Retafyllin 200mg Tablet 100s (Box)

Retafyllin 200mg Tablet is a controlled-release bronchodilator belonging to the methylxanthine class, with theophylline as its active ingredient. One thing many patients want to know upfront is that this is a slow-release tablet, so it works gradually over time rather than giving instant relief — it isn't meant to replace a rescue inhaler during a sudden breathing attack. Some people notice nausea, restlessness, headache, or a faster heartbeat, especially if the dose is too high for their body. Because theophylline levels in the blood can vary quite a bit between individuals, your doctor may want to monitor you periodically, particularly if you smoke, drink alcohol regularly, or take other medicines. If you ever feel unusually jittery, notice palpitations, or your stomach becomes very upset, it's worth checking in with your doctor rather than just pushing through it.

Dosage is individualised based on your condition, body weight, and response, typically starting at a conservative dose and adjusted by your doctor based on blood level monitoring. Do not increase your dose on your own, as theophylline has a narrow safety margin between an effective and an excessive dose.

• Nausea and vomiting
• Abdominal discomfort
• Headache
• Restlessness or nervousness
• Palpitations or rapid heartbeat
• Difficulty sleeping
• Increased urination
• Diarrhoea
• Dizziness

Store below 30°C in a cool, dry place, protected from light and moisture, in its original packaging. Keep out of reach of children.

• Take it consistently at the same time each day
• Do not crush or chew the controlled-release tablet
• Keep your regular blood monitoring appointments if advised
• Avoid sudden changes in caffeine intake or smoking habits without telling your doctor
• Always keep a rescue inhaler on hand for sudden breathing difficulty
• Store away from heat and humidity

Retafyllin tablets are taken by mouth, generally at the same time each day, and may be taken with meals to help reduce stomach discomfort. Swallow the tablet whole without crushing or chewing, as this is a controlled-release formulation designed to release the medicine slowly.

Retafyllin tablets generally remain stable for around 24–36 months from the date of manufacture when stored correctly and unopened. Always check the expiry date printed on the packaging before use.

The active ingredient is Theophylline 200mg, a methylxanthine bronchodilator in controlled-release tablet form.

Retafyllin should not be used in patients with a known hypersensitivity to theophylline or other xanthine derivatives, active peptic ulcer disease, or uncontrolled seizure disorders. Caution is required in patients with heart conditions, liver impairment, or hyperthyroidism.

Theophylline levels can be significantly affected by certain antibiotics, antifungals, and other medicines that alter liver metabolism, so it's important to disclose your complete medication list to your doctor. Caffeine, alcohol, and smoking can also affect theophylline levels, and high-fat meals may alter how the tablet is absorbed.
