Is it safe to take Xanax and quinapril together?
No, it's not entirely safe. Xanax (alprazolam), a benzodiazepine for anxiety, and quinapril, an ACE inhibitor for high blood pressure, have a moderate drug interaction. Xanax can amplify quinapril's blood pressure-lowering effects, raising risks of excessive hypotension (low blood pressure), dizziness, fainting, or slowed breathing, especially in older adults or those with heart/kidney issues.[1][2]
What does the interaction do exactly?
Quinapril lowers blood pressure by relaxing blood vessels. Xanax adds central nervous system depression, which can intensify this drop and cause sedation or impaired coordination. Studies and databases note this as a pharmacodynamic interaction—no direct chemical reaction, but combined effects on the body.[1][3]
How serious is the risk?
Moderate risk per most sources: not a total contraindication, but requires monitoring. Symptoms include lightheadedness, fatigue, or falls. Rare severe cases involve respiratory depression if doses are high or with other sedatives/alcohol.[2][4] No major FDA warnings ban the combo, but adjustments are common.
What do doctors recommend?
Consult your doctor or pharmacist before combining. They may lower doses, monitor blood pressure, or switch meds (e.g., to a non-benzo anxiolytic). Don't stop either abruptly—Xanax withdrawal can be dangerous.[1][3]
Who faces higher risks?
- Elderly patients (more sensitive to BP drops).
- Those with liver/kidney impairment (slower drug clearance).
- People on multiple BP meds or alcohol.
Pregnant individuals should avoid both due to separate fetal risks.[2][4]
Are there safer alternatives?
For anxiety with BP meds: buspirone (non-sedating) or SSRIs like sertraline. For BP: ARBs like losartan (similar to quinapril but potentially fewer interactions). Always check personalized options via tools like Drugs.com interaction checker.[3]
