Valtsu comp – Valsartan/hydrochlorothiazide uses, dose and side effects


80 mg/12.5 mg, 160 mg/12.5 mg and 160 mg/25 mg film-coated tablets

What Valtsu comp is and what it is used for

Valtsu comp film-coated tablets contain two active substances, valsartan and hydrochlorothiazide. Both substances help to control high blood pressure ( hypertension ).

  • Valsartan belongs to a group of drugs called “angiotensin II receptor blockers” and is used to lower high blood pressure. Angiotensin II is a substance found in the body that constricts the blood vessels, which increases blood pressure et. Valsartan works by inhibiting the effect of angiotensin II. This leads to vessels dilating and blood pressure falling.
  • Hydrochlorothiazide belongs to a group of drugs called thiazide diuretics (also called diuretics). Hydrochlorothiazide increases urine production, which also lowers blood pressure et.

Valtsu comp is used to treat high blood pressure that cannot be lowered sufficiently with just one of the substances.

High blood pressure increases the load on the heart and blood vessels. If left untreated, it can damage the blood vessels in the brain, heart, and kidneys and lead to stroke, heart failure, or kidney failure. High blood pressure increases the risk of a heart attack. A lowering of blood pressure et to a normal level reduces the risk of these diseases.

What you need to know before taking Valtsu comp

Do not take Valtsu comp:

  • if you are allergic to valsartan, hydrochlorothiazide, sulphonamide derivatives (substances chemically related to hydrochlorothiazide ), or any of the other ingredients of this medicine (listed in section 6).
  • if you have been pregnant for more than 3 months (it is also good to avoid Valtsu comp earlier in pregnancy, see the section “Pregnancy and breast-feeding”)
  • if you have severe liver disease, destruction of the small bile ducts in the liver ( biliary cirrhosis ) leads to bile accumulating in the liver (cholestasis)
  • if you have severe kidney disease
  • if you cannot produce urine ( anuria )
  • if you are being treated with an artificial kidney
  • if your potassium or sodium level in the blood is lower than normal or if the calcium level in the blood is higher than normal despite treatment
  • if you have gout
  • if you have diabetes or impaired kidney function and you are being treated with an antihypertensive medicine containing aliskiren

If any of the above apply to you, talk to your doctor, and do not take Valtsu comp.

Warnings and precautions

Talk to your doctor before taking Valtsu comp

  • if you are taking potassium-sparing medicines, potassium supplements, salt substitutes containing potassium, or other medicines that increase the amount of potassium in the blood, for example, heparin. Your doctor may need to check the amount of potassium in your blood regularly
  • if you have low levels of potassium in your blood
  • if you have diarrhea or severe vomiting
  • if you take high doses of water-reducing tablets ( diuretics )
  • if you have a serious heart condition
  • if you have heart failure or have had a heart attack. Follow your doctor’s instructions for the starting dose carefully. Your doctor may also check your kidney function
  • if you have narrowing of the renal arteries
  • if you have recently had a kidney transplant (received a new kidney)
  • if you have hyperaldosteronism. This is a disease in which your adrenal glands produce too much of the hormone aldosterone. If this applies to you, Valtsu comp should not be used
  • if you have liver or kidney disease
  • if you have ever experienced swelling of the tongue and face caused by an allergic reaction called angioedema while taking another medicine (including ACE inhibitors ), talk to your doctor. If these symptoms occur while taking Valtsu comp, stop taking Valtsu comp immediately and never take it again. See also section 4, “Potential side effects”
  • if you have a fever, rash, and joint pain, which may be signs of systemic lupus erythematosus ( SLE, a so-called autoimmune disease)
  • if you have diabetes, gout, high cholesterol or triglyceride levels in the blood
  • if you have had an allergic reaction when using other blood pressure-lowering agents belonging to this drug group ( angiotensin II receptor blockers) or if you have allergies or asthma
  • if your vision deteriorates or your eyes hurt. These may be symptoms of fluid accumulation in the eye (between the choroid and sclera) or increased pressure in the eye and may occur within hours to weeks of taking Valtsu comp. It can lead to permanent vision loss if left untreated. If you have previously had an allergic reaction to penicillin or sulfonamides, the risk of this side effect may be higher
  • if you are taking any of the following medicines used to treat high blood pressure:- an ACE inhibitor (for example enalapril, lisinopril, ramipril), especially if you have diabetes-related kidney problems.- the aliskiren
  • if you have had skin cancer or if you get an unexpected skin change during treatment. Treatment with hydrochlorothiazide, especially long-term use at high doses, may increase the risk of certain types of skin and lip cancer (non-melanoma skin cancer). Protect your skin from exposure to sunlight and UV rays while taking Valtsu comp.
  • if you have previously had breathing or lung problems (including inflammation or fluid in the lungs) after taking hydrochlorothiazide. If you experience severe shortness of breath or severe breathing problems after taking Valtsu comp, seek medical attention immediately.

Your doctor may need to check your kidney function, blood pressure, and the number of electrolytes (eg potassium ) in your blood at regular intervals.

See also the information under the heading “Don’t take Valtsu comp”.

Valtsu comp can increase the skin’s sensitivity to the sun.

You must tell your doctor if you think you are ( or may become ) pregnant. Valtsu comp is not recommended in early pregnancy and must not be used if you are more than 3 months pregnant, as the medicine may cause birth defects if used at this stage (see section “Pregnancy and breast-feeding”)

Children and young people

Use of Valtsu comp in children and adolescents (younger than 18 years) is not recommended.

Other medicines and Valtsu comp

Tell your doctor or pharmacist if you are taking, have recently taken, or might take any other medicines.

The treatment effect can be affected if Valtsu comp is taken together with certain other medicines. It may be necessary to change the dose, take other precautions or, in some cases, stop treatment with one of the drugs. This applies in particular to the following medicines:

  • certain antibiotics (rifamycin group), a medicine used to protect against transplant rejection (cyclosporin), or an antiretroviral medicine for HIV /AIDS infection (ritonavir). These medicines can enhance the effect of Valtsu comp

Valtsu comp with food, drink, and alcohol

Avoid drinking alcohol until you have spoken to your doctor. Alcohol can lower blood pressure further and/or increase the risk of you becoming dizzy or fainting.

Pregnancy and breastfeeding

If you are pregnant or breastfeeding, think you may be pregnant, or are planning to have a baby, ask your doctor or pharmacist for advice before using this medicine.


  • You must talk to your doctor if you think you are (or may become) pregnant. Usually, your doctor will suggest that you stop taking Valtsu comp before pregnancy or as soon as you know you are pregnant and will recommend another medicine for you instead. Valtsu comp should not be used in early pregnancy and should not be used during the last 6 months of pregnancy as it can cause serious birth defects.


  • Tell your doctor if you are breastfeeding or intend to start breastfeeding.
    Valtsu comp is not recommended during breastfeeding and your doctor may choose another treatment for you if you wish to breastfeed your baby, especially if your baby is a newborn or was born prematurely.

Driving ability and use of machinery

Before you drive a vehicle, use tools or machines, or perform activities that require concentration, make sure you know how Valtsu comp affects you. Like many other medicines for the treatment of high blood pressure, Valtsu comp can rarely cause dizziness and affect the ability to concentrate.

You are responsible for assessing whether you are fit to drive a motor vehicle or perform work that requires increased vigilance. One of the factors that can affect your ability in these respects is the use of drugs due to their effects and/or side effects. A description of these effects and side effects can be found in other sections. Read all the information in this leaflet for guidance. Discuss with a doctor or pharmacist if you are unsure.

Valtsu comp contains sodium
