From the Guidelines
Iron tablets should be taken once a day at most, with every-other-day iron dosing being a suitable alternative for some patients who experience better tolerance with similar or equal rates of iron absorption as daily dosing. When taking iron tablets, it is essential to consider the timing and formulation to maximize absorption and minimize side effects.
- Ideal timing for taking iron tablets is on an empty stomach with water or juice, 1-2 hours before meals or 2 hours after eating, as this allows for maximum absorption 1.
- Taking iron supplements with vitamin C (like orange juice) can enhance absorption, but it is crucial to avoid taking them with calcium supplements, antacids, coffee, tea, or dairy products, which can reduce effectiveness 1.
- Common dosages range from 65-325 mg of elemental iron, and the specific dose and formulation should be determined based on individual needs and doctor's recommendation 2.
- Side effects such as constipation, black stools, and stomach upset can be minimized by starting with a lower dose and gradually increasing it, taking the supplement with a small amount of food if necessary, or switching to a different formulation like ferrous gluconate which may be gentler on the stomach 1.
- Iron supplements are typically taken for 3-6 months to restore iron levels, but the duration of treatment should be guided by healthcare provider's recommendations and regular monitoring of hemoglobin levels 2.
- It is also important to note that the optimal drug, dosage, and timing of oral iron replacement therapy (IRT) for adults with iron deficiency anemia (IDA) are not clearly defined, and individualized treatment plans should be developed based on patient-specific factors and response to treatment 2.

From the Research
Iron Tablet Administration
There are no research papers to assist in answering this question, as the provided study 4 discusses the total condylar knee prosthesis and its application in knee deformities, with no mention of iron tablets or their administration.
Relevant Information
- The study 4 focuses on the outcomes of 220 arthroplasties in 183 patients, with follow-up times ranging from three to five years.
- The report discusses the assessment of patients using The Hospital for Special Surgery scoring system, with 62% of knees rated as excellent and 28% rated as good.
- Complications and reoperation rates are also discussed in the study 4, but none of this information is relevant to the administration of iron tablets.
