You Need to Go Back to School!

There is a doctor who does not know what is Bactrim and just prescribe it for a patient. Bactrim is a combination antibiotic containing trimethoprim and sulfamethoxazole (both are antibiotics). Thing is the commercial adult tablet contains 80mg of trimethoprim and 400mg of sulfamethoxazole. There are 2 ways to prescribe this drug:
1. Bactrim 480mg BD x 1/52 (meaning 480mg 2 times a for 1 week) OR
2. Bactrim 80mg (TMP) BD x 1/52 (TMP is the short form for trimethoprim)

Either way at pharmacy side we would know immediately that the doctor wants to give 1 adult tablet twice a day. However, the stupid doctor prescribed it as Bactrim 120mg BD, and when I called up to clarify if he is referring to the TMP component, he asked me what is trimethoprim! Naturally I was shocked as it meant the doctor does not know anything about the drug that he prescribed for the patient.

I went into a detailed explanation of what components can be found in Bactrim and after the explanation he still does not get the fact that Bactrim contains 2 antibiotics. Really feel like strangling the doctor. Best is to bludgeon him and make him forget he is a doctor so he will not do more harm to patients.
