Persistent dry cough, which usually worsens at night, despite having several causes, can be caused by an allergic reaction and in this case, the best thing to do is to combat the allergy with the use of an antihistamine remedy such as Loratadine, for example. However, one must find out the cause of the allergy and avoid exposure to this cause.
Persistent dry cough that after some time presents with catarrh can in some cases be tuberculosis and, if it occurs, it is important to make an appointment with a pulmonologist to indicate the best treatment.
How to cure
Treatment for persistent dry cough should be directed to resolve your cause. In the case of dry cough of allergic cause, besides the use of medicines prescribed by the doctor, it is important:
- Drink at least 1.5 liters of water per day because water helps to keep the airways hydrated and decreases throat irritation;
- Take 1 tablespoon of carrot syrup or oregano about 3 times a day. These syrups have antitussive properties, reducing coughing attacks. Here's how to make these syrups.
- Drink 1 cup of mint tea, about 3 times a day. Mint has tranquilizing, antitussive, mucolytic, expectorant and decongestant action, helping to relieve cough. To make the tea just add 1 teaspoon of dried or fresh mint leaves into a cup of boiling water and let stand for 5 minutes, strain and drink the following;
- Take medicine for persistent dry cough under medical supervision, such as Vibral, Notuss, Antuss or Hytos Plus, for example;
- Avoid dust inside the home, since contact with animals and cigarette smoke can be the cause of persistent dry cough.
Cases of persistent dry cough for more than 1 week deserve more attention, especially if the individual has asthma, bronchitis, rhinitis or any other chronic respiratory disease. It can mean a worsening of the condition and the need to take antihistamine or corticoid medications.
