Calculate Doses For Select Drugs => CALCULATE

If you have javascript enabled on your browser, you should be able to use this handy drug calculator. If you use Netscape, you may need to refresh the page to get all the information.

DOSE IN MG: In order to determine the dose in mg, you must have an accurate weight for your guinea pig.

DOSE IN CC: (1 cc = 1 ml) In order to determine the dose in cc, you must have both the weight of your guinea pig and know the concentration of the suspension being prescribed. This calculator allows you to select a few (but not all) drug doses for common suspensions.

Because there is a range of values for drugs like enrofloxacin (baytril), don't assume the calculated dose is correct. Your vet may be using a higher or lower dose range to treat your pet, depending on what illness your guinea pig has, how serious it is, and whether or not additional antibiotics are being prescribed concurrently.

*** Read over Calculating Doses to understand the relationship between drugs in mg and drugs in suspension. If you know the weight of your guinea pig, the dose (or dosage), and the concentration of the medication in mg/cc, you can also use the calculator on the Calculating Doses page to determine the dosage (or dose in cc).

If you are unsure of how many pounds (in decimal form) your guinea pig weighs, check out the Weight Conversion Chart.

1 kilo = 1000 grams = 35.2 ounces = 2 pounds 3.2 ounces = 2.2 pounds

Convert kilos to pounds by multiplying the number of kilos by 2.2
Convert grams to kilograms by dividing the number of grams by 1000
      (move the decimal point 3 spaces to the left - i.e. 600gm = 0.6kg)
Convert pounds to kilos by dividing the number of pounds by 2.2
Convert ounces to kilos by dividing the number of ounces by 35.2

You must consult with your vet and confirm the dose before administering any medications. If you make a mistake in calculation, the results could be fatal. Your vet will ensure that the medication should be given. This calculator is available for informational purposes only.
