Important Safety Information

What is LIKMEZ?
LIKMEZ is an antibiotic medicine used to treat:

  • trichomoniasis (a sexually transmitted infection) in adults
  • amebiasis (an infection caused by a parasite) in adults and children
  • anaerobic bacterial infections (infections caused by bacteria that do not need oxygen to survive) in adults

It is not known if LIKMEZ is safe and effective in children, except for the treatment of amebiasis.

Do not take LIKMEZ if you:

  • are allergic to metronidazole or other nitroimidazole medicines.
  • have taken disulfiram (medicine used to help people stop drinking alcohol) in the last 2 weeks. Taking LIKMEZ with disulfiram can cause psychotic symptoms (seeing or hearing things that are not really there) in people who drink alcohol.
  • drink alcohol or use products with propylene glycol during treatment with LIKMEZ and for at least 3 days after you stop taking LIKMEZ, because this can cause side effects including abdominal cramps, nausea, vomiting, headaches, and flushing.
  • have Cockayne Syndrome (a rare genetic disorder that affects growth and development).

Before taking LIKMEZ, tell your healthcare provider about all of your medical conditions, including if you:

  • have liver problems.
  • have kidney problems.
  • have medical problems that affect the brain.
  • have a yeast infection.
  • have a history of blood problems.
  • are breastfeeding or plan to breastfeed. LIKMEZ can pass into your breastmilk. Talk to your healthcare provider about the best way to feed your baby while taking LIKMEZ. If you are breastfeeding, you may consider pumping and throwing away your breast milk during treatment with LIKMEZ and for 48 hours after your last dose of LIKMEZ and feeding your infant stored human milk or formula.

Tell your healthcare provider about all the medicines you take, including prescription and over-the-counter medicines, vitamins and herbal supplements. LIKMEZ and other medicines can affect each other causing side effects.

Especially tell your healthcare provider if you take:

  • warfarin or other blood thinners (anticoagulants)
  • lithium
  • busulfan

  • Worsening yeast infection (candidiasis) symptoms in people with a known yeast infection or a yeast infection they were not aware of.
