Interactions between your drugs
lidocaine topical prilocaine topical
Applies to: EmReal (lidocaine / prilocaine topical) and EmReal (lidocaine / prilocaine topical)
Some of the medication in prilocaine topical is absorbed through the skin into the bloodstream and may cause interactions with other medications such as lidocaine topical. When used together, this combination may increase the risk of methemoglobinemia, a condition that can lead to oxygen deprivation in tissues and vital organs due to reduced oxygen-carrying capacity of the blood. Individuals may be more susceptible to developing methemoglobinemia during treatment with these medications if they are very young (especially neonates and infants) or have anemia, diseases of the heart or lungs, blood circulation disorders, liver cirrhosis, shock, sepsis, and certain genetic predispositions such as NADH cytochrome-b5 reductase deficiency, glucose-6-phosphate dehydrogenase deficiency, and hemoglobin M. In addition, excessive use of prilocaine topical such as application of large doses or on larger than recommended areas, as well as use on inflamed or abraded areas or broken skin, can increase absorption and result in high blood levels of the medication. Close medical supervision is necessary when medications that can cause methemoglobinemia are used together. Signs and symptoms of methemoglobinemia may be delayed by several hours after treatment with prilocaine topical. Patients (or their caregivers) should seek immediate medical attention if they develop a gray discoloration of the skin, mouth, or nail bed; nausea; headache; dizziness; lightheadedness; fatigue; shortness of breath; rapid or shallow breathing; a rapid heartbeat; palpitation; anxiety; or confusion. It is important to tell your doctor about all other medications you use, including vitamins and herbs. Do not stop using any medications without first talking to your doctor.
tocainide lidocaine topical
Applies to: tocainide and EmReal (lidocaine / prilocaine topical)
Some of the medication in lidocaine topical may be absorbed into the bloodstream following local application. Using lidocaine topical together with tocainide may increase the risk of side effects of both drugs. Although serious side effects are not very common with topically applied medications because only limited amounts of the medication generally get absorbed into the bloodstream from the skin, they can sometimes occur. Contact your doctor if your condition changes or you experience chest pain, palpitations, nausea, vomiting, lightheadedness, nervousness, dizziness or tremors. You may need more frequent monitoring to safely use both medications. Talk to your doctor if you have any questions or concerns. It is important to tell your doctor about all other medications you use, including vitamins and herbs. Do not stop using any medications without first talking to your doctor.
