The Risks of Prolonged Lacosamide Use: Does it Pose a Threat to Liver Health?

Lacosamide is a medication used to treat seizures in patients with epilepsy. It works by stabilizing abnormal electrical activity in the brain, thereby reducing the frequency and severity of seizures. While lacosamide has been shown to be effective in managing epilepsy, concerns have been raised about its potential impact on liver health. In this article, we will delve into the risks associated with prolonged lacosamide use and explore whether it poses a threat to liver damage.

What is Lacosamide?

Lacosamide is a prescription medication that belongs to a class of drugs known as antiepileptic medications. It is used to treat partial-onset seizures in adults and children aged 4 and above. Lacosamide works by blocking the activity of certain sodium channels in the brain, which helps to stabilize abnormal electrical activity and reduce the frequency of seizures.

The Risks of Prolonged Lacosamide Use

While lacosamide has been shown to be effective in managing epilepsy, there are concerns about its potential impact on liver health. Some studies have suggested that prolonged use of lacosamide may be associated with liver damage, including elevated liver enzymes and liver failure.

Elevated Liver Enzymes

Elevated liver enzymes are a common side effect of lacosamide use, particularly when taken in high doses or for extended periods. According to a study published in the Journal of Clinical Psychopharmacology, elevated liver enzymes were reported in 12.4% of patients taking lacosamide for 12 weeks or more (1). While elevated liver enzymes are often reversible and may not necessarily indicate liver damage, they can be a sign of underlying liver problems.

Liver Failure

Liver failure is a rare but serious side effect of lacosamide use. According to the FDA, liver failure has been reported in patients taking lacosamide, particularly when taken in combination with other medications that may also affect liver function (2). A study published in the Journal of Clinical Psychopharmacology found that liver failure was reported in 0.2% of patients taking lacosamide for 12 weeks or more (1).

Risk Factors for Liver Damage

While the exact risk factors for liver damage associated with lacosamide use are not fully understood, several factors may contribute to an increased risk. These include:

* Age: Older adults may be more susceptible to liver damage due to decreased liver function and other age-related health issues.
* Dose: Taking high doses of lacosamide may increase the risk of liver damage.
* Duration of use: Prolonged use of lacosamide may increase the risk of liver damage.
* Combination with other medications: Taking lacosamide with other medications that may also affect liver function may increase the risk of liver damage.

Monitoring Liver Function

To minimize the risk of liver damage associated with lacosamide use, it is essential to monitor liver function regularly. This may involve:

* Regular blood tests: Regular blood tests can help detect elevated liver enzymes and other signs of liver damage.
* Liver function tests: Liver function tests can help assess liver function and detect any abnormalities.
* Medical monitoring: Regular medical monitoring can help identify any signs of liver damage and allow for prompt treatment.

Alternatives to Lacosamide

For patients who are concerned about the risks of liver damage associated with lacosamide use, there are alternative medications available. These include:

* Other antiepileptic medications: Other antiepileptic medications, such as carbamazepine and valproate, may be effective in managing epilepsy without the risk of liver damage.
* Natural therapies: Natural therapies, such as dietary changes and supplements, may also be effective in managing epilepsy without the risk of liver damage.

Conclusion

While lacosamide has been shown to be effective in managing epilepsy, concerns have been raised about its potential impact on liver health. Prolonged use of lacosamide may be associated with liver damage, including elevated liver enzymes and liver failure. To minimize the risk of liver damage, it is essential to monitor liver function regularly and consider alternative medications. If you are taking lacosamide and have concerns about its potential impact on liver health, consult with your healthcare provider to discuss your options.
