What Is a Course of Treatment? Finish the Course Explained
Course of treatment · say it: KORS uv TREET-mentAlso written: treatment course, full course, course of antibiotics, course of therapy
Short answer
A course of treatment is the full planned period of taking a medicine, such as a set number of days of antibiotics.
What it means
A course of treatment means the whole planned length of a treatment, from the first dose to the last. For example, a doctor may prescribe a 7-day course of antibiotics, a short course of steroid tablets, or several cycles of chemotherapy. The length is chosen to treat the problem fully while limiting side effects.
Labels and leaflets often say 'complete the full course' or 'take for the full prescribed time', especially for antibiotics and antivirals. The aim is to clear the infection properly, even if you feel better early. Other leaflets explain what to do if a course is interrupted, or warn not to repeat a course without seeing a doctor.
Advice about finishing a course can differ by medicine and situation, and some guidance now favours shorter courses for certain infections. The course on your prescription is the one to follow unless your doctor or pharmacist tells you otherwise. Maintenance therapy is different: it is ongoing treatment without a fixed end.
