Contents of the pack
Olmesartan/Hydrochlorothiazide Normon contains two active substances, olmesartan medoxomil and hydrochlorothiazide, which are used in the treatment of high blood pressure (hypertension):
Olmesartan/Hydrochlorothiazide Normon will only be given if treatment with olmesartan medoxomil alone has not controlled your blood pressure sufficiently. The combination of the two active substances in Olmesartan/Hydrochlorothiazide Normon 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 think it is necessary for you to take Olmesartan/Hydrochlorothiazide Normon to lower it further.
High blood pressure can be controlled with medicines such as Olmesartan/Hydrochlorothiazide Normon tablets. Your doctor may also have recommended that you make some changes to your lifestyle, such as losing weight, stopping smoking, reducing the amount of alcohol you drink, and reducing the amount of salt in your diet. Your doctor may also have recommended that you exercise regularly, such as walking or swimming. It is important to follow your doctor's advice.
Do not take Olmesartan/Hydrochlorothiazide Normon
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 Olmesartan/Hydrochlorothiazide Normon
Talk to your doctor if you have stomach pain, nausea, vomiting, or diarrhea after taking Olmesartan/Hydrochlorothiazide Normon. Your doctor will decide whether you should 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 pressure in the eye, and can occur within 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 have a higher risk of developing it.

Olmesartan/Hydrochlorothiazide Normon 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 check for 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 check for 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, tiredness, sleepiness or restlessness, nausea, vomiting, decreased need to urinate, rapid heartbeat.
