Estrace inactive ingredients peg amount?

See the DrugPatentWatch profile for Estrace

What “inactive ingredients” are listed for Estrace (and their amounts)?

“Aubagio? Estrace” is an estradiol product brand, and “inactive ingredients” (also called excipients) and their exact quantities depend on the specific formulation (for example, vaginal cream vs. tablet) and the strength.

The provided information does not include which Estrace product you mean or the specific strength, so I can’t give an accurate peg amount of inactive ingredients without that detail.

Which Estrace product do you have (so I can find the exact inactive-ingredient amounts)?

Please tell me one of the following and I’ll match the inactive-ingredient list to it:

- Form: vaginal cream, vaginal tablet, or other
- Strength: for example, 0.1 mg, 0.5 mg, or 1 mg (or the cream mg/g stated on the box)
- Country/label language (US label vs other)
- If you can, paste the “Inactive ingredients” section text from your package insert

Why the “peg amount” might differ

If you’re asking specifically about “PEG” (polyethylene glycol), the amount can change based on:
- Cream vs tablet formulation
- Strength
- Manufacturer and packaging/label revision year

If you share your label text, I can extract the exact PEG amount

Reply with the product type (cream/tablet) and strength (or paste the inactive-ingredients line(s)), and I’ll provide the exact PEG/“peg” quantity from that label.

Summary

The response generally matches multiple on-label boxed warning and related sections (endometrial cancer with unopposed estrogen, breast cancer risk discussion, cardiovascular/thromboembolic risks, and WHIMS-based probable dementia; also the 'should not be used for prevention of cardiovascular disease or dementia' language for estrogen-alone). However, because the prompt does not provide the exact claim wording being evaluated, one described element is framed too broadly to fully verify against the provided excerpts.

Accurate Statements

Increased risk of endometrial cancer with unopposed estrogen in women with a uterus; progestin reduces risk of endometrial hyperplasia.
SECTION 2.a. Malignant Neoplasms / Endometrial Cancer; boxed warning excerpt (Endometrial Cancer)
Diagnostic evaluation should be undertaken to rule out malignancy in postmenopausal women with undiagnosed persistent or recurring abnormal genital bleeding.
SECTION 2.a. Malignant Neoplasms / Endometrial Cancer; boxed warning excerpt (Endometrial Cancer)
Breast cancer risk is discussed; increased risk is associated with estrogen plus progestin therapy (WHI estrogen plus progestin substudy).
SECTION 2.b. Breast Cancer; boxed warning excerpt (Estrogen plus progestin therapy)
Cardiovascular/thromboembolic risks are increased with estrogen-alone (stroke, DVT) and with estrogen plus progestin (PE, DVT, stroke, MI); discontinue if such events occur or are suspected.
SECTION 1. Cardiovascular Disorders; boxed warning excerpts (Estrogen-alone therapy / Estrogen plus progestin therapy)
Estrogen-alone therapy should not be used for prevention of cardiovascular disease or dementia, and probable dementia risk is reported in WHIMS.
BOXED WARNINGS language excerpt (Estrogen-alone therapy); SECTION 3. Probable Dementia

Unsupported Statements

Any broader/unspecified prevention statement about cardiovascular disease/dementia applies generally, without clearly distinguishing 'estrogen-alone' vs 'estrogen plus progestin' for this product/use.
The provided excerpts specify 'estrogen-alone therapy should not be used for the prevention...' and separately address estrogen plus progestin. The response does not provide exact claim text or product-specific regimen context, so full verification of a broader/generalized statement cannot be confirmed from the supplied excerpts.

Contradictions


Important Omissions

Core contraindication details (e.g., known/suspected breast cancer; active DVT/PE; active arterial thromboembolic disease) were not addressed in the evaluated response content, limiting alignment for contraindications category.
Importance: Moderate

Safety Assessment

Potential Patient Risk: Low
The response focuses on boxed-warning-type risks that are supported by the provided label excerpts (endometrial cancer, breast cancer risk discussion, cardiovascular/thromboembolic risks, and probable dementia/avoid prevention). Missing contraindication and specific adverse-reaction coverage reduces completeness but does not introduce a direct contradiction based on the provided excerpts.

Regulatory Assessment

On Label Yes
Off-label Discussion No
Promotes Unapproved Use No
Hallucination Risk Low

Recommendation

Partially Aligned

Primary Issue
One prevention-related element is framed too broadly (without explicit regimen specificity), which cannot be fully verified from the provided excerpts due to lack of exact claim wording/context.

Suggested Improvement
Evaluate and report support using the exact asserted wording; explicitly tie prevention language to 'estrogen-alone therapy' (and separately 'estrogen plus progestin therapy') as stated in the boxed warning excerpts. Add contraindication and/or adverse reaction details only if they are part of the exact claim text being assessed.
