Read all of this leaflet carefully before you start taking this medicine, because it contains important information for you.
Contents of the Package Leaflet
Olmetec Plus contains two active substances, olmesartan medoxomil and hydrochlorothiazide, which are used to treat high blood pressure (hypertension):
Olmetec Plus will only be given if treatment with Olmetec (olmesartan medoxomil) alone has not controlled your blood pressure adequately. The combination of the two active substances in Olmetec Plus has been shown to be more effective at lowering blood pressure than either substance alone.
You may already be taking medicines to treat high blood pressure, but your doctor may think it is necessary for you to take Olmetec Plus to lower it further.
High blood pressure can be treated with medicines like Olmetec Plus tablets. Your doctor has probably also advised you to make some changes to your lifestyle to help lower your blood pressure (for example, losing weight, stopping smoking, reducing alcohol intake, and reducing the amount of salt in your diet). Your doctor may have also advised you to take regular exercise, such as walking or swimming. It is important to follow your doctor's advice.
Do not take Olmetec Plus
If you think any of these apply to you, or if you are not sure, do not take the tablets. Talk to your doctor and follow their advice.
Warnings and precautions
Talk to your doctor before you start taking Olmetec Plus.
Before taking the tablets, tell your doctorif you are taking any of the following medicines used to treat high blood pressure:
Your doctor may want to check your kidney function, blood pressure, and blood electrolyte levels (e.g. potassium) at regular intervals.
See also the information under the heading “Do not take Olmetec Plus”.

Tell your doctorif you get any of the following symptoms:
Your doctor may want to see you more often and perform some tests if you have any of these problems.
Talk to your doctor if you experience abdominal pain, nausea, vomiting, or diarrhoea after taking Olmetec Plus. Your doctor will decide whether to continue treatment. Do not stop taking Olmetec Plus on your own.
Olmetec Plus may cause an increase in blood fat and uric acid levels (which can cause gout - painful swelling of the joints). Your doctor will probably want to perform a blood test from time to time to monitor these possible changes.
A change in blood electrolyte levels may occur. Your doctor will probably want to perform a blood test from time to time to monitor this possible change. Some signs of electrolyte changes are: thirst, dry mouth, muscle pain or cramps, tired muscles, low blood pressure (hypotension), feeling weak, slow, tired, sleepy, or restless, nausea, vomiting, decreased need to urinate, rapid heartbeat. Tell your doctor if you notice any of these symptoms.
As with any other medicine that lowers blood pressure, excessive lowering of blood pressure in patients with impaired blood flow to the heart or brain may cause a heart attack or stroke. Therefore, your doctor will carefully monitor your blood pressure.
If you are going to have parathyroid function tests, you should stop taking Olmetec Plus before these tests are performed.
