How much amoxicillin 400mg should I give me son that weights 41 pounds and is 6 for strep?

How much amoxicillin 400mg should I give me son that weights 41 pounds and is 6 for strep?

Dose for strep: You can give him roughly 25 mg/kg per dose, twice daily dosing for 10 days. If you have the 400 mg/5 ml suspension of amoxicillin, you could give him 6 ml (=480 mg) twice daily for 10 days. Make sure to give him the full 10 day course even if he is feeling well after a couple of days. ...Read more

My 29lb daughter was given a dosage of 4ml twice a day of liquid amoxicillin (400mg/5ml). Does it correct? Not overdose ? Thank You.

 My 29lb daughter was given a dosage of 4ml twice a day of liquid amoxicillin (400mg/5ml). Does it correct? Not overdose ? Thank You.

Depends: The dosing for this med is based on both patient weight and what you are treating. For some respiratory or urinary infections the dosage of 50mg/kg/d would be expected.For an otitis media, 90mg/kg could be considered proper. Your dosage is at the lower end of normal for some issues and low for others. ...Read more

My 42lb son was given a dosage of 6mls twice a day of liquid amoxicillin (400mg/5ml) for strep. Does this seem right? Worried about overdose. Thanks.

Yes: The dose your son was given is correct. Make sure he is staying hydrated and don't forget to get him a new tooth brush in a few days (his old one is likely teeming with strep). Hope he starts feeling better really soon! ...Read more

No, that dose is: fine. There is a dosing range depending on the child's weight, which is 40-80 mg/kg/day. He is 14.5 kg, so this dose is 55mg/kg/day, which is perfectly fine. ...Read more

My 70lb son was given a dosage of 18. 5mls twice a day of liquid amoxicillin (400mg/5ml) for strep. Does this seem right? Worried about overdose. Than

Seems high: That dose is about 1400 mg per dose which translates into 90 mg/kg per day. this is on the high end of treating resistant strep pneumo for otitis media. Definitely not appropriate dose for strep or pneumonia ...Read more

My son who is 2 yrs old and around 35lbs was prescribed amoxicillin 400mg/5ml 10ml twice a day does that sound accurate? Worried it might be too much?

My son who is 2 yrs old and around 35lbs was prescribed amoxicillin 400mg/5ml 10ml twice a day does that sound accurate? Worried it might be too much?

Not really: The dosing on this and most antibiotics depends on weight AND what you are treating.If it were a UTI or bronchitis where the abx gets into the germ areas easily we can use less, if ear infection we have to use more to get in.The dosing recommended for ear infections is 80-90 mg/kg/day.This would calculate to 716 mg twice a day or 1.78 tsp. Most just round up to 2 because the extra is not a problem ...Read more
