QUESTION
About how much does an adult human brain weigh? See AnswerWhich drugs or supplements interact with lidocaine viscous?
Lidocaine topical administration results in low systematic or blood levels are therefore does not have any known clinically significant drug-drug interactions. The following drug interactions have been observed with intravenous lidocaine use.
Toxicity may result when the lidocaine is used with other local anesthetics or drugs which are structurally related to amide-type local anesthetics. Antiarrhythmic drugs such as mexiletine and amiodarone may increase blood concentrations of lidocaine.
Lidocaine is mainly metabolized or broken down by liver enzymes. Strong inhibitors of these liver enzymes such as fluvoxamine, erythromycin, and itraconazole may decrease the breakdown of lidocaine and cause an increase in its blood concentrations.
Cimetadine and beta-blockers such as propranolol may decrease blood levels of lidocaine by decreasing blood flow to the liver or by inhibiting liver enzymes that break down lidocaine.
Is lidocaine viscous safe to take if I'm pregnant or breastfeeding?
