Using budesonide nasal spray with other medicines and herbal supplements

Some medicines can affect budesonide nasal spray. This may increase your chance of having side effects or change how well it works. It may mean you need to change your dose of budesonide.

Speak to a pharmacist or your doctor before starting to use it if you're taking:

• medicines used to treat HIV such as ritonavir or cobicistat
• antifungal medicines such as itraconazole
• other medicines that contain steroids such as eczema creams, asthma inhalers, steroid tablets, injections or eye drops

There's not enough information to say that complementary medicines, herbal remedies and supplements are safe to use with budesonide nasal spray. They're not tested in the same way as pharmacy and prescription medicines. They're generally not tested for the effect they have on other medicines.

Tell your doctor or pharmacist if you're taking any other medicines, including herbal remedies, vitamins or supplements.
