Eritel 80-AM Tablet contains two medications, both of which help to control high blood pressure. It lowers the blood pressure by relaxing the blood vessels and making it easier for your heart to pump blood around your body. This will reduce your risk of having a heart attack or a stroke. Eritel 80-AM Tablet may be taken on an empty stomach or along with food. However, it is better to take it regularly at a fixed time each day, as recommended by your doctor. The dose will depend on your condition and how you respond to the medication. It’s important to keep taking this medication even if you feel well. By lowering your blood pressure, it is reducing your risk of heart attack or stroke so do not stop taking it unless your doctor tells you to. You can help this medication work better by making a few changes to your lifestyle such as keeping active, stopping smoking, and eating a low salt and low-fat diet. The most common side effects of this medication include swelling in your ankles or feet (edema), headache, sleepiness, dizziness, tiredness, and upset stomach. Since it may cause sleepiness and dizziness, do not drive or do anything requiring concentration until you know how it affects you. Talk to your doctor if any of the side effects bother you or will not go away.
