How do I calculate the doasage of Amoxicillin suspension 125mg/5ml if the dose ordered is 3/4 tsp Po Bid?
Given
3/4 tsp Po Bid
First convert tsp to ml using
1 tsp = 5 ml.
so 3/4 tsp = (3/4)*5 = 3.75 ml.
So the prescription calls for
3.75 ml. of a suspension 125 mg/5ml
125 mg : 5 ml
X mg : 3.75 ml
By cross multiplication, we get
X=3.75*125/5=93.75 mg (twice a day)
To calculate the dosage of Amoxicillin suspension 125mg/5ml, you need to use the following formula:
Dosage = (Dose ordered * Volume per dose) / Concentration
Where:
- Dose ordered is the prescribed amount of medication per dose.
- Volume per dose is the quantity of Amoxicillin suspension to administer per dose.
- Concentration is the strength of the Amoxicillin suspension, which is given in mg/ml.
In this case, the dose ordered is 3/4 tsp and the concentration of Amoxicillin suspension is 125mg/5ml.
First, we need to convert the volume of the dose ordered into milliliters (ml). 1 teaspoon (tsp) is approximately equal to 5 ml. So, 3/4 tsp is equal to (3/4) * 5 = 3.75 ml.
Now, substitute these values into the formula:
Dosage = (3.75 ml * 1) / 125 mg/ml
Simplify the calculation:
Dosage = 3.75 / 125
Dosage = 0.03 ml
Therefore, the dosage of Amoxicillin suspension 125mg/5ml for a dose ordered of 3/4 tsp Po Bid is 0.03 ml per dose.
