Theox Effects and Usage




Theox - Pliva's Theophylline Generic Version

What kind of medication is Theox?

Theox is a brand name of theophylline. The medication has bronchodilator properties used to treat symptoms of difficulty breathing caused by respiratory diseases such as asthma, chronic bronchitis, or emphysema. Theox works by relaxing bronchial smooth muscle that surrounds the bronchial tubes of the lungs, thus widening air passages in the lungs and making breathing easier. It also improves contraction of the diaphragm.

Pliva Pharmaceuticals, Inc. manufactures a generic version of Theox available as Pliva 482 200 mg and Pliva 459 300 mg pills.

The medication is also marketed under other trade names that include: Nuelin, Quibron-T, Slo-Bid, Theolair, Theo-24, Uni-dur and Uniphyl.

What are possible side effects of using Theox?

Adverse reactions may include:

  • nausea
  • diarrhea
  • stomach pain
  • headache
  • dizziness
  • fast or irregular heartbeat
  • insomnia
  • restlessness
  • irritability
  • If overdosed, Theox may cause seizures, vomiting or skin rash.

    Unwanted effects of Theox can be increased if it is combined with other medications. They can also be increased when Theox is taken with fatty meals, which may result in the so called dose dumping (premature and exaggerated release of the drug).

    What is the recommended dose of Theox?

    The total daily dose may be calculated on the basis of 10 to 15 mg per 1 kilo of body weight. The total dose is divided into 2 to 4 equal parts taken regularly during the day. However, due to the fact that high amounts of Theox can be toxic, and the level of the medication in blood can be affected by many concomittant factors, the optimal dose should rather be determined by the physician who will monitor the level of the drug in your blood during several days or even weeks regularly.
