Last clinically reviewed: July 2026 · OpiCalc Medical Review Team
BYQLOVI (revumenib) is a menin inhibitor that binds to the menin protein, blocking its interaction with mixed lineage leukemia (MLL) fusion proteins and thus inhibiting leukemogenesis.
Sotradecol (sodium tetradecyl sulfate) is a sclerosing agent that acts by irritating the intimal endothelium of veins, causing inflammation, thrombosis, and subsequent fibrosis, leading to occlusion of the treated vein.
Treatment of relapsed or refractory acute leukemia with a lysine methyltransferase 2A (KMT2A) gene translocation in adults and pediatric patients 1 year and older
Uncomplicated spider veins (telangiectasias) and reticular veins of the lower extremities,Small, uncomplicated varicose veins
BYQLOVI (bictegravir/emtricitabine/tenofovir alafenamide) is administered orally as a single tablet (50/200/25 mg) once daily with or without food.
0.5 m L per injection site, multiple sites per session; maximum volume 10 m L per session; intravenous (sclerotherapy) administration; frequency every 4-6 weeks.
Terminal elimination half-life is approximately 12 hours (range 10–14 hours) in patients with normal renal function; prolonged in renal impairment.
Terminal elimination half-life approximately 5-6 hours; clinical effect persists longer due to local action at injection site
Primarily metabolized by CYP3A4 and CYP2D6.
Sodium tetradecyl sulfate is primarily metabolized in the liver via sulfation and glucuronidation, with involvement of hepatic enzymes such as sulfotransferases and UDP-glucuronosyltransferases (UGTs).
Renal excretion of unchanged drug accounts for approximately 95% of elimination; fecal excretion is minimal (<5%).
Primarily renal; <1% recovered as unchanged drug in urine; majority eliminated as metabolites via bile into feces
Approximately 85% bound to serum albumin.
>90% bound to plasma proteins, primarily albumin
Volume of distribution is about 0.6 L/kg, indicating distribution into total body water.
0.15-0.3 L/kg; reflects limited distribution primarily to plasma and interstitial space
Oral bioavailability is approximately 80% (range 75–85%) under fasting conditions; food may reduce absorption.
Not applicable; administered via intradermal, intravenous, or endoscopic injection; not intended for oral administration
Contraindicated in patients with estimated creatinine clearance (Cr Cl) <30 m L/min. No dose adjustment required for Cr Cl ≥30 m L/min.
No specific dose adjustment provided in labeling; not studied in renal impairment; use caution in severe impairment.
Not recommended in patients with severe hepatic impairment (Child-Pugh Class C). No dose adjustment required for mild (Child-Pugh Class A) or moderate (Child-Pugh Class B) hepatic impairment.
No specific dose adjustment provided in labeling; caution in Child-Pugh class C due to potential for acute hepatic necrosis.
For adolescents aged ≥12 years and weighing ≥35 kg, administer one tablet (50/200/25 mg) orally once daily. Safety and efficacy not established in pediatric patients <12 years or <35 kg.
Safety and efficacy not established in pediatric patients (age <18 years).

No specific dose adjustment required; consider comorbidities and overall health status.
No FDA boxed warning reported.
Sotradecol injection is contraindicated for the treatment of patients with underlying arterial disease or with known allergy to the drug. Severe adverse reactions including anaphylaxis, pulmonary embolism, and tissue necrosis have been reported.
Differentiation syndrome, which may be life-threatening or fatal; if suspected, initiate corticosteroids and hemodynamic monitoring.,QTc interval prolongation; monitor electrolytes and electrocardiograms.,Embryo-fetal toxicity.
Anaphylactic reactions; arterial injection causing tissue necrosis; pulmonary embolism; allergy to the drug; use with caution in patients with thrombophlebitis, hypercoagulable states, or chronic obstructive pulmonary disease; avoid extravasation.
None reported.
Known allergy to sodium tetradecyl sulfate; acute thrombophlebitis; severe chronic venous insufficiency; arterial disease; uncontrolled diabetes mellitus; sepsis; pregnancy; breastfeeding; incompetent perforating veins.
