When you take a half tablet of a 1000 mg (milligrams) powered medication, you are effectively taking 500 mg of the active ingredient. This is because the tablet is specifically designed to be split in half, and each half contains an equal amount of the active ingredient.
The reason it works this way is that the manufacturer ensures that the medication is evenly distributed throughout the tablet. So, if the full tablet contains 1000 mg, half of the tablet will contain half of that amount, which is 500 mg.
It's important to note that not all medications are suitable for splitting, as some may have an uneven distribution of the active ingredient or have a special coating that helps with controlled release. If you are considering splitting tablets to adjust the dosage, it's crucial to consult your healthcare provider or pharmacist first to ensure that it's safe and appropriate for the specific medication you are taking. They can provide guidance on proper dosing and whether splitting the tablets is suitable for your situation.
