Zolpidem (Ambien) is a medication that helps you fall asleep faster. It is for short-term use only.
Paxlovid treats mild to moderate COVID-19 in adults. You must be at high risk of your illness becoming severe. This includes needing to go to the hospital or possibly dying from COVID-19. Paxlovid is not for preventing COVID-19 before or after exposure.
Zolpidem is used to treat insomnia when you have trouble falling asleep. It can help you fall asleep faster. Studies have shown it can decrease the time it takes to fall asleep for up to 35 days.
Paxlovid contains two medicines, nirmatrelvir and ritonavir. Nirmatrelvir stops the virus from multiplying in your body. Ritonavir helps nirmatrelvir stay in your body longer so it can work better.
Zolpidem affects a chemical in your brain called gamma-aminobutyric acid (GABA). GABA helps to slow down brain activity. By affecting GABA, zolpidem helps you to feel sleepy.

Paxlovid can interact with many other medicines, causing serious or life-threatening problems. Before taking Paxlovid, tell your doctor about all the medicines you take. Your doctor may need to adjust the dose of your other medicines or monitor you more closely.
Zolpidem can cause complex sleep behaviors like sleepwalking, sleep driving, and doing other activities while not fully awake. Some of these events can cause serious injuries or even death. Stop taking zolpidem right away if you experience any of these behaviors.
There is not enough information about nirmatrelvir's safety during pregnancy. Studies on ritonavir in pregnant women have not shown an increased risk of birth defects. Talk to your doctor about the risks and benefits of taking Paxlovid if you are pregnant or breastfeeding.
Taking zolpidem late in pregnancy may cause breathing problems and sleepiness in the newborn. If you are breastfeeding, pump and discard breast milk during treatment and for 23 hours after taking zolpidem.
