. There are additionally questions relating to how GLP-1 receptor agonists influence the gastrointestinal system and resultant treatment absorption, together with oral contraceptives. Once more, that is all hypothesizing primarily based on early information. The total image as to why GLP-1 receptor agonists improve the chance of being pregnant continues to be unclear.
Healio: How ought to dermatologists counsel sufferers relating to contraception if the affected person is prescribed a GLP-1 and isotretinoin?
Blalock: We really feel that with the restricted information obtainable in regards to the coadministration of those medication, dermatologists must be vigilant in regards to the attainable interplay and convey that to sufferers. Realizing that GLP-1 receptor agonists lower gastric emptying, we have no idea definitively whether or not they influence oral contraceptives. As a result of we have no idea that reply, dermatologists might have to obviously state that to sufferers. Thus, utilizing barrier strategies could possibly be emphasised as a result of their mechanism of motion just isn’t reliant on the gastrointestinal system and due to this fact are much less doubtless impacted by GLP-1 agonists.
Healio: What extra do we have to be taught?
Blalock: Now we have quite a bit to be taught. We have no idea if GLP-1 receptor agonists influence oral contraceptive systemic ranges. We have no idea the complete image of the mechanism behind how GLP-1 receptor agonists improve the chance of being pregnant. We should not have definitive information relating to what GLP-1 receptor agonists by themselves do for zits or different inflammatory dermatologic ailments, for that matter. There are some information suggesting that zits could also be exacerbated by GLP-1 agonists, whereas others imagine that GLP-1s could enhance zits. Now we have a long way to go as we be taught extra about this thrilling drug.
