Adalat LA 30 contains 9.4 mg of sodium (main component of cooking/table salt). This is less than 1 mmol sodium (23 mg) per tablet, that is to say essentially ‘sodium-free’. Increasing the daily dose to 90 mg nifedipine results in an intake of 28.2 mg sodium. This is equivalent to 1.41 % of the recommended maximum daily dietary intake of sodium for an adult. Tell your doctor if you are on a low-salt diet.
