The possible side effects of copastin are nausea, dry mouth, anorexia, and drowsiness. Copastin is a medication used to treat cough. The active ingredient of copastin is cloperastine hydrochloride. This medication is allowed to consume with or without food. This medication should be used with precaution among pregnant ladies, cystic fibrosis patients, and breastfeeding mothers. The common causes of cough are:

  • Coronavirus disease 2019 or COVID-19
  • Common cold
  • Cigarette smoking
  • Asthma
  • Chronic obstructive airway disease
  • Postnasal drip
  • Sinus infection
  • Acid reflux disease or gastroesophageal reflux disease (GERD)
  • Due to side effects of certain medications like angiotensin-converting enzyme inhibitors (ACEIs)

 Cough is a normal reflex in humans. However, prolonged cough is usually a symptom of certain diseases. Coughing once in a while is normal as this reflex helps to clear the airway and prevent any foreign bodies from entering the airway. The cough reflex is an airway protective mechanism. Cough is divided into two main types. They have a dry cough and a wet cough. Some diseases will cause a dry cough and some may cause a wet cough. A dry cough is when there is no phlegm produced and expelled upon coughing. Phlegm is ejected upon coughing if you are having a wet cough.

 Postnasal drip is the state where the phlegm or mucus drop down through your throat from the nose. Postnasal drip can be caused by sinusitis, common cold, or allergic reaction. Acid reflux or GERD results in acid vapor irritation of the airway. This irritation triggers a cough reflex to protect the airway. ACEIs are known to cause coughing. ACEIs are used to treat and control blood pressure in hypertensive patients. The examples of ACEIs are enalapril and captopril.

 Virus infection is the main cause of the common cold. Virus invasion into your airway will cause you to suffer from the common cold. The symptoms of the common cold are:

  • Fever
  • Sore throat
  • Runny nose
  • Cough
  • Sneezing
  • Chest discomfort
  • Chest congestion

 The common cold is usually a self-limiting condition in adults. However, the common cold in children can be a serious illness. For adults, consuming cold and cough medicines like copastin will help to reduce your symptoms. However, it won’t speed up your recovery. Our immune systems will do their job to clear the infection. Smoking contains numerous chemicals and it will cause cough as a reflex to eliminate those substances if you are new to smoking. However, if you are a chronic smoker, coughing is a sign that your lungs or airway is damaged. Quit smoking is the best thing to do. If you are not a smoker, do not start as it is not cool and dangerous. There are various ways to quit smoking. Nicotine replacement therapy is available to help smokers in quitting. Visit a doctor for the therapy.

  Asthma is a chronic airway disease characterized by excessive mucus production, airway inflammation, and airway narrowing. Asthma runs in the family and a cure is not yet available. Medications are meant for control of the disease. One of the keys to preventing asthma attacks is to avoid triggering factors or allergen. Asthma is somehow an excessive allergy reaction that takes place in the airway.

 The virus that causes (COVID-19) is now known as severe acute respiratory syndrome coronavirus (SARS-CoV-2). Previously, this virus was known as 2019-nCov. The genetic sequencing of this virus was nearest to two bat coronaviruses. Till now, it is most likely that the bat is the primary source of this infection. SARS-CoV-2 is the latest name for the virus causing this disease and it has been found in patients’ stool, blood, semen, and tears. The transmission through stool, blood, and semen is still inconclusive.
