Interactions between your drugs

Moderate

lidocaine phenazopyridine

Applies to: Lidoject 1 (lidocaine) and Urelief Plus (butabarbital / hyoscyamine / phenazopyridine)

Using lidocaine together with phenazopyridine may cause methemoglobinemia, a rare 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 diseases of the heart or lungs, certain genetic predispositions, or glucose-6-phosphate dehydrogenase deficiency. Medical supervision may be necessary when medications that can cause methemoglobinemia are used together. Signs and symptoms of methemoglobinemia may occur immediately or hours after treatment. Patients or their caregivers should seek immediate medical attention if they develop gray discoloration of the skin, abnormal blood coloration, 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.

Moderate

lidocaine food

Applies to: Lidoject 1 (lidocaine)

Grapefruit juice may increase the blood levels of lidocaine, which may increase the risk of side effects such as low blood pressure, slow heart rate, irregular heart rhythm, difficulty breathing and convulsions. Cigarette smoking may reduce the blood levels of lidocaine, which may make the medication less effective. It is best to avoid smoking during lidocaine therapy. Consuming cruciferous vegetables (e.G., broccoli, brussels sprouts) may also reduce the blood levels of lidocaine. Talk to a healthcare professional 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.

Ask your doctor before using hyoscyamine together with ethanol. Use alcohol cautiously. Alcohol may increase drowsiness and dizziness while you are taking hyoscyamine. You should be warned not to exceed recommended dosages and to avoid activities requiring mental alertness. If your doctor prescribes these medications together, you may need a dose adjustment to safely take this combination. 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.
