How long should it take for Levoflaxin to kick in for Serratia marcescens and Stenotrophomonas maltophilia In the sinuses? I've been taking it 4 days.
5 days.: Sinus infections are tough to treat because the blood supply to the sinuses is poor (the arteries are small). It may take 5 days of antibiotics before you start to see some change in the color of the mucus. If no change at all, call your doc If you are only 50% better by the time you finish the antibiotic, it means it's working, but you need a second course to kill all the rest of the germs. ...Read more

Could plaquenil (hydroxychloroquine) for UCTD make me susceptible to Serratia marcescens and Stenotrophomonas maltophilia in two sinus cultures?

I would guess you might have had recurrent sinusitis (or other infections) where you were treated with abx. ...Read more

I have been using a waterpik unit that i discovered has a pink mold (serratia marcescens?) in the tubing , concerned that i may get a blood infection from using this "infected water" around my gums.
Throw it out!: It is very hard to be sure the tubing is cleaned out properly. Best to discard the unit and buy a new one. You could try to contact the company to see if you can easily purchase and install new tubing. An excellent water pik is under $60. I would feel more comfortable with a new unit since you do not know what else has been contaminated. Be sure to change your tips every 3-4 months! ...Read moreSee 2 more doctor answers
