The drugs can be given through the cannula as an injection or injected into a bag to dilute them. Your treatment is often given through a pump so that your nurse can control how much of the drug you get over a set period of time.
You may feel some discomfort, pain, swelling, burning or a change in sensation around the cannula area while the drug is being given. This may be due to a small leakage of the drug into your tissues. This doesn’t happen often, but if it does, let your nurse or doctor know straight away.
