3 Proper Usage

To use Probucol properly, you must follow all instructions given by your doctor.

Here are some points to watch for:

  • Strictly follow your doctor and don’t miss any dose or take higher doses unless suggested by your doctor.

  • Taking probucol with meals can enhance drug efficiency.
  • In many cases, high cholesterol problems may be managed with a combination of exercise and a low-fat diet. If this does not work, then only medicine is added to this combination.
  • Being overweight makes this drug less effective.
  • Always consult your doctor before following a diet plan especially that with low-sodium and low-sugar.


For best results, follow your doctor to know what amount of medicine you should take in a single dose. The doses of a medicine can differ according to the conditions for which it is being prescribed. The doses of tablets are:

  • Children up to 2 years: Not recommended.
  • For children 2 years and above: Your doctor will decide the dose.

Take your missed dose once you remember but avoid it if it’s time to take your next dose, and follow your normal dosing schedule. Avoid taking double doses to make up for the missed dose. 


  • Store in a closed container at room temperature.
  • Keep away from heat, moisture, and direct light.
  • Do not freeze.
  • Keep away from children.
  • Discard any unused or expired medicines.
