It affects around one in seven Australian women and there is currently no cure.\nWhy has the government decided to subsidise Visanne? Here’s how this daily tablet works and who it might help.\nWhat is Visanne and how does it work?\nVisanne is a synthetic drug from a family of hormones called progestins. It works by reducing the production of another hormone called estradiol.\nEstradiol regulates female reproductive cycles and is the primary female sex hormone. But it also promotes the growth of the endometrium – the tissue that lines the uterus.\nLimiting estradiol’s production in the body helps to lessen the crippling effects of the condition by curbing the abnormal growth of this tissue.\nIn a 2023 study, Visanne was shown to be effective in controlling the symptoms of endometriosis. After a year of treatment with a once daily 2 milligram dose of the drug, women experienced an average reduction of endometrium growth by around 26%. This led to a significant reduction in the condition’s effects, particularly in alleviating period pain.\nIn another 2022 study (funded by the company behind the drug), researchers examined its use in nearly 900 women across six countries. They found more than 90% of them reported a drop in endometriosis-associated pelvic pain with drug treatment.\nAre there side effects?\nLike all drugs, Visanne has risks and potential side effects.\nThe most common effects include headache, breast discomfort, hot flushes, acne, hair loss, abdominal and back pain, weight gain, vaginal bleeding and unusual weakness.\nIn the 2022 study, two out of five patients reported side effects related to Visanne, including vaginal hemorrhage (10.4%), bleeding between periods (metrorrhagia – 7.3%) and skipped periods (amenorrhea – 6.4%).\nThe intensity of side effects often lessen over time. But it can mean those who decide to take Visanne may be balancing pain relief with a range of other new symptoms.\nWhile some endometriosis treatments are associated with a loss of bone density and an increased risk of osteoporosis later in life, the manufacturer claims the drug has no, or very little, impact on bone mineral density.\nHow much will it cost?\nPreviously, the annual cost of Visanne was A$800 to patients. On the PBS, the price of the daily tablets will reduce to around $380 per year, or around $90 for pension and concession card holders.\nBut the Australian government will more than make up the extra expense through the benefits of increasing accessibility of the drug.\nWhy has it been added to the PBS?\nThe primary consideration for listing a drug on the PBS is its cost-effectiveness. This means the drug must provide a significant health benefit when compared with the cost of existing treatments.\nEndometriosis has been calculated to cost the Australian economy at least $7.8 billion per year.\nHalf of women who have endometriosis are reported to have to manage their condition at work, with many having to reduce their working hours. A 2021 study by academics at Western Sydney University found one in six women with endometriosis have lost their jobs due to their endometriosis.\nSolutions for helping women to remain and be effective in the workforce are essential to Australia closing the gender pay gap.\nHowever the cost of Visanne remains high for many individuals, who will still be paying close to $400 a year to reduce their pain and maintain a high quality of life. And many women may need to continue to take other drugs (such as paracetamol) alongside Visanne, further adding to the cost.\nIs Visanne right for you?\nVisanne is just one available treatment for endometriosis.\nThere are other effective and safe treatments that are already listed on the PBS, such as combination oral contraceptives, gonadotrophin-releasing hormone drugs and long-acting implants that slowly release progestogens.\nIt is important to note for some women who take the drug, Visanne can stop ovulation and also make it more difficult to become pregnant.\nIf you suffer from endometriosis, and your current medications are not sufficient in reducing the pain and inflammation, speak to your doctor. They can determine if a change to Visanne is right for you.","source_license":"CC0","license_restricted":false}
