Insomnia may occur in some patients taking levamlodipine benzenesulfonate. Levamlodipine benzenesulfonate is a calcium in-flow blocker that is used to treat high blood pressure disease as well as angina pectoris. Most patients can tolerate levamlodipine benzenesulfonate well while taking it and it does not interfere with sleep. However, some patients may experience side effects such as headache, edema, fatigue, as well as insomnia, which can lead to difficulty in falling asleep at night, thus affecting the quality of sleep. It should be noted that it is contraindicated in patients who are allergic to dihydropyridine calcium antagonists. In case of patients with impaired hepatic function, the medication is administered in the same way as all other calcium antagonists and therefore great care should be taken. It is recommended to take Levamlodipine Benzenesulfonate Tablets under the supervision of a doctor and seek medical attention in case of discomfort.
