Iron supplements can sometimes cause tummy upsets and constipation. Although while taking Spatone this is unlikely, should problems occur tell your healthcare professional (e.g. Doctor, Pharmacist, Midwife). They may suggest you try a combination of the following steps:
Dilute Spatone in water or fruit juice.
Spatone is ideally taken in the morning on an empty stomach diluted in orange juice. Please allow at least 30 min or better one hour before having e.g. coffee or tea, or eating breakfast.
