Summary
NSAIDs such as fenbufen can reduce the antihypertensive effect of beta blockers with regular use. They may also impair renal function and raise potassium in susceptible patients.
What this interaction means in plain words
Fenbufen and Nadolol can affect each other. The combination is often manageable, but it may need a change of dose, a change of timing, or extra checks while both are taken.
Why it happens
Inhibition of prostaglandin synthesis leads to sodium and fluid retention and reduced renal perfusion, opposing the blood pressure lowering effect of nadolol.
What to do
Monitor blood pressure when NSAIDs are used for more than a few days. Use the lowest effective NSAID dose or consider an alternative analgesic such as paracetamol.
What to ask your pharmacist

- Does the dose of either medicine need to change?
- Is there anything I should avoid, such as alcohol or certain foods, while on both?
