By doing so, it helps relieve the discomfort associated with congestion in your bronchial passageways.

Dosage and Administration

If you are an adult or a child aged 12 years and older, you should take 1 tablet every 4 hours as long as your symptoms continue. It’s important to drink a full glass of water with each tablet to help it work effectively. However, make sure not to take more than 6 tablets in a 24-hour period to avoid any potential side effects.

Renal Impairment

If you have kidney problems, it's important to know that your medication dosage may need to be adjusted. This is particularly true if your kidneys are not functioning well, which can be assessed through tests that measure how well they filter waste from your blood.

These tests help assess how well your liver is working and ensure that your treatment is appropriate for your condition. Always discuss any concerns with your doctor to ensure the best care for your health.
