The correct answer is option B - Drink at least eight 8-oz glasses of fluid daily
Co-trimoxazole, popularly known as Bactrim, is a combination of 2 antibiotics - sulphamethoxazole and trimethoprim. It is used to treat many bacterial infections.
A person on Co-trimoxazole should take plenty of water daily to prevent the likelihood of developing kidney stones. This will help improve urine output, which in turn will increase the rate of excretion of the drug.
It is best to take co-trimoxazole with food, but it can be taken on an empty stomach. The antacid is not known to interfere with the absorption of co-trimoxazole. Avoiding it when on co-trimoxazole therapy would not change anything.
Co-trimoxazole can cause you to be more sensitive to the sun. The patient should be advised not to start long in the sun.
