This is a very well-documented evolution in India's national programme. Here is the complete explanation:
Why Some Textbooks Say 100 mg and Others Say 60 mg
The Short Answer: It Changed Over Time
The dose was 100 mg elemental iron under the older National Nutritional Anaemia Prophylaxis Programme (NNAPP) and the National Iron Plus Initiative (NIPI). It was officially revised down to 60 mg under Anaemia Mukt Bharat (AMB, 2018). Textbooks written before or during the NIPI era still carry 100 mg, while AMB-era materials use 60 mg.
Timeline of the Change
| Era | Programme | Dose for Pregnant Women | Duration |
|---|
| 1970 - 2000s | NNAPP (National Nutritional Anaemia Prophylaxis Programme) | 60 mg elemental iron + 500 mcg FA | 100 days |
| 2013 | NIPI (National Iron Plus Initiative) | 100 mg elemental iron + 500 mcg FA | 180 days |
| 2018 onwards | AMB (Anaemia Mukt Bharat) | 60 mg elemental iron + 500 mcg FA | 180 days |
So the sequence was: 60 mg (NNAPP) → 100 mg (NIPI 2013) → back to 60 mg (AMB 2018).
Why Was It Changed to 100 mg in NIPI (2013)?
The National Iron Plus Initiative (2013) increased the dose to 100 mg based on the reasoning that India's anaemia burden was severe and higher iron doses would correct deficiency faster. The NIPI also extended the duration from 100 days to 180 days simultaneously.
Park's textbook (older editions) and some state NHM documents still reflect the NIPI 2013 recommendation of 100 mg, which is why many students encounter this figure.
Why Was It Switched Back to 60 mg in AMB (2018)?
The AMB operational guidelines explicitly state this as one of their key programme changes. The AMB Training Module lists it directly:
"Switch from 100 mg to 60 mg elemental iron in prophylactic dose of elemental iron for women and adolescents."
The rationale for this reversal:
- Side effects increase with higher iron doses - nausea, epigastric discomfort, constipation, and diarrhoea are worse with 100 mg. This was a major driver of poor compliance.
- WHO recommendation is 60 mg/day - the global standard for prophylaxis in pregnant women is 60 mg daily, and 120 mg only for treatment of anaemia.
- Compliance over completeness - 60 mg for 180 days delivers more total iron with better adherence than 100 mg tablets that women stop taking due to side effects.
- Evidence on free radical damage - higher iron doses increase oxidative stress and intestinal epithelial damage.
What Remains 100 mg?
Even under AMB, 100 mg tablets still exist for:
- Adolescents 10-19 years under NIPI: some older state-level documents still list 100 mg weekly for adolescents
- Therapeutic dose: 2 x 60 mg tablets = 120 mg daily for anaemic pregnant women (which effectively approximates prior therapeutic doses)
Exam Guidance
| Exam Context | Use This |
|---|
| Older Park's / NIPI-era MCQs | 100 mg elemental iron, 100 days |
| AMB / current NHM / post-2018 MCQs | 60 mg elemental iron, 180 days |
| WHO recommendation | 60 mg daily prophylaxis |
| Treatment of anaemia (AMB) | 2 tablets x 60 mg = 120 mg daily |
When an exam question says "current national programme" or "Anaemia Mukt Bharat," the answer is 60 mg + 500 mcg folic acid, daily, for 180 days. If it says "NIPI" or references the 2013 guidelines, the answer is 100 mg.
