Side Effects

The most common side effects of Carnitor include:

  • Nausea/vomiting
  • Abdominal cramps
  • Diarrhea
  • Seizures 

Speak with your doctor or pharmacist for a full list of side effects that applies to you.


Gastrointestinal reactions may result from a too rapid consumption of carnitine. They should be consumed slowly and doses should be spaced evenly throughout the day to maximize tolerance.

The safety and efficacy of oral levocarnitine has not been evaluated in patients with renal insufficiency. Chronic administration of high doses of oral levocarnitine in patients with severely compromised renal function or in ESRD patients on dialysis may result in accumulation of the potentially toxic metabolites, trimethylamine (TMA) and trimethylamine-N-oxide (TMAO), since these metabolites are normally excreted in the urine.

Mutagenicity tests performed in Salmonella typhimurium, Saccharomyces cerevisiae, and Schizosaccharomyces pombe indicate that levocarnitine is not mutagenic. No long-term animal studies have been performed to evaluate the carcinogenic potential of levocarnitine.


One of the possible drug interactions with Carnitor:

  • Warfarin

Speak with your doctor or pharmacist for more information. 


Store at controlled room temperature (77ºF). 

Pharmacist Tips

  • Monitoring should include periodic blood chemistries, vital signs, plasma carnitine concentrations and overall clinical condition.
  • The recommended oral dosage for adults is 990 mg two or three times a day using the 330 mg tablets, depending on clinical response.
  • There have been no reports of toxicity from levocarnitine overdose.
