Sometimes we have a cough that bothers us for days and never goes away. Even if we drink syrups and do various things, it doesn't help. At a time like this, when you go to see a doctor, he may prescribe you a small, gel-like capsule. That medicine is called Benzonatate. Let's talk about this medicine today.
What is Benzonatate?
Simply put, Benzonatate is a cough suppressant. We also call these cough suppressants. It works by temporarily calming the cough reflex in our body. It's like telling our brain to "stop coughing now." You may see this medication under the brand names Tessalon Perles and Zonatuss.
Things you need to tell your doctor before taking this medicine
Before your doctor prescribes this medicine, he or she will need to know your complete medical history. Therefore, if you have any of the following conditions, be sure to tell them about them.
- If you have kidney disease or liver disease .
- If you have allergies to any other medicine, food, or dye, not just to benzonatate.
- If you are pregnant or trying to get pregnant .
- If you are a breastfeeding mother .
Based on this information, it will be easier for the doctor to decide whether this medication is right for you or not.
The medicine should be used in the right way.
The way you use this medicine is very important, so keep these points in mind.
- This capsule should be swallowed whole with a glass of water .
- Do not chew or crush the capsule for any reason. Doing so may cause irritation to your mouth, tongue, and throat. It can also cause serious side effects. Therefore, it is safest to swallow it whole.
- Take the medicine only when the doctor prescribes it, in the prescribed amount. Don't go to get it too often.
- This medicine is usually prescribed to children over 10 years of age in some cases. But it should only be given on the advice of a doctor.
Most importantly: This medicine is prescribed for you only. Do not give this medicine to someone else just because they have the same symptoms as you.
What if I miss a dose or take too much?
Imagine you forgot to take a dose of medicine. Take it as soon as you remember. However, if it is almost time for your next dose, skip the missed dose and take your next dose at the scheduled time. Never take two doses at once.
Now, if you think you have taken too much medicine, it is not a joke. Immediately call the National Poisons Information Centre at the Colombo National Hospital or go to the Emergency Department (ETU) of the nearest hospital. Treat this as an emergency.
