Estradiol Tablet 1mg

Route: Oral — swallowed tablet.

• Administer once daily at the same time each day, with or without food.
• Swallow whole; do not crush or chew unless directed by the compounding pharmacist.
• Consistent daily administration supports stable circulating estradiol/estrone concentrations.

Dosing is prescriber-determined based on indication, symptom severity, and patient response. The 1 mg oral estradiol dose is a standard reference dose used in clinical trials and practice for menopause management:

• Effective for moderate vasomotor symptoms and bone protection in many patients.
• May be titrated to 2 mg if symptom control is insufficient, or reduced to 0.5 mg in patients achieving adequate relief at lower exposure.
• Concomitant progestogen required for non-hysterectomized patients — prescriber determines regimen.

• Estradiol 1mg (oral): Absorbed through the GI tract with substantial first-pass hepatic conversion to estrone. Circulating estradiol and estrone bind ERα (predominantly uterine, mammary) and ERβ (bone, vasculature, brain) receptors, activate estrogen response elements, and regulate target gene transcription controlling thermoregulatory center activity, osteoclast inhibition, genitourinary epithelial proliferation, and hepatic synthesis of SHBG, triglycerides, and clotting factors.

Clinical Context: The 1 mg oral estradiol dose is commonly used for menopausal hormone therapy, with established efficacy for hot flash reduction and bone density preservation. Hepatic first-pass effects are dose-dependent; monitoring of lipids and coagulation risk factors is relevant at this dose, particularly in patients with baseline hypertriglyceridemia or thromboembolic risk. Progestogen is mandatory in non-hysterectomized patients regardless of dose.

Monitoring Considerations:

• Serum estradiol at follow-up; target therapeutic range varies by indication and patient.
• Annual mammography; endometrial surveillance with progestogen.
• Lipid panel (triglycerides) and blood pressure annually.

Contraindications:

• Estrogen-dependent malignancies, undiagnosed abnormal genital bleeding, active or history of VTE/PE/arterial thromboembolic events, active liver disease, thrombophilic disorders, pregnancy.

Warnings & Precautions:

• Endometrial cancer with unopposed estrogen — progestogen required in intact uterus.
• Breast cancer risk with prolonged use.
• Thromboembolic risk with oral route (hepatic clotting factor induction).
• Triglyceride elevation — monitor in predisposed patients.

Drug Interactions:

• CYP3A4 inducers (rifampin, carbamazepine): reduce estradiol levels. CYP3A4 inhibitors: increase exposure. Thyroid hormone monitoring required.

Common Side Effects: Nausea, breast tenderness, headache, bloating, fluid retention, mood changes, breakthrough bleeding.

Store at controlled room temperature (20–25°C / 68–77°F) in a tightly closed container away from moisture, heat, and light. Keep out of reach of children. Observe the beyond-use date assigned by Genesis Compounding.

Is 1mg the right dose for me?

The 1 mg dose is a commonly used starting or maintenance dose for moderate menopausal symptoms. Your prescriber will evaluate symptom control and serum estradiol at follow-up to determine whether dose adjustment is appropriate.

Do I need a progestogen with this tablet?

Yes, if your uterus is intact. Estrogen alone without progestogen significantly increases endometrial cancer risk. Your prescriber will prescribe an appropriate progestogen concurrently.

Is this FDA-approved?

This is a patient-specific, prescriber-directed 503A compounded preparation from Genesis Compounding and is not FDA-approved as a finished compounded drug product. FDA-approved 1 mg oral estradiol tablets are commercially available.

Can I take this tablet with food?

Yes — oral estradiol may be taken with or without food. Taking with food may help reduce nausea, which is a common early side effect.
