A medicine dose is the amount of medicine taken at one time or during a specified period. Correct dosing matters because medicines are designed to produce their intended effects within particular dosing ranges. Taking too little medicine may reduce its effectiveness, while taking too much can increase the risk of unwanted effects. Dosing instructions can include the amount to take, how frequently to take it, when to take it, and how long to continue treatment. The appropriate dose may differ between individuals. Age, body size, kidney function, liver function, other medicines, and medical conditions can influence dosing decisions.
Patients should not change a prescription dose simply because they think the medicine is not working quickly enough. Some treatments require time before their effects become noticeable. Liquid medicines require particular care. Use the measuring device supplied with the product rather than an ordinary kitchen spoon.
If you miss a dose, do not automatically take twice the amount next time. Instructions for missed doses differ between medicines.
Never use another person's prescription medicine, even when symptoms appear similar.
If you are unsure about a dose, ask a pharmacist or healthcare professional rather than guessing.
Disclaimer: Dosing instructions should always come from the specific medicine label or a qualified healthcare professional.
