Contraindications & Blackbox WarningsWith our commercial data, access important information on dangerous risks, contraindications, and adverse effects.Our Blackbox Warnings cover Risks, Contraindications, and Adverse Effects- Pharmacodynamics
Permethrin, a pyrethroid, is active against a broad range of pests including lice, ticks, fleas, mites, and other arthropods.
- Mechanism of action
Permethrin acts on the nerve cell membrane to disrupt the sodium channel current by which the polarization of the membrane is regulated. Delayed repolarization and paralysis of the pests are the consequences of this disturbance.

Drug Interaction Integrate drug-drug
interactions in your softwareAbacavir Abacavir may decrease the excretion rate of Permethrin which could result in a higher serum level. Aceclofenac Aceclofenac may decrease the excretion rate of Permethrin which could result in a higher serum level. Acemetacin Acemetacin may decrease the excretion rate of Permethrin which could result in a higher serum level. Acetaminophen Acetaminophen may decrease the excretion rate of Permethrin which could result in a higher serum level. Acetazolamide Acetazolamide may increase the excretion rate of Permethrin which could result in a lower serum level and potentially a reduction in efficacy. Acetylsalicylic acid Acetylsalicylic acid may decrease the excretion rate of Permethrin which could result in a higher serum level. Aclidinium Permethrin may decrease the excretion rate of Aclidinium which could result in a higher serum level. Acrivastine Permethrin may decrease the excretion rate of Acrivastine which could result in a higher serum level. Acyclovir Acyclovir may decrease the excretion rate of Permethrin which could result in a higher serum level.
