Antibiotics - Missed or extra doses 

Missed or extra doses 

Take antibiotics as directed on the packet or the patient information leaflet that comes with the medicine, or as instructed by your GP or pharmacist.

Missed dose

If you forget to take a dose of your antibiotics, take that dose as soon as you remember and then continue to take your course of antibiotics as normal.

However, if it is almost time for the next dose, skip the missed dose and continue your regular dosing schedule. Do not take a double dose to make up for a missed one.

If you have to take two doses closer together than normal, there is an increased risk of side effects.

Accidentally taking an extra dose

Accidentally taking one extra dose of your antibiotic is unlikely to cause you any serious harm.

However, it will increase your chances of experiencing side effects such as pain in your stomach, diarrhoea and feeling or being sick.

If you are worried or are experiencing severe side effects, speak to your GP or call NHS Direct on 0845 46 47.

Accidentally taking more than one extra dose

If you accidentally take more than one extra dose of your antibiotic, contact your GP or call NHS Direct on 0845 46 47 as soon as possible.
