Contents of the Package Leaflet
Olmesartan/Hydrochlorothiazide Normon contains two active substances, olmesartan medoxomil and hydrochlorothiazide, which are used to treat high blood pressure (hypertension):
Olmesartan/Hydrochlorothiazide Normon will only be given if treatment with olmesartan medoxomil alone has not adequately controlled your blood pressure. The combined administration of both active substances in Olmesartan/Hydrochlorothiazide Normon helps to reduce blood pressure more than if each substance were administered alone.
You may already be taking medications to treat high blood pressure, but your doctor may believe it is necessary for you to take Olmesartan/Hydrochlorothiazide Normon to lower it further.
High blood pressure can be controlled with medications like Olmesartan/Hydrochlorothiazide Normon tablets. Your doctor has probably also recommended that you make some lifestyle changes to help lower your blood pressure (such as losing weight, quitting smoking, reducing alcohol consumption, and reducing salt intake in your diet). Your doctor may also have recommended that you exercise regularly, such as walking or swimming. It is essential to follow your doctor's advice.
Do not take Olmesartan/Hydrochlorothiazide Normon
If you think you have any of these conditions, or are unsure, do not take the tablets. Consult your doctor and follow their advice.
Warnings and Precautions
Consult your doctor before starting to take Olmesartan/Hydrochlorothiazide Normon
Consult your doctor if you experience abdominal pain, nausea, vomiting, or diarrhea after taking Olmesartan/Hydrochlorothiazide Normon. Your doctor will decide whether to continue treatment. Do not stop taking Olmesartan/Hydrochlorothiazide Normon on your own.
If you experience a decrease in vision or eye pain, these could be symptoms of fluid accumulation in the vascular layer of the eye (choroidal effusion) or an increase in eye pressure, and can occur within a few hours to a week after taking Olmesartan/Hydrochlorothiazide Normon. This can lead to permanent vision loss if not treated. If you have previously had an allergy to penicillin or sulfonamide, you may be at higher risk of developing it.

Your doctor may want to monitor your kidney function, blood pressure, and electrolyte levels in your blood (such as potassium) at regular intervals.

Olmesartan/Hydrochlorothiazide Normon may cause an increase in blood fat and uric acid levels (which can cause gout - painful swelling of the joints) in the blood. Your doctor will probably want to perform a blood test from time to time to monitor these possible changes.
A change in blood levels of certain chemicals called electrolytes 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 of weakness, slowness, fatigue, drowsiness or restlessness, nausea, vomiting, decreased need to urinate, rapid heartbeat.
