What Irbesartan Winthrop is used for
Irbesartan Winthrop is used to lower high blood pressure, which doctors call hypertension.
Everyone has blood pressure. This pressure helps get your blood all around your body. Your blood pressure may be different at different times of the day, topamax is a depending on how busy or worried you are. You have hypertension (high blood pressure) when your blood pressure stays higher than is needed, even when you are calm and relaxed.
There are often no symptoms of high blood pressure. The only way of knowing that you have high blood pressure is to have your blood pressure checked on a regular basis. If high blood pressure is not treated it can lead to serious health problems, such as stroke, heart disease and kidney failure.Irbesartan Winthrop is also used in the treatment of kidney disease in patients with high blood pressure and type 2 diabetes.
How Irbesartan Winthrop works
Irbesartan Winthrop belongs to a group of medicines known as angiotensin-II receptor antagonists.Angiotensin II is a substance produced in the body that causes blood vessels to narrow. Irbesartan Winthrop blocks angiotensin-II and therefore widens your blood vessels, making it easier for your heart to pump blood throughout your body. This helps to lower your blood pressure.
Irbesartan Winthrop also slows the decrease of kidney function in patients with high blood pressure and type 2 diabetes.
Your doctor may have prescribed Irbesartan Winthrop for another reason. Ask your doctor if you have any questions about why Irbesartan Winthrop has been prescribed for you.
This medicine is only available with a doctor’s prescription.
There is no evidence that this medicine is addictive.

you are pregnant (or think you may be pregnant) or are planning to become pregnant;

Taking other medicines
Tell your doctor if you are taking any other medicines, including any that you buy without a prescription from your pharmacy, supermarket or health food shop.
Some medicines may affect the way others work. Also, some other medicines used to treat high blood pressure may have an additive effect with Irbesartan Winthrop in lowering blood pressure. This may happen with diuretics (fluid tablets). As a result you may need different amounts of your medicines.
It is important to tell your doctor if you are taking or plan to take any of the following:
potassium supplements, potassium-containing salt substitutes (you may need to have blood tests done regularly)
diuretics (fluid tablets)
medicines containing lithium (you may need to have blood tests done regularly).
anti-inflammatory medicines such as non-steroidal anti-inflammatory agents (for example diclofenac, ibuprofen) and COX-2 inhibitors (for example celecoxib) used to relieve pain, swelling and other symptoms of inflammation including arthritis. Taking Irbesartan Winthrop and an anti-inflammatory medicine alone or with a thiazide diuretic (fluid tablet) may damage your kidneys.It may also reduce the effect Irbesartan Winthrop has on lowering blood pressure.
a medicine containing aliskiren. Taking Irbesartan Winthrop with aliskiren may affect your blood pressure, electrolyte balance and your kidney function.
Your doctor and pharmacist may have more information on medicines to be careful with or avoid while taking Irbesartan Winthrop.
How to take Irbesartan Winthrop
How much to take
Your doctor will tell you how many tablets to take each day.
Usually patients start with one 150 mg tablet once a day. However, some patients may need a lower starting dose. Your doctor will tell you if this is necessary. The full blood pressure lowering effect of Irbesartan Winthrop should be reached about 4-6 weeks after starting treatment.
Depending on how your blood pressure responds, your daily dose of Irbesartan Winthrop may need to be increased. Most patients take either 150 mg or 300 mg each day.
In patients with high blood pressure and type 2 diabetes, 300 mg once daily is the preferred maintenance dose for slowing the progression of associated kidney disease.
Ask your doctor or pharmacist if you are unsure of the correct dose for you.
They will tell you exactly how much to take.
Follow the instructions they give you.
How to take it
Swallow the tablet whole with a glass of water.
It does not matter whether you take Irbesartan Winthrop tablets before or after food.
When to take it
Take Irbesartan Winthrop at about the same time each day.
Taking your tablets at the same time each day will have the best effect. It will also help you remember when to take the tablets.
How long to take it
Continue taking Irbesartan Winthrop until your doctor tells you to stop.
Irbesartan Winthrop helps to control your high blood pressure, but it does not cure it. Therefore Irbesartan Winthrop must be taken every day.
To help you remember to take your tablets each day, Irbesartan Winthrop tablets are supplied in a Calendar pack with the foil backing marked with the days of the week.This is just a way to help you to remember to take your tablets. All of the tablets in the pack are the same.
When you start a new strip of tablets, take the tablet marked “START” at the end of the blister strip. On the next day, take the tablet marked with the relevant day of the week.
Continue taking your tablets each day until all of the tablets are taken.Commence the next strip at “START” and continue as before.
If you forget to take it
If it is almost time for your next dose, skip the dose you missed and take your next dose when you are meant to.Otherwise, take it as soon as you remember, and go back to taking your tablets as you would normally.
Do not take a double dose to make up for the dose you missed.
This may increase the chance of you getting any unwanted side effects.
If you are not sure what to do, ask your doctor or pharmacist.
If you have trouble remembering to take your tablets, ask your pharmacist for some hints.
If you take too much (overdose)
Immediately telephone your doctor or Poisons Information Centre (telephone: 13 11 26) or go to Accident and Emergency at your nearest hospital, if you think that you or anyone else may have taken too much Irbesartan Winthrop.Do this even if there are no signs of discomfort or poisoning.
