What Are The Possible Drug Interactions of Famopsin?

  1. Antacids: While typically safe to use together, taking Famopsin with antacids might affect the absorption of Famopsin. It’s advisable to separate their administration by at least 2 hours.
  2. Medications affected by stomach pH: Famopsin reduces stomach acid production. Drugs that require an acidic environment for absorption, such as some antifungal medications (ketoconazole, itraconazole) or antiviral drugs (atazanavir), might have reduced effectiveness when taken with Famopsin.
  3. Certain Antibiotics: Some antibiotics like cefuroxime, cefpodoxime, and cefditoren may have reduced absorption when taken with Famopsin. Separating their intake by a few hours can help mitigate this interaction.
  4. Medications metabolized by certain enzymes: Famopsin might interact with drugs metabolized by the liver enzyme CYP2D6, potentially affecting their levels in the body. Medications like metoprolol, tricyclic antidepressants (amitriptyline, nortriptyline), and certain antipsychotics can be affected.
  5. Medications causing QT prolongation: There may be a risk of QT prolongation (a heart rhythm disorder) when Famopsin is taken with drugs known to cause this effect, such as certain antibiotics, antipsychotics, or antidepressants.
  6. Warfarin and other blood thinners: Famopsin might interact with blood thinners, possibly increasing the risk of bleeding. Close monitoring of blood clotting parameters might be necessary if these medications are used together.
