Can cyclophosphamide affect other medicines and treatments?
Cyclophosphamide may be prescribed alongside other drugs (for example, steroids) to treat your condition. However, some drugs can interact with cyclophosphamide, so speak to your doctor before starting any new medications and remember to mention you're on cyclophosphamide if you're treated by anyone other than your usual healthcare team.
Can I have vaccinations while I'm on cyclophosphamide?
It's recommended that people on cyclophosphamide avoid live vaccinations such as yellow fever. However, sometimes a live vaccine may be necessary (for example, rubella immunisation in women of childbearing age).
If you're offered shingles vaccination (Zostavax) it's best to have this before starting cyclophosphamide. Shingles vaccination isn't recommended for people who are already on cyclophosphamide.
Pneumococcal vaccine (which protects against the commonest cause of pneumonia) and yearly flu vaccines are safe and recommended.
