2 Major 1 pair checked

2 interactions

Pulmicort-F Budesonide + Formoterol Fumarate Ritonavir

Major

Ritonavir strongly slows how the body clears the steroid in Budesonide + Formoterol Fumarate. The steroid can build up and act more strongly throughout the body.

What should I do?

These medicines can affect each other in a serious way. Do not start taking them together unless your doctor has said it is OK. If you already take both, do not stop either one on your own: speak to your doctor or pharmacist soon.

What to do: Do not take these together unless your doctor has told you to.

Pulmicort-F contains Budesonide Ritonavir

Major

Ritonavir strongly inhibits CYP3A4, greatly raising systemic budesonide levels and causing Cushing's syndrome and adrenal suppression.

What should I do?

What to do: Avoid combination; consider an alternative corticosteroid such as beclomethasone if long-term therapy is needed.

What do Major, Moderate and Minor mean?

Major

The combination can cause serious harm or stop a medicine from working. Usually avoided, or only used with close medical supervision.

Moderate

The combination may need care: a different dose, taking them at different times, or extra check-ups.

Minor

Little or no effect is expected. Usually nothing needs to change.

Duplicate

Two of your medicines contain the same ingredient, which can add up to a double dose.
