Product introduction

Kymolol 25 Tablet ER is also used to relieve the symptoms caused by an overactive thyroid gland. It may be prescribed alone or together with other medications. The dose and frequency depend on what you are taking it for and the severity of your condition. It may be taken on an empty stomach or with a meal, but take it regularly at the same time each day to get the most benefit. It may take several weeks before you get the full benefit of this medicine, and you may need to take it for the rest of your life. However, it is important to continue taking it even if you feel well. Most people with high blood pressure do not feel ill, and if you stop taking it, your condition may worsen.

Common side effects of Kymolol 25 Tablet ER include low blood pressure (hypotension), slow heart rate, headache, dizziness, and nausea. These are usually mild and short-lived. It may also cause shortness of breath or rash in some people. To reduce the risk of side effects, your doctor may start the medicine at a low dose and gradually increase it. Consult your doctor if the side effects bother you or do not go away.

Before taking it, let your doctor know if you have any liver problems. It may also not be suitable for people who have a slow heart rate, severe circulation problems, severe heart failure, or low blood pressure. Pregnant or breastfeeding mothers should also consult their doctor before taking it. You must talk to your doctor to find out whether this medicine is suitable for you to use. You should have your blood pressure checked regularly to make sure that this medicine is working properly. Avoid drinking alcohol, as it may increase certain side effects.

Uses of Kymolol Tablet ER

Benefits of Kymolol Tablet ER

Treatment of Angina (heart-related chest pain)
Kymolol 25 Tablet ER relaxes the blood vessels so that blood can flow more easily around your body and makes sure that your heart is getting a good supply of oxygen. This makes it less likely that you will suffer chest pain caused by angina. This medicine can help increase your ability to exercise and go about your daily life more easily by reducing the frequency of angina attacks. You should take it regularly and as long as it is prescribed for it to work effectively.

Treatment of Arrhythmia
Kymolol 25 Tablet ER is used to stabilize heart rhythms (particularly atrial fibrillation). It helps in normalizing an abnormal heart rhythm, preventing it from occurring in the first place, or slowing down the heart rate during an episode.

Prevention of Heart attack
Kymolol 25 Tablet ER helps lower your blood pressure and make it easier for your heart to pump blood around your body. This reduces the chances of you having a heart attack. It can also reduce the risk of dying if it is given immediately after a heart attack. This medicine needs to be taken regularly to be effective, so keep taking it even if you feel well. Do not stop without talking to your doctor.

Treatment of Hypertension (high blood pressure)
Kymolol 25 Tablet ER belongs to a group of medicine called long-acting beta-blocker. It works by blocking the effects of some chemicals on your heart and blood vessels. It slows down your heart rate and helps the heartbeat with less force. This lowers your blood pressure and helps in reducing your risk of having a stroke, a heart attack, other heart problems, or kidney problems in the future. This medicine needs to be taken regularly to be effective, so keep taking it even if you feel well. Do not stop without talking to your doctor.

Prevention of Migraine
Kymolol 25 Tablet ER helps change electrical activity in the brain, reduce the flow of blood in your brain, or increase activity in a region of the brain associated with migraines.
