Drinking plenty of water is an important precaution for a prescription of Bactrim, which is a combination antibiotic containing sulfamethoxazole and trimethoprim. This precaution is particularly relevant because Bactrim can lead to the formation of crystals in the urine, which may result in kidney damage or other complications like renal failure if not properly hydrated. Adequate hydration helps dilute the urine and reduce the risk of crystallization, ensuring safer elimination of the drug from the body.

The other options relate to aspects that do not reflect the correct handling or effects related to Bactrim. For instance, Bactrim is available in both oral and injectable forms, it does not need refrigeration, and while it may cause some side effects, extreme drowsiness is not typically associated with it in comparison to other medications. Thus, the emphasis on hydration highlights a key safety measure when taking this medication.
