Summary
Numerous high-specificity claims (BP thresholds, trial population size/age and numeric BP changes, subgroup effects, and conditional risk language) are not supported by the provided FDA label excerpts, leading to substantial label-misalignment.

Accurate Statements
Annovera is a combined hormonal contraceptive vaginal ring containing ethinyl estradiol and segesterone acetate.
Supported by 11 DESCRIPTION.
Annovera has contraindications including uncontrolled hypertension.
Supported by CONTRAINDICATIONS (uncontrolled hypertension or hypertension with vascular disease) and 5.4.
Annovera has contraindications including a history of blood clots.
Supported by CONTRAINDICATIONS (current or history of DVT/PE; high risk thrombotic diseases).
Annovera has contraindications including a history of stroke.
Supported by CONTRAINDICATIONS (cerebrovascular disease).
Annovera has contraindications including a history of heart attack.
Supported by CONTRAINDICATIONS (coronary artery disease).
Annovera has contraindications including current or past breast cancer.
Supported by CONTRAINDICATIONS (current diagnosis of, or history of, breast cancer).
Annovera has contraindications including liver tumors.
Supported by CONTRAINDICATIONS (liver tumors, acute hepatitis, or severe decompensated cirrhosis).
Annovera has contraindications including certain migraines.
Supported by CONTRAINDICATIONS (headaches with focal neurological symptoms; migraine with aura; age >35 with migraine) and 5.8.
Unsupported Statements
Annovera prescribing information warns against use in people with uncontrolled high blood pressure defined as systolic ≥160 mm Hg or diastolic ≥100 mm Hg.
Provided label excerpts do not define numeric BP thresholds (≥160/≥100); 5.4 only uses terms 'uncontrolled hypertension' / 'hypertension with vascular disease' without the stated cutoffs.
Annovera increases the chance of blood clots in people with uncontrolled high blood pressure.
Contraindication category exists for uncontrolled hypertension/vascular disease, but provided excerpts do not explicitly link uncontrolled hypertension to increased clot risk.
Annovera increases the chance of stroke in people with uncontrolled high blood pressure.
Provided excerpts do not explicitly connect uncontrolled hypertension to stroke risk (though cerebrovascular disease is a contraindication and serious cardiovascular events/stroke are referenced elsewhere).
Annovera increases the chance of heart attack in people with uncontrolled high blood pressure.
Provided excerpts do not explicitly connect uncontrolled hypertension to heart attack risk.
Annovera can worsen high blood pressure in people with uncontrolled high blood pressure.
5.4 supports possible BP increases with CHCs generally and stopping if BP rises significantly, but does not explicitly state 'worsen' specifically in the subgroup 'people with uncontrolled high blood pressure.'
Controlled hypertension defined as systolic <160 mm Hg and diastolic <100 mm Hg may allow Annovera use with close monitoring after assessing individual risks.
Provided excerpts do not define 'well-controlled' using <160/<100 thresholds or state this conditional allowance using those cutoffs.
For people with any history of hypertension, blood pressure should be checked before starting Annovera and regularly during use.
5.4 supports monitoring blood pressure at routine visits and stopping if BP rises significantly, but provided excerpts do not explicitly specify 'before starting' or limit to/mention 'any history of hypertension' as phrased.
In trials of 2,322 women aged 18–35 years, Annovera slightly raised blood pressure in some users.
Provided label excerpt in 14 CLINICAL STUDIES does not include the trial sample size (2,322), age range (18–35), or any blood pressure outcome data.
In those trials, the mean systolic increase was 2.0 mm Hg after 13 cycles with Annovera.
Provided label excerpts do not contain this numeric mean systolic increase value.
In those trials, the mean diastolic increase was 1.1 mm Hg with Annovera.
Provided label excerpts do not contain this numeric mean diastolic increase value.
Discontinuations due to hypertension occurred in 0.2% of users of Annovera.
Provided label excerpts do not contain discontinuation rates due to hypertension.
Women already hypertensive saw greater blood pressure rises with Annovera, prompting recommendations for monitoring or switching methods.
Provided excerpts do not support the claimed subgroup effect ('already hypertensive saw greater rises') or a recommendation to 'switch methods' tied to that finding.
An undesirable outcome/warning with Annovera is increased risk of blood clots, stroke, and heart attack in the setting of uncontrolled high blood pressure.
Provided excerpts reference serious cardiovascular events/stroke and list contraindications, but do not explicitly state that the risks of clots/stroke/heart attack occur 'in the setting of uncontrolled high blood pressure' as stated.
If systolic reaches ≥160 mm Hg or diastolic reaches ≥100 mm Hg while using Annovera, it should be stopped immediately.
5.4 instructs stopping if blood pressure rises significantly, but the provided excerpts do not specify ≥160/≥100 thresholds or 'immediately' tied to those thresholds.
Severe headaches, vision changes, or chest pain while using Annovera signal urgent risks requiring medical help.
Provided excerpts include urgent evaluation guidance for specific vision-related symptoms and discontinuation/evaluation guidance for new/severe headaches, but do not support 'chest pain' in the same urgent-signal phrasing and do not provide the exact 'requiring medical help' framing as stated.
Backup non-hormonal contraception is advised during evaluation if blood pressure reaches thresholds while using Annovera.
Provided excerpts include backup contraception advice only for deviations where the ring is out of the vagina >7 days; they do not specify non-hormonal backup contraception tied to BP thresholds.
Progestin-only options such as implants (Nexplanon) have lower cardiovascular risk profiles than Annovera.
No Nexplanon labeling excerpts are provided and the provided Annovera excerpts do not include comparative cardiovascular risk statements.
Copper IUDs such as Paragard avoid hormones entirely.
No Paragard labeling excerpts are provided to verify this claim against FDA-approved labeling in the prompt.
Contradictions
Important Omissions
Specific contraindication details beyond those evaluated here (e.g., hypersensitivity, hepatitis C drug combinations, undiagnosed abnormal uterine bleeding) were not claimed but are material to full contraindication accuracy.

Safety Assessment
Potential Patient Risk:
Moderate
Several claims introduce unsupported numeric BP thresholds, conditional stopping instructions, and subgroup risk language; these could mislead interpretation of label-based contraindications and management triggers relative to the provided excerpts.

Recommendation
Substantially Misaligned
Primary Issue
Multiple label-misaligned, high-specificity safety and trial-statistics claims are not supported by the supplied FDA label excerpts.
Suggested Improvement
Restrict statements to what is explicitly supported in the provided excerpts (e.g., 'uncontrolled hypertension' without numeric thresholds; monitoring at routine visits and stopping if BP rises significantly; avoid asserting numeric trial BP changes or comparative claims about Nexplanon/Paragard unless their labels are provided).
