Drug Interactions

• Lidocaine+tramadol- Tramadol may rarely cause seizures, and combining it with other medications that can also cause seizures such as lidocaine may increase that risk. The interaction may be more likely if you are elderly, undergoing alcohol or drug withdrawal, have a history of seizures, or have a condition affecting the central nervous system such as a brain tumour or head trauma.
• Lidocaine+bupropion- Bupropion may rarely cause seizures, and combining it with other medications that can also cause seizures such as lidocaine may increase that risk. The interaction may be more likely if you are elderly, undergoing alcohol or drug withdrawal, have a history of seizures, or have a condition affecting the central nervous system such as a brain tumour or head trauma.
• Lidocaine+conivaptan- Talk to your doctor before using lidocaine together with conivaptan. Combining these medications may significantly increase the blood levels and effects of lidocaine. This can increase the risk of serious side effects such as irregular heart rhythm and other cardiovascular problems.
• Lidocaine+dofetilide- Using dofetilide together with lidocaine can increase the risk of an irregular heart rhythm that may be serious and potentially life-threatening. You may be more susceptible if you have a heart condition called congenital long QT syndrome, other cardiac diseases, conduction abnormalities, or electrolyte disturbances.

Lidocaine belongs to a class of medications called local anaesthetics. It works by stopping the sensation of pain by acting on peripheral nerves in the body.
