U.S. Food and Drug Administration Approves Addyi, a Libido-Enhancing Treatment for Females Beyond Menopause
- Regulators broadened the indication of Addyi, a daily drug to address low libido in women, to include women after menopause up to age 65.
- This decision will unlock new treatment options for older women, but health professionals advise that addressing HSDD requires a “whole body approach.”
- Addyi is known to have potentially dangerous interactions with drinking that may lead to syncope, so abstinence from alcohol is recommended.
The federal agency widened the indication of a daily pill to manage low libido in females to include postmenopausal women up to the age of sixty-five.
Before this week's decision, the drug, flibanserin (Addyi), was only approved to address low sexual desire in premenopausal females.
The drug was originally authorized by the FDA in two thousand fifteen, following a protracted and controversial regulatory scrutiny.
Regulators had earlier turned down the drug on two separate occasions, in 2010 and 2013. In both cases, the agency raised concerns about its safety profile, efficacy, and an concerning balance of risks and benefits.
Currently, Addyi is the exclusive pill authorized for hypoactive sexual desire disorder, though the FDA cleared bremelanotide (Vyleesi), an as-needed injectable treatment, in two thousand nineteen.
The founder and CEO of the maker of Addyi praised the FDA’s move to expand the drug’s approval, calling it a “significant step” in advancing and focusing on women's sexual wellness.
Additional specialists in female health expressed support for the decision.
“Previously, options were limited for me to prescribe because everything was for women who were premenopausal and not postmenopausal,” said an obstetrician-gynecologist. “Securing the FDA clearance for this patient population could be crucial to help women after menopause who want to have sexual activity and enjoy sex, but sometimes have issues with libido.”
A professor of obstetrics and gynecology told news outlets that the approval was “quite reasonable” given the clinical evidence.
Although supportive, the expert was measured in her assessment: “The studies showed statistical significance of the drug over the placebo, but the extent of the enhancement is not substantial. Is it worthwhile taking a drug daily and not getting bang for your buck?”
Understanding Flibanserin, the ‘Women's Desire Pill’?
Addyi, which is often called “the women's version of Viagra,” has little in common with the medication from which it gets its informal name.
This medication was initially researched as an antidepressant but was found to be lacking during early studies.
However, researchers noted improvements in measures of sexual function and redirected efforts to the drug’s potential as a therapy for low libido.
Following initial denials, Addyi was approved in 2015 to treat hypoactive sexual desire disorder, following additional research and a significant lobbying effort.
The medication carries a boxed (“black box”) warning for potentially dangerous side effects, including low blood pressure (hypotension) and loss of consciousness, when combined with alcoholic drinks.
The label advises waiting at least two hours after drinking before using Addyi to reduce the risk of fainting. If a person has three or more alcoholic drinks on a single occasion, the instructions recommends not taking the pill entirely.
Assertions about the effects of mixing the drug with drinking eventually led the pharmaceutical company to fund further research examining the interaction. The research, which were small in scale, showed no additional risk of syncope. But medical professionals had reservations.
“These studies aren't very persuasive to me. They are a beginning, but they’re not very big and certainly are short-term,” a health research president stated.
An OB-GYN suggested that this may have been part of the cause why Addyi was not initially cleared for older females.
“Patients have experienced adverse reactions like the syncopal episodes and lightheadedness especially in individuals who have had an drink within two hours of taking the pill. When you get older, you become more susceptible to effects like that,” she said.
Another doctor expressed uncertainty about why the broader approval was capped at 65 years of age.
“It's unclear if that has to do with the complexity of the drug. If you take a list of the dos and don’ts, it’s really wide-ranging. Now that this has been cleared, they need to come out with an easier information sheet because it may affect our prescribing,” he said.
Treating Diminished Sexual Desire in Postmenopausal Women
Notwithstanding the warnings, Addyi could still expand treatment options for HSDD to a different group of females who may find help.
“I believe it will benefit this population better as long as they have no other health issues,” said an OB-GYN.
But it is not a quick fix. In fact, the experts consulted all agreed that the female libido is complex and multifaceted.
So treating low desire means considering everything from partnership issues to shifts in hormone levels.
Postmenopausal females experience a wide variety of changes that can impact libido. Symptoms of menopause encompass:
- sudden feelings of heat
- vaginal dryness
- discomfort with sex
- sleep disturbances
- bladder leakage
According to one expert, treating these issues is often a first step toward improved intimacy.
“When a patient presents with libido issues, my initial inquiry is: Are you experiencing vaginal discomfort? Is intercourse painful?” she said.
The expert recommended both vaginal estrogen and hormone replacement therapy (HRT) as treatments to treat the symptoms of menopause, particularly vaginal dryness.
She expressed hope that the FDA’s recent removal of its “serious” warning on hormone therapy will lead more females to feel less apprehensive about it and to view it as a treatment option.
Androgen therapy is also sometimes used without formal approval to treat low libido in women, although it is not officially approved for it.
But besides medication, doctors say that lifestyle should also be factored in. Conversations about libido almost always begin by focusing on relationships and intimacy.
“I am comfortable recommending flibanserin after discussing it with a patient. But I would also advise them to talk about some of the psychosocial issues going on,” she said.
Additional recommendations for boosting sexual desire include:
- getting more sleep
- exercising
- maintaining an active lifestyle
- applying over-the-counter personal lubricants
- practicing extended intimate stimulation
- using sexual wellness devices or vaginal dilators
“It requires an entire whole body approach to sexuality and menopause in older age,” said an expert. “This involves knowing how your body works, your anatomy, and your sexual needs — in other words, what makes you feel good, what allows you to get excited, and ultimately to have a climax of sexual pleasure.”
