How it is given
PATENT BLUE V will be given to you in hospital or a clinic. The doctor will determine the dose that you will receive and will supervise the injection. PATENT BLUE V will be diluted with suitable fluids and then administered to you under the skin (subcutaneous route).
If you are given too much (overdose)
As you will be administered the injection under the supervision of your doctor, it is extremely unlikely that you will be given too much.
However, if you experience any side effects after being given this medicine, tell your doctor or nurse immediately.
All medicines can have side effects. Sometimes they are serious, most of the time they are not. You may need medical treatment if you get some of the side effects.
Tell your doctor if you notice any of the following:
- bluish discolouration of the skin after injection, which disappears within the following 24 or 48 hours. If you have a disease affecting your lymph nodes (obstruction of lymph flow) or blood circulation disorders, this discolouration may last longer.
- allergic reactions may also occur, such as:
– spots on the skin, redness and itching (urticaria), sudden swelling of the face and neck or other parts of the body, breathing difficulties with a cough (bronchospasm)
– very rarely, sudden fainting and an important drop in blood pressure that can be life-threatening (allergic shock).
If you experience one of these effects, contact your doctor immediately.
Tell your doctor if you notice anything else that is making you feel unwell, even if you think the problems are not connected with this medicine and are not referred to in this leaflet. Other side effects not listed above may also occur in some people.
Do not be alarmed by this list of possible side effects. You may not experience any of them.
