Introduction While dispensing cough syrup to a patient (I counselled him to take 10 ml 3 times a day), the patient questioned if it was equivalent to a tablespoon. Teaspoon and Tablespoon The conversion from teaspoon or tablespoon to millilitres is as below: 1 teaspoon = 5 ml 1 tablespoon = 15 ml However, a household silverware or tableware spoon are not uniformly sized, so they should not be used for measuring medication. A typical household teaspoon can hold between 3 and 7 millilitres depending on its size. Syringe To ensure accuracy, a syringe should ideally be used when dosing liquid medications. The smallest syringe that can hold the desired amount of volume should be used to maximize accuracy. It is important to avoid drawing up to the maximum capacity of the syringe to prevent the plunger from dislodging. NOTE: Dosing cups that come with the liquid medications are fine to use. However, errors have occurred when dose cups intended for one product was used with another wit...

Introduction Aseptic technique is a skill in the compounding of sterile preparations that is independent of equipment [e.g. primary engineering control (PEC) and secondary engineering controls (i.e. cleanroom) ] and environment. Proper use of Laminar Airflow Workbench (LAFW) An LAFW should operate continuously when in use. Before use, all interior working surfaces of the LAFW must be cleaned from the cleanest part of the LAFW to dirtiest part with sterile 70% isopropyl alcohol (IPA) or another disinfecting agent and a clean, nonshedding, lint-free wipe. The LAFW should be cleaned and disinfected frequently, including at the beginning of the wok shift, before the start of each batch, every 30 minutes during continuous compounding periods, when there are spills, and when there is known or suspected contamination from a lapse in the aseptic technique process. Nothing should touch the HEPA filter. Nothing should disrupt or block the unidirectional airflow between the high-efficiency pa...
