About Telvok CH 80 Tablet 10's

Telvok CH 80 Tablet 10's is a prescription medicine used to treat high blood pressure (hypertension). By lowering elevated blood pressure, it helps reduce the risk of serious cardiovascular events like strokes and heart attacks. This medication is typically prescribed when a single medicine is not enough to control your blood pressure effectively.

For the best results, take Telvok CH 80 Tablet 10's consistently at the same time every day, either with or without food. To help this medicine work effectively, your doctor will likely recommend adopting a low-salt diet and maintaining a regular, moderate exercise routine. Consistent daily use is essential, even if you feel completely healthy, as high blood pressure often has no obvious symptoms.

While taking Telvok CH 80 Tablet 10's, some people may experience mild side effects such as dizziness, fatigue, or an upset stomach. However, you must contact your doctor immediately if you experience serious symptoms like extreme muscle weakness, severe dizziness, or swelling of your face, lips, or throat.

Do not take this if you are pregnant, as this medicine can cause severe harm or death to an unborn baby. Before starting Telvok CH 80 Tablet 10's, you must talk to your doctor if you have a history of liver damage, severe kidney disease, or diabetes. It is also important to tell your doctor if you have experienced severe dehydration or abnormal electrolyte levels in your blood.

Certain medicines, including pain relievers like NSAIDs, can interact with Telvok CH 80 Tablet 10's and reduce its effectiveness or increase the risk of kidney damage. Consuming alcohol while taking this medicine can cause your blood pressure to drop too low, leading to severe dizziness or fainting. Pregnant or breastfeeding women should not use this medication, and elderly individuals should use it with caution under close medical supervision.

Directions for Use

Follow these step-by-step instructions to take Telvok CH 80 Tablet 10's safely and effectively:

  • Swallow the tablet whole with a full glass of water. Do not crush, chew, or break the tablet.
  • You can take this medicine with or without food, but try to take it at the same time every day to maintain steady levels in your body.

How Telvok CH 80 Tablet 10's Works

Telvok CH 80 Tablet 10's is a combination of two active ingredients that work in different ways to lower your blood pressure more effectively than either drug alone. The first active component is telmisartan, which belongs to a class of medicines called angiotensin II receptor blockers (ARBs). It works by blocking a natural substance in the body that causes blood vessels to tighten and narrow. By blocking this substance, telmisartan allows your blood vessels to relax and widen, making it easier for blood to flow through them. The second active component is chlorthalidone, which is a diuretic, often called a 'water pill.' It helps your kidneys remove extra water and salt (sodium) from your body through your urine. This reduces the total volume of fluid circulating in your blood vessels, which directly lowers the pressure against your artery walls.
