ZARTAN CO

ZARTAN CO, a medicine used to manage high blood pressure. This article is written to help you understand what ZARTAN CO is, how it works, how to take it safely, and what side effects you may experience. Please read this carefully and consult your doctor or pharmacist if you have any questions.


1. What it Is and What It Is Used For

ZARTAN CO is a combination medicine containing losartan potassium (an angiotensin II receptor blocker) and hydrochlorothiazide (a diuretic or water pill). Together, these ingredients help lower high blood pressure (hypertension) by relaxing blood vessels and removing excess fluid from the body. This helps reduce your risk of heart disease, strokes, and kidney problems.


2. What You Need to Know Before You Take ZARTAN CO

When Not to Take ZARTAN CO

Do not take ZARTAN CO if:

  • You’re allergic to losartan, hydrochlorothiazide, or sulpha drugs.
  • You’ve had skin cancers like basal or squamous cell carcinoma.
  • You have kidney or liver problems, or cannot urinate.
  • You suffer from angioedema (swelling under the skin).
  • You are pregnant or breastfeeding.
  • You have certain heart or blood vessel disorders.
  • You’re using lithium or specific diuretics that increase potassium.
  • You have untreated imbalances of potassium, sodium, or calcium.
  • You are under 18 years old (safety in children not established).

Warnings and Precautions

Let your doctor know if:

  • You’ve had dehydration, vomiting, or diarrhoea recently.
  • You have diabetes, high cholesterol, or gout.
  • You’re taking diuretics or lithium.
  • You’re black, as the medicine might be less effective.
  • You have asthma, lung disorders, or a history of skin cancer.
  • You suffer from heart failure or adrenal gland issues.

Use extra care when taking the first dose—dizziness may occur.
