To rewrite the prescription using the 125 mg/5 ml suspension, we need to ensure that the total amount of medication remains the same. Since the concentration of the 125 mg/5 ml suspension is half of the 250 mg/5 ml suspension, we need to adjust the volume accordingly.
Given:
- Original prescription: 3.5 ml of a 250 mg/5 ml cefdinir suspension twice daily for 10 days.
We'll first find the total amount of medication per dose in mg:
Original dose:
- Concentration: 250 mg/5 ml
- Volume: 3.5 ml
- Total medication per dose = (250 mg/5 ml) * (3.5 ml) = 250 * 3.5 / 5 = 175 mg
Now, we'll rewrite the prescription using the 125 mg/5 ml suspension:
Adjusted dose:
- Concentration: 125 mg/5 ml
- Total medication per dose = 175 mg
- Volume = Total medication per dose / Concentration = 175 mg / 125 mg/5 ml = (175 / 125) * 5 ml = 7 ml
So, the adjusted prescription would be to take 7 ml of the 125 mg/5 ml cefdinir suspension twice daily for 10 days.
