Uses of Derivent Syrup

Treatment of Asthma

Benefits of Derivent Syrup

Treatment of Asthma
Asthma is a condition in which your airways become narrow and as a result, breathing becomes difficult. Derivent Syrup works by relaxing the muscles of the airways and widens it. As a result, it becomes easier for air to move in and out. It also thins and loosens mucus in the airways, helping you 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.

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 Derivent Syrup works

Derivent Syrup is a combination of two bronchodilators (Etofylline and Salbutamol) and an expectorant (Guaifenesin). The bronchodilators work by relaxing the muscles in the airways and widen the airways. Guaifenesin works by decreasing the stickiness of mucus (phlegm) and helps in its removal from the airways.

Quick tips

You have been prescribed Derivent Syrup for the treatment of asthma.
It does not work right away and should not be used to relieve sudden breathing problems. Always keep a fast-acting (rescue) inhaler with you.
If at any time your breathing gets worse, please contact your doctor or nurse for advice straightaway.
Inform your doctor if you have heart problems, high blood pressure or diabetes.
If you are due to have an operation or any dental treatment, tell the person carrying out the treatment which medicines you are taking, as some anesthetics can interfere with Derivent Syrup.
Do not smoke. Smoking causes irritation and damage to the lungs and will make your condition worse.
Try to keep your regular appointments with your doctor. This is so your doctor can review your condition on a regular basis.
