Important Warnings

Use with caution in liver disease. Domperidone may increase risk of QT prolongation/serious heart rhythm problems—avoid in patients with known QT prolongation, significant electrolyte disturbances, or heart failure; do not exceed prescribed dose. Long-term PPI use may be associated with low magnesium, vitamin B12 deficiency, fractures, and increased risk of gastrointestinal infections; use the lowest effective dose. Seek medical advice if alarm symptoms occur (blood in stool/vomit, persistent vomiting, unexplained weight loss, difficulty swallowing).

Drug Interactions

Zomset D 40MG Cap may interact with the following:

QT-prolonging drugs (e.g.
amiodarone
sotalol
certain antipsychotics)
strong CYP3A4 inhibitors (e.g.
ketoconazole
itraconazole
clarithromycin
erythromycin
ritonavir) increase domperidone levels/arrhythmia risk; anticoagulants (e.g.
warfarin) may need monitoring; drugs needing acidic pH for absorption (e.g.
ketoconazole
atazanavir
