(CNN) — Emily Padgett has spent months trying to get her hands on estrogen patches, bouncing between pharmacies, transferring prescriptions and switching brands three times.
For a couple of anxious weeks in January, she had to go without them entirely.
“There’s definitely some symptoms that I noticed popping back after I went off of the patch for a while, and they still haven’t completely gone away since then,” said Padgett, who is in perimenopause.
After a long stretch of uncertainty, she is now finally able to access estrogen patches at a small independent pharmacy in her neighborhood. But each time she walks up to the counter to refill her prescription, she worries about hearing those three words she’s come to fear: “Out of stock.”
For many women in the United States who encounter drenching night sweats, sudden hot flashes, debilitating exhaustion and other menopause-related symptoms, small estradiol patches have become a steady source of relief.
That relief is becoming harder to find – and doctors brace themselves for potentially more shortages to come.
Manufacturers point to a rise in demand, driven by a greater awareness of menopause care and recent action by federal regulators to clarify the risks versus benefits of hormone therapies.
The estradiol patch, a tiny square worn on the skin, may be discreet, but its impact is powerful. It delivers a consistent stream of estrogen to the body, which gets absorbed through the skin. The estrogen hormone naturally declines with age and when levels drop during menopause, symptoms can surge. During perimenopause, the transitional period before menopause, levels of estrogen can start to decrease.
Padgett, a 49-year-old mother of two in Atlanta, said that she had to go those two weeks in January without medication because she could not find a pharmacy that had estrogen patches in stock.
“It’s just an inconvenience more than anything,” Padgett said.
Her perimenopause symptoms of irritability, insomnia and brain fog came back during that time, and she thinks they were exacerbated by the stress of the estrogen patch shortage.
“I was definitely stressed about not getting them, and so my main symptoms were irritability and waking up in the middle of the night stressed and not sleeping,” she said. “I feel like my symptoms have still not completely gone away.”
After switching from different CVS locations and Amazon to the neighborhood pharmacy that ultimately came through, Padgett said that she is back to her regular routine of applying a twice-weekly estrogen patch – but it is a different brand than she is used to.
“I’m on my third different brand now,” she said, and she still worries about future supply.
Estrogen supply challenges
Estrogen patches are available through a doctor’s prescription only. But lately, some prescriptions are taking longer to fill as supplies run low.
“Manufacturers have been unable to provide sufficient supply of hormone replacement therapies (HRT) over the last several weeks,” CVS spokesperson Amy Thibault said in an email. “When these manufacturer supply interruptions occur, our pharmacy teams make every effort to ensure p
