How do I take Paxlovid (nirmatrelvir/ritonavir) exactly?
Paxlovid dosing is taken by mouth for a short course. The standard adult regimen is 300 mg nirmatrelvir plus 100 mg ritonavir together twice daily (every 12 hours) for 5 days.
What dosing schedule (morning/evening) should I follow?
Take your doses about 12 hours apart, twice daily, for 5 days total. Using fixed times (for example, morning and evening) helps keep the timing consistent.
What if I have kidney problems—does the dose change?
Yes. Paxlovid dosing depends on kidney function. People with reduced kidney function may need a lower dose or extended adjustment based on the specific level of renal impairment.
What if I have liver problems?
People with significant liver impairment may not be able to take Paxlovid as prescribed. Clinicians decide dosing and suitability based on the degree of hepatic impairment.
When should Paxlovid start after symptoms begin?
Paxlovid is meant to be started early in the course of COVID-19. Treatment timing is based on eligibility and current prescribing guidance.
Can I take Paxlovid with other medicines?
Many drug interactions are possible because ritonavir affects drug-metabolizing enzymes. Before starting, patients should review their full medication list with a clinician or pharmacist so interactions can be avoided or dose-adjusted.
What should I do if I miss a dose?
Follow your prescriber’s instructions. In general, if you miss a dose, do not double up without clinician guidance, since timing and interaction risk with other medications matter.
Are there special instructions for older adults?
Dosing and interaction checks become more important with age because kidney function changes and patients are more likely to take multiple medicines. Your clinician may adjust the dose if kidney function is reduced.
Where can I verify the official dose for my situation?
