Important topics to cover with a healthcare professional
Talk to a healthcare professional about all the patient's medical conditions and review recent medical records together
This will help a healthcare professional determine if PAXLOVID is an option, if a different dose is needed, or if they need to stop or change the dose of any other medicines being taken.
Help prepare for this discussion by knowing if the patient:
-
Is allergic to nirmatrelvir, ritonavir, or any of the other ingredients in PAXLOVID
-
Has liver or kidney problems, including hepatitis (bring the patient's latest lab results, if possible)
-
Has Human Immunodeficiency Virus 1 (HIV-1) infection. PAXLOVID may lead to some HIV-1 medicines not working as well in the future
-
Is pregnant, plans to become pregnant, is breastfeeding, or plans to breastfeed. It is not known if PAXLOVID is safe to take during pregnancy or while breastfeeding, so be sure to discuss this with a healthcare professional
-
Is taking a hormonal birth control medicine. PAXLOVID can affect how some birth controls work, so be sure to ask a healthcare professional if the patient needs to use a different or an additional form of contraception
It is very important to have a list of all the medicines that the patient is taking, including over-the-counter and prescription medicines, vitamins, and herbal supplements
-
A healthcare professional can advise if it's safe for the patient to take PAXLOVID with other medicines
-
You or the patient can ask a healthcare professional or pharmacist for a list of medicines that interact with PAXLOVID
-
The patient should not start taking a new medicine without telling a healthcare professional
Some medications cannot be taken with PAXLOVID

-
It is very important to tell a healthcare professional about all the medicines the patient is taking because additional laboratory tests or changes in the dose of the other medicines may be necessary during treatment with PAXLOVID
-
A healthcare professional may also tell you about specific symptoms to watch out for that may indicate that the patient needs to stop or decrease the dose of some of the other medicines
-
