How Should You Take Loratadine?

How much loratadine is safe to take? You already know the answer, and then how should you take it?

  • Loratadine must be taken as prescribed in the product label or by your doctor. Usually a single dose once a day is enough. Do not take more of the indicated dosage or for more times than prescribed.
  • Under no circumstances should you give loratadine or any cold or cough syrup to a child under 2 years of age, unless strictly prescribed by a doctor. Failing to do so can lead to serious health issues and even death of the infant.
  • The regular oral tablet must be consumed entirely, without breaking or chewing it. For the one with liquid presentation, you must carefully measure the dosage with a syringe or a special medicine cup. With a chewable tablet, you need to chew very well before swallowing it and do not take the tablet as a whole. In the case of the disintegrating tablet (Alavert, Claritin RediTab) you need to handle the tablet with precaution to avoid breaking it or getting it wet. Peel back the foil of the package instead of pushing the tablet through it, keep your hands dry, and allow the tablet to slowly disintegrate in your mouth.
  • Always keep the drug package in a dry place and away from heat.
  • Call your doctor if the symptoms persist or get worse after having correctly taken the drug.
