Full information about Theolair SR

General Information on Theolair SR

The generic name of Theolair SR is theophylline. This drug falls under the category of bronchodilators. Theophylline is an alkaloid found in caffeine in tea leaves and has the same chemical and pharmacologic properties as caffeine. Theolair SR is a widely used drug for treating symptoms of emphysema, asthma and bronchitis. It is also helpful in treating other respiratory diseases which result in narrowing of the airways. The drug works by relaxing the muscles in the chest and lungs, thereby resulting in increased amounts of air flow through the bronchi. Patients should buy Theolair SR online only if their doctors have prescribed it for their conditions.

Side effects of Theolair SR

Patients should seek urgent medical attention if they develop any signs of allergic reactions while on Theolair SR. These include rash, hives, trouble breathing, and swelling of the face or mouth. The drug should be discontinued immediately and patients should consult the doctor right away if they suffer from more serious side effects like seizures, severe nausea and vomiting, tachycardia, arrhythmias, insomnia, bloody emesis, high and persistent fever, and shakiness. There are also some minor side effects associated with Theolair SR including mild nausea and vomiting, weight loss, dizziness, headache, and lightheadedness.


Theolair SR has been reported to hamper alertness in some cases. In such a scenario, patients should be careful before driving or operating heavy machinery that call for alertness. Caffeine use must also be minimized while you are on Theolair SR, as caffeine tends to increase the side effects of this medication. The drug should be taken with a full glass of water and must never be crushed, chewed, or broken, as doing this decreases the efficacy of this medication significantly. However, there may be times when you doctor tells you to take it in a broken form depending on the symptoms. Theolair SR should be stored at room temperature and away from heat, direct light, and moisture. An overdose of the medication can result in serious medical complications including seizures, which are mostly fatal and can cause permanent brain damage or even death. Patients should also never take an overdose or double dose just to make up for a missed dose.

Theolair SR Dosage

The dosage of Theolair SR depends on the condition and severity of the symptoms. This medication usually comes in Theolair SR 200 mg and Theolair SR 300 mg strengths and is white in color, though other doses are also available. The usual dose is Theolair SR 300 mg twice or thrice a day, and the dose can be reduced to 200 mg when the symptoms start to subside.


Before you buy Theolair SR, inform your doctor if you are using drugs such as Tegretol, Tagamet, erythromycin, propranolol, or rifampin. These drugs have been found to interact with Theolair SR when used concurrently. You should also inform your doctor if you are on any herbal products, vitamins or minerals. Patients should consult their doctor before they buy Theolair SR if they are on other medications at present.
