Contents of the pack
Losartan/Hydrochlorothiazide Teva-ratio is a combination of an angiotensin II receptor antagonist (losartan) and a diuretic (hydrochlorothiazide).
Angiotensin II is a substance produced in the body that binds to receptors in blood vessels, causing them to constrict. This results in an increase in blood pressure. Losartan prevents the binding of angiotensin II to these receptors, causing the relaxation of blood vessels, which decreases blood pressure. Hydrochlorothiazide works by making the kidneys pass more water and salt. This also helps to reduce blood pressure.
Losartan/hydrochlorothiazide is indicated for the treatment of essential hypertension (high blood pressure).
Do not take Losartan/Hydrochlorothiazide Teva
Warnings and precautions
Consult your doctor or pharmacist before starting to take Losartan/Hydrochlorothiazide Teva tablets.
If you experience a decrease in vision or eye pain, they 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 hours to weeks after taking Losartan/Hydrochlorothiazide Teva. If left untreated, this can lead to permanent vision loss. You may be at greater risk if you have previously had an allergy to penicillin or sulfonamide.
Tell your doctor if you are pregnant (or think you may be). Losartan/Hydrochlorothiazide Teva is not recommended at the start of pregnancy, and should not be taken if you are more than 3 months pregnant as it may cause serious harm to your baby when administered from that time on (see section “Pregnancy and lactation”).
It is important that you inform your doctor before taking Losartan/Hydrochlorothiazide Teva:
Your doctor may check your kidney function, blood pressure, and blood electrolyte levels (e.g. potassium) at regular intervals.
