Contents of the pack and additional information

Olmesartán/Hidroclorotiazida Alter contains two active principles, olmesartán medoxomilo and hidroclorotiazida, which are used in the treatment of high blood pressure (hypertension):

• Olmesartán medoxomilo belongs to a group of medications called angiotensin II receptor antagonists. It reduces blood pressure by relaxing blood vessels.
• Hidroclorotiazida belongs to a group of medications called thiazide diuretics. It reduces blood pressure by contributing to the elimination of excess fluids, increasing urine production by the kidneys.

Olmesartán/Hidroclorotiazida Alter will only be given if treatment with Olmesartán (olmesartán medoxomilo) alone has not adequately controlled your blood pressure. The concurrent administration of both active substances in Olmesartán/Hidroclorotiazida Alter contributes to reducing 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 necessary for you to take Olmesartán/Hidroclorotiazida Alter to lower it further.

High blood pressure can be controlled with medications like Olmesartán/Hidroclorotiazida Alter tablets. Your doctor has probably also recommended that you make some lifestyle changes to help lower your blood pressure (for example, losing weight, quitting smoking, reducing alcohol consumption, and reducing the amount of salt in your diet). Your doctor may also have recommended that you engage in regular exercise, such as walking or swimming. It is essential to follow your doctor's advice.

Do not take Olmesartán/Hidroclorotiazida Alter

• If you are allergic to olmesartán medoxomilo or to hidroclorotiazida, or to any of the other components of this medication (listed in section 6) or to substances similar to hidroclorotiazida (sulfonamides).
• If you are more than 3 months pregnant. (It is also better to avoid Olmesartán/Hidroclorotiazida Alter at the beginning of pregnancy - see Pregnancy section).
• If you have severe kidney problems.
• If you have diabetes or kidney insufficiency and are being treated with a medication to lower blood pressure that contains aliskirén.
• If you have low levels of potassium or sodium in the blood, high levels of calcium or uric acid in the blood (with symptoms of gout or kidney stones), that do not improve with treatment.
• If you have severe liver problems, or yellowing of the skin and eyes (jaundice), or problems with bile drainage from the gallbladder (biliary obstruction, for example, by gallstones).
• Olmesartán/Hidroclorotiazida Alter contains soy lecithin. Do not use it in case of allergy to peanuts or soy.

If you think you have any of these cases, or are not sure, do not take the tablets. Talk to your doctor and follow their advice.

Warnings and precautions

• Aliskirén.

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

Contact your doctorif you experience any of the following symptoms:

• Severe, persistent diarrhea that causes significant weight loss. Your doctor will evaluate your symptoms and decide how to continue your blood pressure treatment.

This can lead to permanent vision loss if not treated.

Your doctor may want to see you more often and perform some tests if you have any of these problems.
