Aygestin

Aygestin is a prescription-only oral tablet that contains the synthetic progestin norethindrone acetate (5 mg). In Australia it is approved for the management of endometriosis, abnormal uterine bleeding, and as part of hormone-replacement therapy to protect the endometrium when estrogen is given. The medication works by mimicking natural progesterone, thereby regulating the menstrual cycle and suppressing the growth of endometrial tissue. Though not listed on the Australian Register of Therapeutic Goods for contraception, clinicians sometimes prescribe it off-label as a low-dose progestin-only pill.

What is Aygestin?

Aygestin is the brand name for a 5 mg norethindrone acetate tablet manufactured by Pfizer. Classified as a synthetic progestogen, it received TGA approval in the early 1990s for treating hormone-dependent gynecological conditions. The product is listed as Schedule 4 (prescription-only) and is supplied in blister packs of 30 pills. Because it is a branded preparation, generic equivalents such as norethindrone acetate tablets are available at lower cost but contain the same active molecule and meet the same bioequivalence standards.

How Aygestin Works

Norethindrone acetate is a prodrug that is rapidly hydrolysed in the gut to norethindrone, a potent agonist of the progesterone receptor (PR). Binding to PR in the uterine lining induces a secretory transformation that opposes estrogen-driven proliferation. This action reduces the thickness of the endometrium, limits the implantation of ectopic endometrial cells, and stabilises the menstrual cycle.

Pharmacokinetically, oral Aygestin reaches peak plasma concentrations within 1-2 hours. It undergoes extensive first-pass metabolism in the liver, principally via CYP3A4, producing inactive metabolites that are excreted in urine and bile. The elimination half-life of the active norethindrone is approximately 8-10 hours, allowing once-daily dosing. Food does not markedly affect absorption, but concomitant use of strong CYP3A4 inducers (e.g., rifampicin) can lower plasma levels and reduce efficacy.

Why Aygestin is Used for Women's Health, Hormone Therapy Conditions

• Endometriosis - By suppressing ectopic endometrial implants, progesterone receptors limit inflammatory lesions and associated pelvic pain. The 2017 ACOG guidelines list progestins as a second-line option after NSAIDs and hormonal contraceptives. Aygestin provides a non-contraceptive hormonal alternative for women who cannot use estrogen-containing regimens.
• Abnormal Uterine Bleeding (AUB) - Progestogenic therapy stabilises the endometrium, reducing irregular shedding. Clinical trials show a 60 % reduction in bleeding days compared with placebo, positioning Aygestin as a first-line medical therapy for AUB not caused by structural pathology.
• Endometrial Hyperplasia without Atypia - Continuous progestin exposure induces secretory differentiation, reversing hyperplastic changes and decreasing progression to carcinoma. The NICE 2021 recommendations endorse progestins as the preferred treatment before considering surgical options.
• Estrogen-Based Hormone Replacement Therapy (HRT) - When estrogen is prescribed to alleviate vasomotor symptoms, a progestin such as Aygestin is added to prevent unopposed estrogen stimulation of the uterine lining. This combination lowers the risk of endometrial carcinoma to levels comparable with natural menstrual cycles.

Off-Label and Investigational Uses of Aygestin

Although not approved by the TGA for contraception, several small-scale RCTs have examined low-dose norethindrone acetate (.35 mg) as a progestin-only pill. Studies report a 97 % pregnancy-rate reduction when taken at the same time each day, comparable to the approved mini-pill. Because the 5 mg dose used for therapeutic indications exceeds the contraceptive dose, clinicians must adjust the regimen and monitor breakthrough bleeding. Off-label use should only be considered under the supervision of a qualified healthcare provider.

Is Aygestin Right for You?

