The recommended dosage of Gastromark is 600 mL (105 mg Fe) administered orally at a rate of about 300 mL over 15 minutes. The maximum oral dose is 900 mL (157.5 mg Fe).
Gastromark should be taken after fasting at least 4 hours.
Before use, the bottles should be shaken vigorously for at least 1 full minute to assure uniform suspension of contents. Chilling before ingestion improves palatability. Any unused portion should be discarded.
Gastromark contains 175 μg iron per milliliter. The amount of iron absorbed varies with the patient’s iron stores (see CLINICAL PHARMACOLOGY section).
Imaging: After ingestion of Gastromark, imaging may begin immediately. Generally, optimal results occur within 30 minutes. In some patients, delayed images (4 to 7 hours after ingestion) may be useful in delineating the lower gastrointestinal regions.
