Oct. 18, 2023 – For girls who’re overweight, day by day life is wrought with landmines. Whether or not it’s the challenges of air journey as a result of aircraft seats are too small, the necessity to defend themselves from the world’s discriminating eyes, or the good lengths many will go to realize higher well being and the promise of longevity, navigating life as an overweight particular person requires a thick pores and skin.

So, it’s no marvel so many are keen to pay greater than $1,000 a month out of pocket to get their palms on medicine like semaglutide (Ozempic and Wegovy) or tirzepatide (Mounjaro). The advantages of those medicine, that are a part of a brand new class known as GLP-1 receptor agonists, embrace vital and fast weight reduction, blood sugar management, and improved life high quality; they’re unprecedented in a setting the place surgical procedure has lengthy been thought-about the best long-term possibility.

On the flip aspect, the will for fast weight reduction and higher blood sugar management additionally comes with an surprising value. Many ladies dwelling with weight problems who take oral contraceptives are unaware that these medicine – particularly Mounjaro – can intrude with the absorption of contraception capsules and the way nicely they work, making an unintended being pregnant extra possible.

Neel Shah, MD, an endocrinologist and affiliate professor on the College of Texas Well being Science Heart at Houston, stated he has had a number of sufferers grow to be pregnant with out desiring to. 

“It was when Mounjaro got here out in the marketplace once we began utilizing it,” he stated of the drug the FDA accepted for kind 2 diabetes in 2022. “It [the warning] was within the product insert, however clinically talking, I don’t know if it was on the high of suppliers’ minds after they have been prescribing Mounjaro.”

When requested if he believed that we have been going to be seeing a major improve in so-called Mounjaro infants, Shah was certain in his response. 

“Completely. We are going to as a result of the sheer quantity [of patients] will improve,” he stated.

It’s All within the Intestine

One of many ways in which medicine like Mounjaro work is by delaying the time that it takes for meals to maneuver from the abdomen to the small gut. Though information continues to be evolving, it’s believed that this course of – delayed gastric emptying – could have an effect on the absorption of contraception capsules. 

Shah stated one other idea is that vomiting, which is a standard aspect impact of a majority of these medicine, additionally impacts the capsules’ capability to forestall being pregnant. 

And “there’s a chronic interval of ramping up the dose due to the GI [gastrointestinal] negative effects,” stated Pinar Kodaman, MD, PhD, a reproductive endocrinologist and assistant professor of gynecology on the Yale Faculty of Drugs in New Haven, CT. 

“Initially, on the lowest dose, there is probably not a variety of potential impact on absorption and gastric emptying. However because the dose goes up, it turns into extra frequent, and it could actually trigger diarrhea, which is one other situation that may have an effect on the absorption of any treatment,” she stated.

Unanticipated Outcomes, Further Prevention

Roughly 42% of ladies within the U.S. are overweight, 40% of whom are between the ages of 20 and 39. Though these new medicine can enhance fertility outcomes for girls who’re overweight (particularly these with polycystic ovary syndrome, or PCOS), just one – Mounjaro – presently carries a warning about contraception capsule effectiveness on its label. Sadly, it seems that some medical doctors are unaware or not counseling sufferers about this threat, and the information is unclear about whether or not different medicine on this class, like Ozempic and Wegovy, have the identical dangers. 

“Thus far, it hasn’t been a typical factor that we counsel about,” stated Kodaman. “It’s all pretty new, however when we have now sufferers on contraception capsules, we do overview different drugs that they’re on as a result of some can have an effect on efficacy, and it’s one thing to bear in mind.”

It’s additionally unclear if different types of contraception – for instance, contraception patches that ship via the pores and skin – may carry related being pregnant dangers. Shah stated a few of his sufferers who turned pregnant with out desiring to have been utilizing these patches. This raises much more questions, since they ship medicine via the pores and skin straight into the bloodstream and never via the GI system. 

What can ladies do to assist be sure that they don’t grow to be pregnant whereas utilizing these medicine? 

“I actually assume that if sufferers wish to shield themselves from an unplanned being pregnant, that as quickly as they begin the GLP receptor agonists, it wouldn’t be a foul thought to make use of condoms, as a result of the onset of motion is fairly fast,” stated Kodaman, noting additionally that “on the lowest dose, there is probably not a variety of potential impact on gastric emptying. However because the dose goes up, it turns into rather more frequent or may cause diarrhea.” 

Shah stated that in his observe, he’s “been telling sufferers so as to add barrier contraception” 4 weeks earlier than they begin their first dose “and at any dose adjustment.”

Zoobia Chaudhry, an weight problems medication physician and assistant professor of drugs at Johns Hopkins Faculty of Drugs in Baltimore, recommends that “sufferers simply guarantee that the injection and drugs that they take are a minimum of 1 hour aside.”

“More often than not, sufferers do take contraception earlier than bedtime, so if the 2 are spaced, it ought to be OK,” she stated.

Another choice is for girls to talk to their medical doctors about different contraceptive choices like IUDs or implantable rods, the place gastric absorption shouldn’t be going to be a difficulty. 

“There’s little or no analysis on this class of medication,” stated Emily Goodstein, a 40-year-old small-business proprietor in Washington, DC, who lately switched from Ozempic to Mounjaro. “Being an individual who lives in a bigger physique is such a horrifying expertise due to the best way that the world discriminates towards you.”

She appreciates the sensation of being proactive that these new medicine grant. It has “opened up a bunch of alternatives for me to be seen as a full particular person by the medical institution,” she stated. “I used to be keen to take the chance, figuring out that I’d be on these medicine for the remainder of my life.”

Along with being what Goodstein refers to as a guinea pig, she stated she made certain that her major care physician was conscious that she was not attempting or planning to grow to be pregnant once more. (She has a 3 year-old youngster.) Nonetheless, her physician solely talked about the most typical negative effects linked to those medicine, like nausea, vomiting, and diarrhea, and didn’t point out the chance of being pregnant.

“People are actually not speaking in regards to the reproductive implications,” she stated, referring to members of a Fb group on these medicine that she belongs to. 

Like sufferers themselves, many medical doctors are simply starting to get their arms round these brokers. “Consciousness, training, supplier involvement, and having a multidisciplinary group might assist sufferers obtain the targets that they set out for themselves,” stated Shah. 

Clear conversations are key.
