“b.i.d.” is an abbreviation that is commonly used on medical prescriptions, and it stands for “bis in die” in Latin, which means “twice a day” in English.
When a medication is prescribed with the instructions “b.i.d.”, it means that the medication should be taken twice a day, with approximately 12 hours between doses. For example, if a medication is prescribed as “take 1 tablet b.i.d.”, the patient should take one tablet in the morning and one tablet in the evening, approximately 12 hours apart.
It is important to follow the instructions on a prescription label carefully, including the frequency of dosing, in order to ensure the safe and effective use of medication. If a patient is unsure about how to take a medication, they should consult with their healthcare provider or pharmacist for further guidance.