Avoid grapefruit, grapefruit juice, Seville oranges, and starfruit as they inhibit CYP3A4 and can increase drug levels, leading to toxicity. No other known food interactions. Take with or without food, but consistent timing and fat content is recommended to maintain stable exposure.
No specific food interactions are known. Patients should maintain adequate hydration and avoid excessive alcohol intake, which may increase the risk of bleeding or thrombosis. No dietary restrictions are required.
BYQLOVI (bictegravir/emtricitabine/tenofovir alafenamide) is contraindicated in pregnancy due to risk of neural tube defects (NTDs) observed with dolutegravir-containing regimens in first trimester exposure. In animal studies, no evidence of teratogenicity at clinically relevant exposures. Human data: insufficient for risk assessment; case reports of NTDs with bictegravir insufficient to rule out. First trimester: potential for NTDs, avoid unless benefit outweighs risk. Second/third trimester: limited data, no specific fetal risks identified, but use alternative if possible.
FDA Pregnancy Category C. No adequate human studies; animal studies show fetal harm. Use only if benefit outweighs risk. First trimester: potential teratogenicity. Second/third trimester: risk of fetal bradycardia, arrhythmias, or death due to systemic absorption if injected near cervix.
Breastfeeding not recommended during BYQLOVI therapy due to potential for HIV-1 transmission via breast milk and unknown effects in infants. Bictegravir excretion into human milk unknown; emtricitabine: M/P ratio ~0.6; tenofovir alafenamide: M/P ratio ~0.3 (tenofovir). Limited data: low levels may be excreted. HIV-positive mothers should not breastfeed to avoid transmission.
Unknown excretion in human milk. Due to low systemic absorption after local injection, risk to breastfed infant is likely low. Caution recommended; M/P ratio not established.
No specific dosing adjustments recommended during pregnancy due to limited data. Pharmacokinetic studies in pregnancy are lacking. Bictegravir AUC may decrease in second and third trimester; clinical relevance unknown. Consider alternative antiretroviral regimens with established safety data in pregnancy (e.g., dolutegravir plus emtricitabine/tenofovir disoproxil fumarate).
No dose adjustment required; however, use only when clearly needed. Systemic absorption is minimal after local injection, and pharmacokinetic changes in pregnancy are unlikely to alter efficacy or safety.
BYQLOVI (bruton tyrosine kinase inhibitor) is indicated for chronic lymphocytic leukemia (CLL) and Waldenström macroglobulinemia. Monitor for atrial fibrillation, hypertension, and bleeding risk. Administer with a full glass of water and do not crush or open capsules. Dose reduction may be needed with strong CYP3A4 inhibitors. Avoid concurrent use with warfarin or other anticoagulants if possible.
Sotradecol (sodium tetradecyl sulfate) is a sclerosing agent used for the treatment of varicose veins. Administer via direct injection into the vein using a fine needle; avoid extravasation as it causes tissue necrosis. Perform a test dose (0.5 m L) to assess for hypersensitivity. Compression stockings should be worn for 1-3 weeks post-injection. Do not exceed 10 m L per session; maximum total dose per session is 10 m L of 1% or 2 m L of 3% solution. Use caution in patients with arterial disease, recent thrombosis, or known hypersensitivity. Delayed skin pigmentation may occur. Allergic reactions, including anaphylaxis, have been reported.
Take exactly as prescribed, with a full glass of water.,Do not open, break, or chew the capsules; swallow whole.,Avoid grapefruit, grapefruit juice, Seville oranges, and starfruit while on this medication.,Report any signs of bleeding (e.g., unusual bruising, black stools) or irregular heartbeat immediately.,Avoid activities that may cause injury due to increased bleeding risk.,Use effective contraception during treatment and for at least 1 month after the last dose.
This medication is injected directly into your varicose veins to cause them to collapse and fade.,You may experience a burning sensation at the injection site, which is normal.,Wear compression stockings as directed, typically for 1-3 weeks after treatment.,Avoid strenuous exercise and prolonged standing for 24-48 hours after injection.,Contact your doctor if you develop severe pain, swelling, redness, or skin ulcers at the injection site.,Notify your doctor if you have a history of blood clots, allergies, or are pregnant or breastfeeding.
