Are you pregnant or trying for a baby?
If you are pregnant, think you may be pregnant, or are planning to have a baby, don't take Paxlovid. Ask your doctor for advice as Paxlovid is not recommended during pregnancy. Women should avoid becoming pregnant (eg, use contraception or abstain from sexual activity) while taking Paxlovid and for 7 days after the treatment ends.
Contraception is very important
If you are taking birth control pills, extra care is needed as Paxlovid may affect how they work. It is recommended that you don’t have sexual activity while taking Paxlovid and for 7 days after the treatment ends. Otherwise use condoms as well as your usual contraception, while taking Paxlovid and for 7 days after treatment ends. Ask your doctor or pharmacist for advice.
Are you breastfeeding?
Breastfeeding is not recommended during treatment and for 7 days after the last dose of Paxlovid. This is because it is not known if Paxlovid gets into breast milk and could be passed to the baby. Tell your healthcare provider you are breastfeeding BEFORE taking this medicine.
Possible side effects
Like all medicines, Paxlovid can cause side effects, although not everyone gets them. The side effects should pass after completing the course of treatment.

Can COVID symptoms return after treatment with Paxlovid?
Yes, for some people symptoms may return after finishing a course of Paxlovid. This is known as ‘Paxlovid rebound’.
- This is when, people get symptoms after finishing a course of Paxlovid, or have negative test results immediately after Paxlovid treatment but later test positive.
- The rebound symptoms are usually mild and get better within 3 to 5 days.
If you get Paxlovid rebound within 28 days of your symptoms or tested positive, you should stay home until you've had no symptoms for at least 24 hours.
There is no need to take another course of Paxlovid if your symptoms return within 28 days. If you develop COVID symptoms after finishing a course of Paxlovid and you're not sure what to do, call your doctor or pharmacist for advice. Read more about return of symptoms after Paxlovid treatment.
