Slo-Bid Long Term Side Effects

Slo-Bid” refers to a brand of theophylline, which is a bronchodilator used to treat symptoms of asthma, chronic bronchitis, and other lung diseases. Theophylline helps in preventing and treating wheezing, shortness of breath, and chest tightness by relaxing and opening the air passages in the lungs.

As with many medications, theophylline can have potential side effects. While the short-term side effects, such as nausea, insomnia, and palpitations, are more commonly discussed, there are also potential long-term side effects to be aware of.

Long-Term Side Effects of Theophylline (Slo-Bid)

  1. Cardiac Issues: Long-term use of theophylline can increase the risk of certain cardiac issues, including arrhythmias or palpitations. This is especially significant in patients with a history of heart disease.
  2. GI Disturbances: Chronic use can lead to gastrointestinal issues such as nausea, vomiting, or abdominal pain. In some cases, it might exacerbate symptoms of GERD (Gastroesophageal Reflux Disease).
  3. Central Nervous System Effects: Over time, some people may experience nervousness, tremors, or seizures. Seizures are particularly concerning, and the risk increases with higher doses of theophylline.
  4. Bone Health: There’s some evidence suggesting that prolonged use of theophylline can have a negative impact on bone health, potentially increasing the risk of fractures.
  5. Adverse Drug Reactions: Theophylline has a narrow therapeutic index, which means there’s a small margin between therapeutic and toxic blood levels. Chronic use requires regular monitoring of blood levels to avoid toxicity.
  6. Liver and Kidney Function: Extended use can potentially affect liver and kidney function, especially in those with pre-existing conditions.
  7. Drug Interactions: Long-term usage can lead to increased chances of drug interactions with other medications, either decreasing the effectiveness of theophylline or increasing its toxicity.


It’s important to have regular check-ups and blood tests when using theophylline for an extended period. This helps in monitoring its levels in the bloodstream and ensuring that they remain within the therapeutic range.
