What is the treatment of your condition?
Mostly, nasal congestion occurs due to a cold, which results from a viral infection. In most cases, the symptoms disappear without treatment. Treatments such as Congestal tabs can be used to relieve nasal congestion, and a nasal spray containing oxymetazoline can be used twice daily in the nose. In addition to inhaling warm water vapor (nasal fumigation), it is also possible to get benefit from using an antihistamine such as loratadine once a day for 5 days. It is recommended to drink a lot of warm liquids such as anise, chamomile, and ginger, while using a pain reliever and fever reducer such as paracetamol. Bacterial infections, an antibiotic such as Augmentin may be used
