Nursing considerations
- The abbreviation AZT has also been used for another medication.



- Optimum time to start treatment depends on the CD4 cell count, plasma viral load and clinical symptoms. The aim is to start treatment before the immune system is irreversibly damaged, but early treatment should be balanced against the development of toxicity.



- Regular blood tests to monitor for anaemia and assess viral load and CD4 count are required.



Patient teaching
- This medication needs to be taken regularly on a long-term basis to remain effective.



- Ensure patients understand that this drug is not a cure for Aids but will control symptoms.



- Advise patients to notify their prescriber if they have signs of infection, such as sore throat or swollen lymph glands.



- Education regarding safe sexual activity is essential as the medication does not prevent the virus being passed on to others.



Nurses should refer to manufacturer’s summary of product characteristics and to appropriate local guidelines
