  2. Take 1 tablet in the morning and,
  3. Take 1 tablet mid-afternoon to control your symptoms throughout the day.

Your doctor or healthcare professional may adjust the dosing schedule according to your condition.

Do not stop taking DICLECTIN on your own. Always consult your doctor or healthcare professional. They will gradually reduce your dose when stopping DICLECTIN treatment to prevent a sudden return of nausea and vomiting.

In case of drug overdose, contact a healthcare practitioner, hospital emergency department or regional Poison Control Centre immediately, even if there are no symptoms.

If you suspect an accidental overdose, seek medical attention immediately. Do not wait for any signs or symptoms to appear before seeking medical attention, as they may not occur immediately.
