Oncet 3D Tablet SR is a combination medicine used in the prevention of asthma. It relieves allergy symptoms such as runny nose, stuffy nose, sneezing, watery eyes and congestion or stuffiness. It also helps in relaxing the muscles of the air passages, thus widening it and making it easier to breathe.
Oncet 3D Tablet SR is taken with or without food in a dose and duration as advised by the doctor. The dose you are given will depend on your condition and how you respond to the medicine. You should keep taking this medicine for as long as your doctor recommends. If you stop treatment too early your symptoms may come back and your condition may worsen. Let your healthcare team know about all other medications you are taking as some may affect, or be affected by this medicine.
The most common side effects are nausea, vomiting, stomach pain, diarrhea, skin rash, itching, breathing difficulty, and headache. Most of these are temporary and usually resolve with time. Contact your doctor straight away if you are at all concerned about any of these side effects. This medicine may cause dizziness and sleepiness, so do not drive or do anything that requires mental focus until you know how this medicine affects you. Avoid drinking alcohol while taking this medicine as it can worsen your sleepiness.
Before taking it, you should tell your doctor if you have any kidney or liver diseases so that your doctor can prescribe a suitable dose for you. You should also tell your doctor if you are pregnant, planning pregnancy or breastfeeding.
Asthma is a condition in which your airways become narrow and as a result, breathing becomes difficult. Oncet 3D Tablet SR works by relaxing the muscles of the airways and widens it. It also gives relief from congestion or stuffiness by loosening mucus and helping to cough out. This makes you breathe easy and gives relief from symptoms such as tightness in your chest, shortness of breath, wheezing and coughing. Regular exercise and yoga can help improve the symptoms of asthma in the long term, in addition to improving overall health.

How Oncet 3D Tablet SR works
Oncet 3D Tablet SR is a combination of three medicines: Montelukast, Fexofenadine and Acebrophylline. Montelukast is a leukotriene antagonist. It works by blocking the action of leukotriene, a chemical messenger. This reduces inflammation in the airways and nose, and improves symptoms of allergies. Fexofenadine is an antiallergic which relieves symptoms like runny nose, watery eyes and sneezing. Acebrophylline is a mucolytic which thins and loosens mucus (phlegm), making it easier to cough out.
