RI LS Tablet

Prescription Required

Product introduction

RI LS Tablet is a combination medicine used in the treatment of schizophrenia. It works by modulating the action of certain chemical messengers in the brain that affect thoughts.

RI LS Tablet is taken with or without food, preferably at night. However, it is advised to take it at the same time each day as this helps to maintain a consistent level of medicine in the body. Take this in the dose and duration advised by your doctor. If you miss a dose of this medicine, take it as soon as you remember. It is important not to stop this medicine suddenly without talking to the doctor as it may worsen your symptoms.

Some common side effects of this medicine include nausea, constipation, upper respiratory tract infection, urinary tract infection, tremor, blurred vision, and dryness in mouth. Initially, this medicine may cause a sudden drop in the blood pressure when you change positions, so it is better to rise slowly if you have been sitting or lying down. It also causes dizziness and sleepiness. So, do not drive or do anything that requires mental focus until you know how this medicine affects you. This medicine may increase your weight, blood sugar, and cholesterol but modifying your lifestyle by having a healthy diet and exercising regularly can reduce this side effect.



Your doctor should also know about all other medicines you are taking as many of these may make this medicine less effective or change the way it works. Inform your doctor if you are pregnant, planning pregnancy or breastfeeding.
