What Are The Possible Drug Interactions of Relispa?

  1. Alcohol: Combining Relispa with alcohol can increase the risk of dizziness and drowsiness. It’s advisable to avoid alcohol while taking this medication.
  2. Other antispasmodic medications: Taking multiple antispasmodic medications together may lead to an additive effect and increase the risk of side effects. It’s generally not recommended to use Relispa concurrently with other antispasmodics.
  3. CYP3A4 inhibitors: Relispa is metabolized in the liver, and drugs that inhibit the CYP3A4 enzyme may affect its metabolism. This can lead to increased Drotaverine levels in the bloodstream, potentially causing stronger effects or side effects. Common CYP3A4 inhibitors include certain antifungal medications, macrolide antibiotics, and some antiretroviral drugs.
  4. CYP3A4 inducers: Drugs that induce the CYP3A4 enzyme may accelerate the metabolism of Relispa, potentially reducing its effectiveness. Rifampicin, an antibiotic used to treat tuberculosis, is an example of a CYP3A4 inducer.
  5. Central nervous system depressants: Combining Relispa with other medications that have sedative effects, such as benzodiazepines, opioids, or certain sleep medications, can increase the risk of drowsiness and dizziness.
  6. Medications affecting heart rate: Some drugs, like beta-blockers and certain antiarrhythmic medications, may interact with Relispa and potentially lead to changes in heart rate.
  7. Grapefruit and grapefruit juice: Grapefruit and its juice can interact with a variety of medications, including Relispa. It can inhibit the metabolism of the drug, potentially leading to increased levels in the bloodstream.
