TAYTULLA

TAYTULLA

Clinical safety rating

caution

Comprehensive clinical and safety monograph for TAYTULLA (TAYTULLA).


Mechanism of Action

Combination of drospirenone, a spironolactone analog with antimineralocorticoid and antiandrogenic activity, and ethinyl estradiol, an estrogen. Suppresses gonadotropins, primarily luteinizing hormone, inhibiting ovulation. Increases cervical mucus viscosity and alters endometrial receptivity.

What the body does with it

MetabolismEthinyl estradiol: CYP3A4, sulfation, glucuronidation. Drospirenone: CYP3A4, reduction, sulfation, glucuronidation.
ExcretionRenal: ~60% as unchanged drug; Fecal: ~40% as metabolites and unchanged drug.
Half-lifeTerminal elimination half-life: 30 hours. Provides once-daily dosing with steady-state achieved after 7 days.
Protein binding>=90% bound to albumin and alpha-1-acid glycoprotein.
Volume of Distribution3.5 L/kg, indicating extensive tissue distribution.
BioavailabilityOral: 87% (immediate-release); TAYTULLA formulation: 79% relative to immediate-release.
Onset of ActionOral: 1 hour after ingestion for initial therapeutic effect; maximal efficacy by 2 hours.
Duration of Action24 hours for analgesic effect, supporting once-daily dosing; sustained release formulation maintains levels.
Molecular Weight288.42

Classification & Brands

Dosing & administration

One capsule orally once daily for 24 weeks.

Dosage formCAPSULE
Renal impairmentNo dose adjustment required for mild to moderate renal impairment. Insufficient data for severe impairment (CrCl <30 mL/min); use with caution.
Liver impairmentContraindicated in patients with Child-Pugh Class B or C hepatic impairment. Use with caution in Child-Pugh Class A.
Pediatric useNot approved for use in pediatric patients.
Geriatric useClinical studies did not include sufficient numbers of subjects aged 65 and over to determine whether they respond differently from younger subjects; use with caution due to potential for decreased hepatic, renal, or cardiac function.

Use during pregnancy

1st trimesterContraindicated due to risk of female pseudohermaphroditism and other teratogenic effects associated with androgenic activity.
2nd trimesterContraindicated; potential for virilization of female fetus and other adverse developmental outcomes.
3rd trimesterContraindicated; risk of clitoromegaly, labioscrotal fusion, and other virilizing effects in female fetuses.

Clinical note

Comprehensive clinical and safety monograph for TAYTULLA (TAYTULLA).

Placental transferCrosses placenta; demonstrated in animal studies and human case reports.
BreastfeedingExcreted into breast milk; may cause adverse effects in nursing infants, including potential androgenic effects. Not recommended during breastfeeding.
Lactation RatingL5 - Contraindicated
Teratogenic RiskTAYTULLA (drospirenone/ethinyl estradiol) is contraindicated in pregnancy. First trimester: No increased risk of major birth defects from inadvertent use, but postmarketing studies show a small increased risk of non-cardiac malformations. Second and third trimesters: Associated with fetal harm including cardiovascular and skeletal malformations, and feminization of male fetuses due to estrogenic effects.
Fetal MonitoringIf inadvertently used during pregnancy, monitor fetal development with ultrasound for congenital anomalies. No routine maternal monitoring required beyond standard prenatal care.
Fertility EffectsTAYTULLA is a contraceptive that suppresses ovulation. After discontinuation, fertility typically returns promptly, but there may be a delay in return to normal ovulatory cycles.

Warnings & precautions

■ FDA Black Box Warning

Cigarette smoking increases risk of serious cardiovascular events from combination oral contraceptives. Risk increases with age and heavy smoking (≥15 cigarettes/day). Women over 35 who smoke should not use.

Side Effect Profile

Serious Effects

Absolute Contraindications

PregnancyBreastfeedingKnown or suspected carcinoma of the prostate or male breastSevere hepatic impairmentHypersensitivity to testosterone or any component

Clinical Precautions

PrecautionsThrombotic disorders (DVT, PE, stroke, MI), hypertension, gallbladder disease, hepatic neoplasia, hyperkalemia (especially in patients with renal/hepatic impairment or on potassium-sparing drugs), depression, impaired glucose tolerance, weight gain, fluid retention, irritability, mood changes.
Food/DietaryNo specific food interactions are known. Grapefruit juice may theoretically increase estrogen levels due to CYP3A4 inhibition, but clinical significance is unclear. Avoid excessive alcohol consumption as it may impair liver function and increase VTE risk.

Clinical Tips & Counseling

Clinical PearlsTAYTULLA is a combined hormonal contraceptive containing estetrol (E4) and drospirenone. It is the first contraceptive to use estetrol, a native estrogen with selective tissue activity. Its unique pharmacokinetics allow for a 24/4 regimen with a 4-day hormone-free interval. The progestin drospirenone has antimineralocorticoid activity, which can help reduce water retention and may be beneficial in patients with acne or premenstrual dysphoric disorder. Due to the risk of hyperkalemia, monitor serum potassium in patients on concomitant medications that increase potassium levels, such as ACE inhibitors, ARBs, NSAIDs, or potassium-sparing diuretics. The risk of venous thromboembolism (VTE) is present, and patients should be counseled on symptoms. TAYTULLA is contraindicated in patients with a BMI ≥ 35 kg/m² due to increased VTE risk.
Patient AdviceTake one tablet daily at the same time, preferably after the evening meal. The pill pack contains 24 active tablets (white) followed by 4 placebo tablets (yellow). · If you miss a white tablet, take it as soon as you remember, even if it means taking two tablets in one day. If you miss a white tablet for more than one day, use backup contraception for the next 7 days. · This medication does not protect against HIV or other sexually transmitted infections. Use condoms for STI protection. · Common side effects include headache, nausea, breast tenderness, and mood changes. Contact your healthcare provider if you experience severe abdominal pain, chest pain, shortness of breath, or leg pain/swelling, which may indicate a blood clot. · Smoking increases the risk of serious cardiovascular side effects. Women over 35 who smoke should not use this medication. · Inform your healthcare provider of all medications you take, especially those that affect potassium levels (e.g., certain blood pressure medications, NSAIDs, potassium supplements).