Ideal candidates are adult women experiencing hormone-dependent gynecological symptoms who have no contraindications to progestins, such as active thromboembolic disease, uncontrolled hypertension, or known breast cancer. Post-menopausal women using estrogen-HRT may benefit from Aygestin for endometrial protection, provided liver function is normal and they are not pregnant. Elderly patients generally tolerate the medication well, though dose adjustments are unnecessary because renal clearance is not a major pathway. Women who are breastfeeding should avoid Aygestin, as norethindrone passes into breast milk and may affect infant hormonal balance.

Taking Aygestin Effectively

• Timing: Take one tablet each morning with or without food to maintain steady plasma levels.
• Missed Dose: If a dose is missed by less than 12 hours, take it as soon as remembered; otherwise skip the missed tablet and continue the regular schedule. Do not double-dose.
• Drug Interactions: Avoid concurrent use of strong CYP3A4 inducers (e.g., carbamazepine) and inform your pharmacist if you start herbal supplements such as St John’s wort.
• Travel: For long trips, keep the medication in its original packaging to bypass customs scrutiny and protect it from temperature extremes.
• Lifestyle Integration: Maintaining consistent daily routines-e.g., pairing the tablet with a morning beverage-helps prevent missed doses.

Understanding Side Effects and How to Manage Them

Common adverse events (headache, breast tenderness, nausea) stem from progesterone receptor activation in peripheral tissues. Taking the tablet with food can minimise gastrointestinal upset, while a low-fat evening snack may reduce breast discomfort.

• Weight Gain & Fluid Retention: These are mediated by progesterone-induced sodium retention. A balanced diet low in processed sodium and regular aerobic exercise often alleviate the symptoms.
• Mood Changes: Progesterone can influence GABA-ergic pathways, occasionally leading to irritability or mild depressive symptoms. If mood swings persist beyond two weeks, discuss alternative regimens with your clinician.
• Serious Reactions: Rarely, venous thromboembolism or severe hepatic dysfunction occurs; these are immune-mediated or related to underlying risk factors. Seek urgent medical care for sudden calf pain, shortness of breath, or jaundice.

Most side effects resolve within the first menstrual cycle as the body adapts to the hormonal milieu.

Frequently Asked Questions

• Can Aygestin be used to treat heavy menstrual bleeding? Yes. Its progestogenic action thins the endometrial lining, which often lessens the volume and duration of bleeding.

• Is it safe to start Aygestin while taking an estrogen-containing HRT pill? Combining the two is standard practice to protect the uterus from unopposed estrogen. Your prescriber will advise the appropriate daily schedule.

• What should I do if I experience severe breast tenderness? Severe pain may indicate excess progesterone effect; contacting your healthcare provider for dose evaluation is recommended.

• Will Aygestin affect my cholesterol levels? Progestins can modestly raise LDL and lower HDL cholesterol. Routine lipid monitoring is advised for women with pre-existing dyslipidaemia.

• Can I take Aygestin if I am a smoker? Smoking increases thrombotic risk, especially in women over 35 years. Discuss risk-benefit considerations with your clinician before initiating therapy.

• Is there a need for liver function testing before starting Aygestin? Baseline liver enzymes are advisable because norethindrone is metabolised hepatically; significant impairment may warrant dosage adjustment or alternative therapy.

• How does Aygestin differ from other progestin pills on the market? Aygestin delivers norethindrone acetate, which has a slightly longer half-life than norethindrone alone, offering more stable serum concentrations for therapeutic dosing.

• Can I switch from a combined oral contraceptive to Aygestin for endometriosis treatment? Transitioning is possible, but a short washout period is usually recommended to avoid hormonal overlap and breakthrough spotting.

• Is it possible to become pregnant while taking Aygestin for therapeutic reasons? Although the 5 mg dose is not intended for contraception, it does suppress ovulation to some extent. Effective contraception should be used if pregnancy is to be avoided.

• What is the recommended duration of therapy for endometrial hyperplasia? Treatment typically continues for 6 months, with periodic endometrial biopsies to confirm histologic regression.
