Taking PAXLOVID with these medicines may cause serious or life-threatening side effects or affect how PAXLOVID works. These are not the only medicines that may cause serious side effects if taken with PAXLOVID. PAXLOVID may increase or decrease the levels of multiple other medicines. It is very important to tell your healthcare provider about all medicines you are taking because additional laboratory tests or changes in the dose of your other medicines may be necessary while you are taking PAXLOVID. Your healthcare provider may also tell you about specific symptoms to watch out for that may indicate that you need to stop or decrease the dose of some of your other medicines.

Possible side effects of PAXLOVID are:

Allergic Reactions. Allergic reactions, including severe allergic reactions (known as ‘anaphylaxis’), can happen in people taking PAXLOVID, even after only 1 dose. Stop taking PAXLOVID and call your healthcare provider right away if you get any of the following symptoms of an allergic reaction:
- hives
- trouble swallowing or breathing
- swelling of the mouth, lips, or face
- hoarseness
- throat tightness
- skin rash
Liver Problems. Tell your healthcare provider right away if you have any symptoms of liver problems (loss of appetite, yellowing of your skin and the whites of eyes (jaundice), dark-colored urine, pale-colored stools and itchy skin, or stomach area (abdominal) pain.)
Resistance to HIV Medicines. If you have untreated HIV infection, PAXLOVID may lead to some HIV medicines not working as well in the future.
Other possible side effects include:
- altered sense of taste
- diarrhea
- high blood pressure
- muscle aches
- abdominal pain
- nausea
- feeling generally unwell

These are not all the possible side effects of PAXLOVID. Serious and unexpected side effects may happen. PAXLOVID is still being studied, so it is possible that all risks are not known at this time.

There is no experience treating pregnant women or breastfeeding mothers with PAXLOVID. For a mother and unborn baby, the benefit of taking PAXLOVID may be greater than the risk from the treatment. It is recommended that you use effective barrier contraception or do not have sexual activity while taking PAXLOVID. If you are pregnant or breastfeeding, discuss your options and specific situation with your healthcare provider.

Contact your healthcare provider if you have any side effects that bother you or do not go away. Report side effects or problems with the appearance or packaging of PAXLOVID to FDA MedWatch at www.fda.gov/medwatch or call 1-800-FDA-10881-800-FDA-1088, or you can report side effects to Pfizer Inc. at www.pfizersafetyreporting.com, by fax at 1-866-635-83371-866-635-8337, or by calling 1-800-438-19851-800-438-1985.
