Certuss-D: Uses, indications and precautions when using

This is an automatically translated article.

Certuss-D is used to temporarily treat cough, nasal and sinus congestion (such as the common cold, flu) or other respiratory conditions (such as hay fever - allergic rhinitis, bronchitis ).

1. How to use Certuss-D

Decongestants (such as pseudoephedrine, phenylephrine) work by narrowing blood vessels to help relieve symptoms of nasal congestion and sinus pressure. An expectorant (such as guaifenesin) works by thinning and loosening airway mucus, clearing congestion and making breathing easier. Opioid cough suppressants (such as dextromethorphan, chlorphedianol) affect a certain part of your brain to help you stop coughing.
For children under 6 years of age, cough and cold products are considered safe or effective. Therefore, unless otherwise directed by a doctor, do not use this product to treat cold symptoms in children under 6 years of age. The use of certain products (such as long-acting tablets/capsules) is not recommended for children under 12 years of age. Ask your doctor for more details about using these medicines safely. These medicines cannot shorten the duration of the common cold or cure it, and can cause serious side effects. To reduce the risk of side effects, follow all dosing instructions carefully. Do not make your child drowsy by using this product. Some medicines may contain the same or similar ingredients. Talk to your doctor about other ways to relieve cough and cold symptoms (such as drinking enough fluids, using a humidifier or nasal drops, saline nasal spray).
If you are using an over-the-counter product for self-treatment, read all directions on the product label before taking this medication.
Determine the exact dose of the drug (liquid medicine) with a specialized measuring tool/spoon.
Based on factors such as age, medical condition, and response to treatment, your doctor will determine the right dose. Do not increase your dose or take this medication more often than directed by your doctor. Use the drug according to the recommendations of each age. There are many brands and forms of this medicine, so you need to read the instructions for each product carefully because the amount of cough suppressant and expectorant can vary between products.
If symptoms do not improve after 7 days of taking the medicine, or become progressively worse, if you have a fever, rash or persistent headache, or if you think you may have a serious medical problem , contact your doctor immediately.
