Does lacosamide raise blood pressure?
Lacosamide’s prescribing information lists nervous system side effects (such as dizziness, somnolence, and coordination problems) but high blood pressure is not a commonly reported or well-established adverse effect.
What side effects related to blood pressure are reported?
The most relevant cardiovascular issue reported with lacosamide is changes in heart rhythm, including PR-interval prolongation and, in some people, rhythm effects that can be associated with symptoms like dizziness or fainting. Those effects can make blood-pressure readings look abnormal in some situations, but this is not the same as lacosamide directly causing hypertension.
Can lacosamide still affect someone’s blood pressure indirectly?
Yes. Even if lacosamide is not a typical cause of high blood pressure, blood pressure can rise due to other factors that coincide with treatment, such as:
- stress, pain, or worsening seizures
- other medications (including stimulants, steroids, decongestants, or NSAIDs)
- underlying cardiovascular conditions
When should you get checked?
Seek prompt medical advice if you have symptoms that can go with significant blood-pressure problems (for example, severe headache, chest pain, shortness of breath, or fainting). If you measure consistently high readings after starting lacosamide, tell your clinician so they can review your overall medication list and consider other causes.
Quick practical next steps
If you’re concerned:
- Check your blood pressure at the same times each day for a few days and write down the readings.
- Don’t stop lacosamide abruptly without medical guidance, since seizure control can worsen.
