Warnings and precautions
Talk to your doctor or hospital pharmacist or nurse before using Vancomycin if:
- If you are allergic to vancomycin or any of the other ingredients of this medicine
- You suffered a previous allergic reaction to teicoplanin because this could mean you are also allergic to vancomycin.
- You have a hearing disorder; especially if you are elderly (you may need hearing tests during treatment).
- You have kidney disorder (you will need to have your blood and kidneys tested during treatment).
- You are receiving vancomycin by infusion for the treatment of the diarrhoea associated to Clostridium difficile infection instead of orally.
Talk to your doctor or hospital pharmacist or nurse during treatment with Vancomycin if:
- You are receiving vancomycin for a long time (you may need to have your blood, hepatic and kidneys tested during treatment).
- You develop any skin reaction during the treatment.
- You develop severe or prolonged diarrhoea during or after using vancomycin, consult your doctor immediately. This may be a sign of bowel inflammation (pseudomembranous colitis) which can occur following treatment with antibiotics.
- Special care will also be taken if you are elderly or you are due to have a general anaesthetic.
- Special care is needed if you are taking/using other medicines as some could interact with vancomycin, for example: other antibiotics that can affect your kidneys e.g. streptomycin, neomycin, gentamicin, kanamycin, amikacin, tobramycin, polymyxin B and colistin, water tablets e.g. ethacrynic acid and frusemide, cholestyramine (a medicine used to treat high levels of fat in the blood or diarrhoea in inflammatory diseases of the gut)
- Vancomycin will be used with particular care in premature infants and young infants, because their kidneys are not fully developed and they may accumulare vancomycin in the blood. This age group may need blood tests for controlling vancomycin levels in blood.
- Concomitant administration of vancomycin and anaesthetic agents has been associated with skin redness (erythema) and allergic reactions in children.
- Similarly, concomitant use with other medicines such as aminoglycoside antibiotics, nonsteroidal anti-inflammatory agents (NSAIDs, e.g., ibuprofen) or amphotericin B (medicine for fungal infection) can increase the risk of kidney damage and therefore more frequent blood and renal test may be necessary.
Take special care with Vancomycin Hydrochloride Powder for Concentrate for Infusion

- If you have hearing difficulties

Preparation of Solution:
For single use.
At the time of use, add 10 ml of sterile Water for Injections BP to a 500 mg vial of Vancomycin Hydrochloride 500 mg Powder for Concentrate for Infusion. Similarly, add 20 ml of sterile Water for Injections BP to a 1 g vial of Vancomycin Hydrochloride 1 g Powder for Concentrate for Infusion. Vials reconstituted in this manner will give a solution of 50 mg/ml. Further dilution is required depending on method of administration:
Intermittent infusion (the preferred method of administration):
Reconstituted solutions containing 500 mg vancomycin must be diluted with at least 100 ml diluent. Reconstituted solutions containing 1 g vancomycin must be diluted with at least 200 ml diluent.
Sodium Chloride Intravenous Infusion B.P. or 5% Dextrose Intravenous Infusion B.P. are suitable diluents. The desired dose should be administered by intravenous infusion over a period of at least 60 minutes. If administered over a shorter period of time or in higher concentrations, there is a possibility of inducing marked hypotension in addition to thrombophlebitis. Rapid administration may also produce flushing and a transient rash over the neck and shoulders.
Continuous infusion (should only be used when intermittent infusion not feasible):
1 g or 2 g of vancomycin may be added to a sufficiently large volume of Sodium Chloride Intravenous Infusion B.P. or 5% Dextrose Intravenous Infusion B.P. to permit the desired dose to be infused over twenty-four hours.
