Co-Diovan

Co-Diovan is a medication that is commonly used to reduce high blood pressure (hypertension). It is a combination of two principal ingredients and is often prescribed when one medicine does not help to control the blood pressure adequately.  Co-Diovan is made up of:  Valsartan – this is a medicine that treats high blood pressure and heart failure and is also sometimes given after a heart attack. It is also known by its brand name, Diovan. Valsartan is an ARB (angiotensin-2 receptor blocker) which works to relax and dilate the blood vessels, so the blood pressure drops and the heart can pump the blood around the body more easily.  Hydrochlorothiazide – this medicine contains ingredients that cause more frequent urination than usual. It is also used to reduce high blood pressure as urinating often gets rid of the excess salt and water in the body and allows the heart to pump blood more freely.   Hydrochlorothiazide is part of a commonly known group of medicines known as thiazides, which are called diuretics. Diuretics are sometimes referred to as water tablets because they flush excess water and salt out of the body by working on the kidneys. If there is too much salt in your body it can cause the fluid to increase in your blood vessels and raise your blood pressure.  Co-Diovan is often prescribed when Valsartan has worked successfully on its own. In some cases increasing the dose of Valsartan does not reduce the blood pressure, so Co-Diovan is an alternative option that a doctor may prescribe.   There are many medicines to reduce high blood pressure, and Co-Diovan is only one of them. Your doctor will decide which is most suitable for you. If you have high blood pressure you may be prescribed a combination of medicines to help reduce it as different types of medication can help adjust your blood pressure in different ways.   The combination of valsartan and hydrochlorothiazide make up the medication Co-Diovan. There is a higher percentage of valsartan in Co-Diovan.   There are different strengths of Co-Diovan available and you should always take the dosage prescribed by your doctor. Never take more than the prescribed dose to try and lower your blood pressure yourself, without talking to your doctor. 

Co-Diovan is a medication that is used to treat high blood pressure (hypertension). This condition can damage the blood vessels in the brain, heart and kidneys. Co-Diovan comes in tablet form and is available in different strengths. 

Co-Diovan contains two main ingredients, valsartan and hydrochlorothiazide, that work together to reduce high blood pressure.   

What is Co-Diovan? 

Co-Diovan is a medication that is commonly used to reduce high blood pressure (hypertension). It is a combination of two principal ingredients and is often prescribed when one medicine does not help to control the blood pressure adequately.

When is Co-Diovan used? 

Co-Diovan is used to control high blood pressure (hypertension). It is often used when a single medication, such as valsartan on its own, does not work well enough.  

High blood pressure is a common condition experienced by many people. If you have high blood pressure you may not know immediately, unless you are tested. However, it can cause serious medical problems such as a heart attack, a stroke, kidney disease or damage other organs, so it is important to get this condition treated. 

High blood pressure can occur in people who: 

  • Are obese or overweight; 
  • Smoke; 
  • Have a history of high blood pressure in their family; 
  • Suffer from any medical condition that affects your heart; 
  • Have high cholesterol; 
  • Have diabetes; 
  • Suffer from kidney disease; 
  • Drink excessive alcohol; 
  • Use the oral contraceptive pill; 
  • Take NSAIDs (non-steroidal anti-inflammatory drugs); 
  • Suffer from stress or anxiety; 
  • Take antidepressants. 

Therefore, you should have your blood pressure checked regularly to monitor it. Otherwise, you may not know you have high blood pressure until something serious happens, such as a heart attack.  

When a person suffers from high blood pressure the pressure in the arteries can damage the blood vessels. The arteries are the tubes inside the body that carry the blood away from the heart. As the heart beats it pumps the blood around the body through the arteries. The blood supplies the various organs in the body to ensure they are healthy and working well.  

However, high blood pressure (and unhealthy living) can cause hardening of the arteries, which means they can become blocked or lined with a plaque that reduces the correct flow of the blood. These can lead to a heart attack or other serious and/or fatal illness. 

If you have high blood pressure your doctor will take into account your circumstances and may prescribe you with medication such as Co-Diovan to help reduce it.  

If you are prescribed Co-Diovan or any other blood pressure-lowering medication (you can take more than one on medical advice) your doctor will also advise you to follow a healthy lifestyle. Medication can treat the symptoms, but a healthy lifestyle can greatly improve your condition. This includes: 

  • Eating a healthy diet; 
  • Doing regular exercise; 
  • Giving up smoking; 
  • Reducing your alcohol intake. 

How do you use Co-Diovan? 

The usual dose is one Co-Diovan tablet each day in the morning. Always follow the dose that has been prescribed by your doctor exactly. Your doctor will monitor your renal function with blood tests when starting the medication. 

You should take your tablet at the same time each day with or without food. Do not chew the tablet and take it with a glass of water.  

If you forget to take your Co-Diovan tablet you should not take another until the next one is due. You should never take a double dose as this could be dangerous.  

Because this medication can make you urinate more often is it not advisable to take it immediately before you go to bed or you are likely to have to get up in the night. You should take your Co-Diovan tablet a minimum of four hours before you go to bed to avoid this. 

You should not stop taking this medication without consulting a doctor as this could cause an increase in your blood pressure. 

Once you are prescribed medication to lower your blood pressure you will likely have to take it long-term. It is also important to visit your doctor regularly to have your blood pressure monitored and decide if your medication or dosage needs to be changed. You can buy blood-pressure monitoring machines for use at home, which are useful to monitor your blood pressure regularly. You can then show the doctor the readings over a period of time, for example, a month or three months. Most major chemists also offer a free blood pressure monitoring service. 

What dosages are there?

  • Co-Diovan 80 mg/12.5 mg;
