Contents of the pack
Olmesartan/Hydrochlorothiazide Viatris contains two active substances, olmesartan medoxomil and hydrochlorothiazide, which are used to treat high blood pressure (hypertension):
You will only be given olmesartan medoxomil/hydrochlorothiazide if treatment with olmesartan medoxomil alone has not controlled your blood pressure adequately. The combination of the two active substances in this medicine has been shown to be more effective at lowering blood pressure than either substance alone.
You may already be taking medicines for high blood pressure, but your doctor may now want to treat you with olmesartan medoxomil/hydrochlorothiazide to lower it even more.
High blood pressure can be controlled with medicines such as olmesartan medoxomil/hydrochlorothiazide 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, giving up smoking, reducing the amount of alcohol you drink 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 this advice.
Do not take Olmesartan/Hydrochlorothiazide Viatris:
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
Consult your doctorbefore taking Olmesartan/Hydrochlorothiazide Viatris if you have any of the following health problems:
Your doctor may check your kidney function, blood pressure, and the levels of certain chemicals in your blood (such as potassium) at regular intervals.
Also, see the information in the "Do not take Olmesartan/Hydrochlorothiazide Viatris" section.
Your doctor may want to see you more often and do some tests if you have any of these conditions.
Olmesartan medoxomil/hydrochlorothiazide may cause an increase in the levels of fats and uric acid in your blood. Your doctor will probably want to do a blood test from time to time to check for these possible changes.
A change in the levels of certain chemicals (electrolytes) in your blood may occur. Your doctor will probably want to do a blood test from time to time to check for this possible change. Some signs of electrolyte changes are: thirst, dryness of the mouth, muscle pain or cramps, tired muscles, low blood pressure (hypotension), feeling of weakness, slowness, tiredness, sleepiness or restlessness, nausea, vomiting, less need to urinate, fast heartbeat. Tell your doctor if you notice any of these symptoms.
