I tested positive for Covid 8 days ago. The Doctor prescribed amox-clav 500mg a day for 7 days and zinc. I tested day before yesterday and my INR has dropped to 1.5. Today it was only 1.6. Increased my dose from 12.5 to 15 tonight. Last week it was 2.3 and has been steady at 2.3 - 2.5 before this Covid infection. I thought antibiotics would enhance the anticoagulation if anything. I not comfortable with 1.6 at all. I’m calling the doctor tomorrow about stopping the antibiotic and see if my goes back to normal. I thought I read somewhere that Covid was causing blood clots in some people. Has anyone experienced this while having Covid infection?

Increase your dose by 50% once (I see you did a little less, that'll do) and then resume your previous dose. Test again in 3 days and follow up here. @ mention me so I don't miss it.

Antibiotics will commonly cause a dose change requirement, which will cease when you cease the course. It's common with these things, so always test a couple if days after you commence a new medication.

Always

My INR also dropped to 1.7 from 2.5 range during Covid and I had to bump my dose to get back to 2.5 range . It took couple of days for me to get INR up .

Mine was complete opposite.
INR went to 4.8 two days into paxlovid. Then after stopping a dose of jantovin, went higher. It’s been out of range high for 3 weeks now at 3.7, even though I’ve gone to 1/2 tab one day per week. Now I’ve been advised to take 1/2 tab twice a week, and full tab 5 days.

It can raise the INR up very high and very low with the use of certain antibiotics. Be careful on the dosing. Hope you got to go into the Doctor's office. Hope you all feel better soon.

They made you feel like a yoyo with the antibiotics. My mother had problems with infections due to her RA years ago and she said all the switching on the antibiotics made her feel like a Guinea pig.

I didn’t take antibiotics, only started Paxlovid the day I tested positive. That 1st day I had 103.7 fever. I took rapid release acetaminophen and it went down to 102.1.
I felt pretty bad those first days. The Paxlovid has a horrible after taste that made me nauseous. I ate soup and crackers mostly. I lost 4 lbs.
I used my pulse oximeter often but luckily my oxygen level stayed in 90’s.
I was afraid of COVID because of my multiple surgeries and lingering pre existing issues. I felt so tired long after the 10 days of isolation. My cough still hasn’t gone away. But this week I finally didn’t need a nap every day, so things are looking up!
