Clinician-reviewed, head-to-head comparison of mechanism, dosing, pharmacokinetics, and safety profiles.
Last clinically reviewed: July 2026 · OpiCalc Medical Review Team
Dehydrated alcohol (ethanol) causes tissue necrosis by protein denaturation and cellular dehydration, leading to vascular thrombosis and ischemic infarction. It ablates nerve tissue by extracting lipids and precipitating proteins.
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.
FDA-approved for adjunctive therapy in the treatment of cystic thyroid nodules,Off-label: Neurolysis for celiac plexus block in pancreatic cancer pain,Off-label: Ablation of hepatocellular carcinoma,Off-label: Sclerotherapy for esophageal varices
Treatment of relapsed or refractory acute leukemia with a lysine methyltransferase 2A (KMT2A) gene translocation in adults and pediatric patients 1 year and older
Intravenous administration: 0.1-1 m L of sterile dehydrated alcohol (100% ethanol) injected directly into cystic lesions or tumors under imaging guidance. Maximum volume per injection: 1 m L, repeated up to 3 times per session depending on lesion size.
BYQLOVI (bictegravir/emtricitabine/tenofovir alafenamide) is administered orally as a single tablet (50/200/25 mg) once daily with or without food.
2-4 hours in most individuals at zero-order kinetics; terminal half-life is concentration-dependent due to saturation of alcohol dehydrogenase. Clinically, elimination rate is constant at 15-20 mg/d L/hour in non-tolerant individuals.
Terminal elimination half-life is approximately 12 hours (range 10–14 hours) in patients with normal renal function; prolonged in renal impairment.
Primarily hepatic via alcohol dehydrogenase (ADH) and aldehyde dehydrogenase (ALDH); minor metabolism via CYP2E1 at high concentrations.
Primarily metabolized by CYP3A4 and CYP2D6.
Ethanol is primarily eliminated by hepatic metabolism (90-98%) via alcohol dehydrogenase and aldehyde dehydrogenase, with 2-10% excreted unchanged in urine, breath, and sweat. Renal elimination is minor and variable.
Renal excretion of unchanged drug accounts for approximately 95% of elimination; fecal excretion is minimal (<5%).
Negligible (<5%); no specific binding proteins.
Approximately 85% bound to serum albumin.
0.5-0.7 L/kg, approximating total body water. Higher in females due to lower lean body mass.
Volume of distribution is about 0.6 L/kg, indicating distribution into total body water.
Oral: ~80-100% due to rapid absorption from stomach and small intestine; IV: 100%.
Oral bioavailability is approximately 80% (range 75–85%) under fasting conditions; food may reduce absorption.
No dosage adjustment required for renal impairment.
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 Child-Pugh-based adjustments; use with caution in severe hepatic dysfunction due to potential accumulation.
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.
Not recommended for use in pediatric patients due to lack of safety and efficacy data.
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.
No specific dose adjustment; use with caution due to age-related comorbidities and potential for increased sensitivity.
No specific dose adjustment recommended in elderly patients. Monitor renal function due to age-related decline.
No FDA boxed warning exists for dehydrated alcohol. However, it should only be administered by physicians experienced in injection techniques for specific indications due to risk of tissue necrosis and nerve damage.
No FDA boxed warning reported.
Risk of tissue necrosis and sloughing if extravasation occurs,Neurological injury if injected near nerves (e.g., peripheral nerve damage, paralysis),Hypotension and bradycardia during celiac plexus block,Alcohol intoxication and CNS depression if absorbed systemically,Use with caution in patients with liver disease or diabetes mellitus
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.
Hypersensitivity to ethanol or any component of the formulation,Acute infection at the injection site,Uncorrectable coagulation abnormalities,Pregnancy (relative contraindication due to fetal alcohol spectrum disorders)
None reported.
No specific food interactions. However, avoid alcohol consumption for 24 hours post-procedure due to risk of additive CNS depression.
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.
First trimester: Data limited; alcohol is a known teratogen causing fetal alcohol spectrum disorders. Increased risk of congenital anomalies (e.g., heart defects, microcephaly) with high systemic exposure. Second trimester: Continued risk for growth restriction and neurodevelopmental abnormalities. Third trimester: Risk of growth retardation, preterm birth, and neurobehavioral deficits. Avoid systemic use; local injection for nerve block or ablation has minimal systemic absorption but caution advised.
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.
Alcohol is excreted into breast milk; M/P ratio approximately 1.0. Chronic ingestion can impair infant motor development. Dehydrated alcohol for therapeutic injection likely results in negligible systemic levels; however, avoid breastfeeding immediately after procedure. Advise discarding milk for 2-3 hours post-procedure.
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.
No dose adjustment needed for localized injection; pharmacokinetics of ethanol unchanged in pregnancy. Avoid use as systemic agent; use alternative if possible.
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).
Absolute ethanol (dehydrated alcohol) is used for neurolysis in celiac plexus block for pancreatic cancer pain and for ablation of certain soft tissue lesions. Administer slowly to avoid local toxicity. Inadvertent intravascular injection can cause immediate pain and tissue necrosis. Use ultrasound or CT guidance for accurate placement. Monitor for hypotension, pain, and transient alcohol intoxication. Contraindicated in patients with bleeding disorders or local infection.
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.
