While these risks of lacosamide, an antiepileptic drug used in partial-onset seizures, are by no mean inevitable a prudent patient and SO can take advantage the authorization this information. Cardiac issues, especially arrhythmias are one of the most severe risks. Clinical studies have reported that lacosamide prolongs the PR interval on an electrocardiogram (ECG), and this, in some cases may lead to symptoms related to atrioventricular block or other conduction disorders. Of special concern are the risks of these results in patients with preexisting heart disease or taking other drugs that affect cardiac rhythm. The prevalence of serious cardiovascular effects is still considered to be low at 0.5%–1%, although it could lead to severe consequences in vulnerable populations [10].
The other major issue concerns the CNS (central nervous system). Symptoms of dizziness, weakness and a condition known as ataxia can appear in about 25% of the cases. These effects may interfere with daily living and increase the likelihood of falls especially in elderly patients. Less commonly, CNS effects can progress to more serious conditions such as suicidal ideation or aggressive behavior and consequently become FDA warnings. Patients receiving lacosamide were also 1.2% more likely to experience suicidal ideation in a review from 2022 compared with other antiepileptics
There are also risks of taking Lacosamide with other medications. It is primarily cleared by the liver, and drug interactions can make other treatments more toxic or less effective. For example, adding CNS depressants (e.g., benzodiazepines or opioids) to lacosamide therapy may increase sedation and the risk of respiratory depression. Liver function should be monitored, and doses adjusted when patients are receiving other drugs by patient's prescriber.
However, chronic use can lead to tolerance necessitating dose adjustments that could provide an additional burden for patients due to increased side effects. Occurs With Regular Use of the Drug Up to 15 percent of those who regularly use marijuana can develop a problem with their gut (nausea and vomiting). While these lacosamide side effects are usually not problematic, they can become difficult to correct.
Hypersensitivity reactions, including angioedema and multiorgan hypersensitivity [see CONTRAINDICATIONS] are life-threatening. The reactions are severe and life threatening, the frequency of these is less than 1% but overall they will require medical attention. Swelling of the face, problems with breathing and skin rash also need to be followed by drug discontinuation.
The authors recommend cautious patient selection and continuous monitoring when using lacosamide due to these risks. Patients withheart disease, depression or polypharmacy are at increased risk and need to be closely monitored. Lacosamide is the useful AED despite these apprehension, when used carefully with remarkable seizure control benefits.
Current medical guidelines and consultation with specialists are recommended for a detailed review of potential adverse effects from lacosamide.
