Zith dosage?

The Ped. prescribed a 250 mgs Z-Pack for my sin who weighs 106 pounds. Is that about right? Or is that a low dose?

The Ped. prescribed a 250 mgs Z-Pack for my sin who weighs 106 pounds. Is that about right? Or is that a low dose?

As I recall, zpacs dose 500mg on the 1st day, then 250mg/day for 4 days? Here's the reasoning: The initial higher dose saturates the tissues and zith has a long half life, so the subsequent doses maintain saturation by replacing what has been eliminated by the body in the 24 hours since last dose.

 

Here's what we're doing with my 100lb daughter: We did 500mg/day for 3 days, then 500mg every other day after that. So far that has been working well for us.

MY 120 lb., 80 lb. and 50 lb. children take Zithromax 250mg per day as a prophylactic dose. When we tried to decrease it to 125/day, symptoms creeped back. When they have been exposed to strep or have a flareup in symptoms, I bump the older kids up to 500 for a few days and the younger one up to 375 for a few days.

 

My niece and nephew both have PANDAS also. Their pediatrician, who is super conservative, puts them on Zithromax 500mg/day for 10 days when they have an active strep infection (they take Augmentin 1000mg/day as a prophylactic dose which usually keeps them from getting strep, but occasionally they require the Zithromax added in). This docotr told my sister that with an active strep infection in a person weighing 80 lb. or more, Zithromax should be given at 500 mg/day. I have searched and searched for anywhere this is actually documented and can't find it.

DS 5 has been on 1200 mg of Augmentin since IVIG 3 months ago. Still having terrible anxiety so we are going to try Zith. The Ped perscirbed 3 cc's liquid a day. DS weighs 48lb. Does that sound like the correct dose?

My 50 lb. child takes Zithromax 250/day and has been taking that dose since he weighed 45 lb.

 

Does your bottle say 100mg/5ml OR 200mg/5ml? It most likely is the latter, which means he would be takling 120mg/day. IMO, that is a low dose.

My 58 pounder is on 250mg/day (since June 08, when she was 44 pounds). I would put a 100 pounder on 500mg/day, at least for the first month or 2. You could always experiment with decreasing to 250mg/day after that.
