Meds that PATIENTS must dilute or reconstitute (PEG bowel preps, cholestyramine, liquid potassium chloride, etc) will cause a stir.
These types of meds are prone to mishaps...since they rely on the patient to properly mix the med in water or another liquid.
Take steps to prevent errors in reconstitution. Mistakes can lead to over- or underdosing, side effects, etc.
Ask your pharmacist about including additional directions on the Rx label if a patient will need to mix the med before use.
For example, labelling Nexium (esomeprazole) 10 mg granules for oral suspension with the sig "Mix one sachet with one tablespoonful (15 mL) of water, then drink once daily"...instead of "Take one sachet daily"...may avoid misunderstandings.
Apply a "dilute before administration" or "mix with water" auxiliary label...and consider highlighting the instructions...as added reminders for patients and caregivers.
But don't place labels over instructions on the original med container. The package may list other important tips for mixing.
Send patients to the pharmacist for counselling on how to dilute or reconstitute their Rx. If a special diluent is needed, make sure the patient has it...and knows how to use it.
For instance, some nebulizer solutions (salbutamol 0.5%, etc) need to be diluted with sterile 0.9% saline. Using regular water could lead to contamination or make the patient's breathing worse.
Ensure that other meds...such as antibiotic suspensions (cefprozil, cefixime, etc) and BenzaClin (benzoyl peroxide/clindamycin)...are properly mixed BEFORE they leave the pharmacy.
