Patient told to stop blood pressure medication. Calling because first he took the booster shot COVID vaccine and tested negative. This morning he tested positive and wants to know if he can take the COVID vaccine and take Paxlovid at the same time. Had all the boosters and got the newest one yesterday at 3 o'clock. Was exposed to COVID by a family member. Tested negative via a home test yesterday. This morning he tested positive. Contacted his HCP and the HCP prescribed him Paxlovid. Wondering since he just had the booster yesterday, is the Paxlovid going to overwhelm his system or will he get hurt or is there a contraindication. Type 1 diabetic for 50 years, does take insulin. Takes medicine for high blood pressure which his HCP told him to stop for 5 days. Pharmacist doesn't know if it was alright to take Paxlovid after the booster.
