Taking sildenafil with other medicines and herbal supplements

Cautions with other medicines

Some medicines do not mix well with sildenafil.

Tell your pharmacist or doctor if you're taking any of these medicines before you start sildenafil:

  • nitrates for chest pain (angina)
  • riociguat for pulmonary hypertension

Mixing sildenafil with herbal remedies or supplements

It's not possible to say that herbal remedies and supplements are safe to take with sildenafil. They're not tested in the same way as pharmacy and prescription medicines.

Important: Medicine safety

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