Dyphylline/guaifenesin Disease Interactions
There are 4 disease interactions with dyphylline/guaifenesin:
Dyphylline (Includes Dyphylline/guaifenesin) ↔ Renal Dysfunction
Severe Potential Hazard, High plausibility
Applies to: Renal Dysfunction
Dyphylline is eliminated almost entirely by the kidney. Drug accumulation may occur in patients with impaired renal function. Like other methylxanthines, high plasma levels of the drug may be associated with severe cardio- and neurotoxicity, sometimes without any previous warning. Therapy with dyphylline should be administered cautiously in patients with renal impairment. Dosage adjustments may be necessary. The relationship between plasma dyphylline levels and therapeutic as well as toxic effects has not been determined.
Methylxanthines (Includes Dyphylline/guaifenesin) ↔ Pud
Severe Potential Hazard, High plausibility
Applies to: Peptic Ulcer
Methylxanthines are known to stimulate peptic acid secretion. Therapy with products containing methylxanthines should be administered with extreme caution in patients with active peptic ulcer disease. Some manufacturers consider their use to be contraindicated under such circumstance.
Dyphylline (Includes Dyphylline/guaifenesin) ↔ Cardiotoxicity
Moderate Potential Hazard, Moderate plausibility
Applies to: Tachyarrhythmia, Angina Pectoris, Myocardial Infarction, Post MI Syndrome, Hyperthyroidism, Hypertension
Like other methylxanthines, dyphylline at high dosages may be associated with positive inotropic and chronotropic effects on the heart. Therapy with dyphylline and products containing dyphylline should be administered cautiously in patients with severe cardiac disease, hypertension, hyperthyroidism, or recent myocardial infarction. The relationship between plasma dyphylline levels and therapeutic as well as toxic effects has not been determined.
Methylxanthines (Includes Dyphylline/guaifenesin) ↔ Gerd
Moderate Potential Hazard, High plausibility
Applies to: Gastroesophageal Reflux Disease
Methylxanthines increase gastric acidity and may also relax lower esophageal sphincter, which can lead to gastric reflux into the esophagus. Therapy with products containing methylxanthines should be administered cautiously in patients with significant gastroesophageal reflux.

Drug Interaction Classification
The classifications below are a general guideline only. It is difficult to determine the relevance of a particular drug interaction to any individual given the large number of variables.
| Major | Highly clinically significant. Avoid combinations; the risk of the interaction outweighs the benefit. |
| Moderate | Moderately clinically significant. Usually avoid combinations; use it only under special circumstances. |
| Minor | Minimally clinically significant. Minimize risk; assess risk and consider an alternative drug, take steps to circumvent the interaction risk and/or institute a monitoring plan. |
