Will Paxlovid interfere with my birth control?

Ritonavir, a component of Paxlovid, may reduce the effectiveness of combined hormonal contraceptives (estrogen + progesterone), so you should use another form of contraception when taking Paxlovid. You should tell your healthcare provider about all of the prescriptions, over-the-counter medications, and supplements you take before deciding whether to take Paxlovid.
