Benzodiazepines Clinical Impact Increased exposure to midazolam or other benzodiazepines metabolized via CYP3A4 (alprazolam, triazolam) may increase the risk of adverse reactions [see Clinical Pharmacology ( 12.3 )].

Xanax
Emend
Alprazolam (Xanax) is a medication that can help you with anxiety and panic disorders. It belongs to a class of drugs called benzodiazepines, which work by slowing down activity in the brain.
Aprepitant (Emend) is a medicine that helps prevent nausea and vomiting. It belongs to a class of drugs called NK1 receptor antagonists.
Alprazolam is used to treat generalized anxiety disorder (GAD) and panic disorder (PD) in adults. GAD involves excessive worry and tension, while PD causes sudden and intense episodes of fear. This medicine can help reduce these symptoms.
Aprepitant is used to prevent nausea and vomiting caused by chemotherapy. It can be used for both strong and moderate chemotherapy treatments. It is also used to prevent nausea and vomiting after surgery in adults.
Alprazolam works by affecting certain chemicals in your brain called neurotransmitters. It enhances the effects of a neurotransmitter called GABA, which helps to calm your nerves. This can reduce feelings of anxiety and panic.
Aprepitant blocks a substance in your body called substance P. Substance P can trigger nausea and vomiting. By blocking it, aprepitant helps reduce these side effects.

Alprazolam can be habit-forming, leading to abuse, misuse, and addiction, which can result in overdose or death. Taking alprazolam with opioid pain medicines can cause severe sleepiness, breathing problems, coma, and death. Suddenly stopping alprazolam can cause life-threatening withdrawal symptoms. Talk to your doctor about how to safely stop taking it.
Aprepitant can interact with other medicines. It can affect how well warfarin (a blood thinner) and hormonal birth control work. If you take warfarin, your doctor will check your blood. If you use hormonal birth control, use a backup method while taking aprepitant and for 28 days after your last dose.
Taking alprazolam late in pregnancy can cause sedation or withdrawal symptoms in the newborn. Breastfeeding is not recommended while taking alprazolam because it can cause sedation and feeding problems in the baby.
There is not enough information about the safety of aprepitant during pregnancy. Talk to your doctor if you are pregnant or plan to become pregnant. It is not known if aprepitant passes into breast milk, so discuss breastfeeding with your doctor.

How to Read This alprazolam vs aprepitant Comparison
alprazolam is classified in the Benzodiazepine drug class, while aprepitant sits within the NK1 Receptor Antagonist (Antiemetic) class. Drugs from different classes work through distinct mechanisms, so a head-to-head comparison illustrates trade-offs rather than equivalence. Both drugs are prescription-only, so a licensed provider must authorize use.
Adverse event totals above are pulled from the FDA's Adverse Event Reporting System (FAERS). For these top-ranked reactions alone, alprazolam has 55,824 submissions while aprepitant has 8,556. Those figures reflect cumulative reporting volume, not per-patient risk, so older, widely dispensed drugs typically look worse on count alone. These two drugs have a known moderate interaction flagged in FDA labeling, attributed to aprepitant slows down how fast your body processes alprazolam, which causes the drug to build up in your blood. this can make you feel much more sleepy or dizzy than usual.. Serious warnings, pregnancy guidance, and contraindications can differ even when indications overlap.
A table cannot substitute for clinical judgment. Effectiveness, tolerability, drug-drug interactions with your other medications, kidney and liver function, pregnancy status, insurance formulary, and price all feed into a decision that only a licensed prescriber can make responsibly. Data here is sourced from FDA Structured Product Labels (SPL) and FAERS, both of which update as manufacturers and clinicians submit new information.
