Cautions with other medicines
Lidocaine can sometimes affect the way other medicines work. However, this is more likely when you're using lidocaine at higher doses or if you're having lidocaine injections.
If you're using your lidocaine treatment for mouth and throat as in the instructions, it usually will not affect any other medicines.
Speak to your pharmacist if you have any questions.
Mixing lidocaine with herbal remedies and supplements
There's not enough information to say that complementary medicines, herbal remedies and supplements are safe to take with lidocaine. 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.
Important: Medicine safety
Tell your doctor or pharmacist if you're taking any other medicines, including herbal remedies, vitamins or supplements.
