What is TDS?

TDS stands for “ter die sumendus,” Latin for “to be taken three times a day.” It is an abbreviation commonly used by healthcare professionals to indicate the dosing frequency of a medication.

By prescribing TDS, physicians ensure that patients receive the right amount of medication spread throughout the day for effective treatment. This dosing schedule is often employed when maintaining consistent drug levels in the patient’s body is essential for therapeutic success.
