If your mother is taking Lacosamide and Altonil regularly for seizures, adding Mirnite 7.5 mg might be okay, especially if it's for sleep or anxiety. However, every brain responds differently, and even low doses can have unexpected effects in sensitive individuals. So instead of assuming it's safe just because it's commonly used, it's better to get her full medication list reviewed by her neurologist or psychiatrist before starting anything new.
Next Steps
Prioritize regular seizure control first. Sleep medicines can be added safely, but only when they are tailored to her case. Don't take chances without proper supervision.
