With this example one can compute the safe maximum dose of two medicins. The example is meant for use by Ophthalmologists. No liability can be accepted for use of this example.
The safe dose can be computed for two medicins: Chloroquine and
Hydroxychloroquine (Plaquenil). This dose should be computed based on the patients
ideal weight, which is computed from the patients height.
About 20% of the prescriptions contains errors. Therefore it would be ideal if patients would be able to check their prescriptions, and the dosages. I hope this numerical module helps.
Background information on these medicins can be found via the following links:

If the weight is not zero then the computation will be based on this, actual, weight. If the weight is left zero then the computation will be based on the 'ideal' or lean body weight instead of the actual weight. The ideal weight is computed as 0.85 (height (cm) - 100) and also displayed as a result.
If the actual weight is less than the ideal weight, then the actual weight should be used.
Otherwise using the ideal weight is preferred above using the actual weight, in particular for obese patients.
