What Are The Possible Drug Interactions of Myonal?

  1. CNS depressants: Myonal can cause drowsiness and central nervous system (CNS) depression. Combining it with other CNS depressants, such as alcohol, sedatives, hypnotics, or certain antidepressants, may increase the risk of excessive sedation.
  2. Antihypertensive drugs: Myonal may have additive effects with medications that lower blood pressure. Combining it with other antihypertensive drugs could lead to further blood pressure reduction.
  3. Medications affecting liver enzymes: Myonal is metabolized in the liver, so drugs that affect liver enzymes may influence its metabolism. Care should be taken when using Myonal with drugs known to induce or inhibit liver enzymes.
  4. Fluvoxamine: The antidepressant fluvoxamine may increase the blood levels of Myonal, potentially leading to an increased risk of side effects. If co-administration is necessary, close monitoring is advised.
  5. Cimetidine: Cimetidine, an H2 receptor antagonist used to treat ulcers, may increase the blood levels of Myonal, potentially leading to an increased risk of side effects.
  6. Erythromycin: Erythromycin, an antibiotic, may increase the blood levels of Myonal, potentially leading to an increased risk of side effects.
  7. Antifungal medications: Some antifungal medications, such as ketoconazole and itraconazole, may interact with Myonal and increase its blood levels.
