Uses of Oncet 3D Tablet SR

Benefits of Oncet 3D Tablet SR

Asthma
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.

Side effects of Oncet 3D Tablet SR

Most side effects do not require any medical attention and disappear as your body adjusts to the medicine. Consult your doctor if they persist or if you’re worried about them

How to use Oncet 3D Tablet SR

Take this medicine in the dose and duration as advised by your doctor. Swallow it as a whole. Do not chew, crush or break it. Oncet 3D Tablet SR may be taken with or without food.

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.

Quick tips

  • You have been prescribed Oncet 3D Tablet SR for prevention of asthma.
  • Take it at the same time each day, preferably in the evening after food.
  • Do not take it with any fruit juices (such as apple, orange, or grapefruit) as they might make the drug less effective.
  • It does not work right away and should not be used to relieve sudden breathing problems. Use your rescue inhaler to control sudden difficulty in breathing. 
  • Your doctor may take regular blood test to monitor the level of drug in your body.
  • Avoid using antacids within 30 minutes of taking this medicine. It can make it harder for your body to absorb this medication.
  • Notify your doctor if you smoke or have an viral infection. Your dose may need to be adjusted.
  • Do not discontinue use without consulting your doctor, even if you feel better.
