Preconception Counseling
Current Guidance Update
Folic Acid Supplementation
Women should begin taking folic acid 400mcg daily at least one month before conception, with three months being preferable. High-risk women should receive 5mg daily.
Comprehensive Preconception Care
Preconception care should include assessment of medical conditions, medications, lifestyle habits, immunisation status, and genetic risk factors before pregnancy.
Improving Pregnancy Outcomes
Preconception care is recognized as one of the highest-yield interventions for improving both maternal and neonatal health outcomes worldwide.
Diabetes Optimisation
Women with diabetes planning pregnancy should aim for an HbA1c below 48 mmol/mol before conception to reduce pregnancy complications.

What Preconception Counseling Covers
- Medical history and chronic condition review
- Medication review to discontinue teratogens

Folic Acid
Taking 400mcg of folic acid daily, ideally starting 3 months before conception, reduces the risk of neural tube defects by approximately 70%. Women with additional risk factors should receive 5mg daily.
Optimisation Before Pregnancy
- Diabetes – HbA1c ideally below 48 mmol/mol
- Thyroid disease – TSH below 2.5 mIU/L
- Hypertension – switch to pregnancy-safe medications
- Epilepsy – monotherapy at the lowest effective dose; avoid valproate
- Autoimmune disease – assess stability and continue hydroxychloroquine in SLE when appropriate
Genetic Considerations
- Haemoglobinopathy screening in high-risk populations
- Cystic fibrosis carrier screening where available
- Referral for genetic counseling when family history suggests inherited conditions
Frequently Asked Questions
How long before trying to conceive should I start folic acid?
Ideally 3 months before, to optimise tissue folate levels at the critical period of neural tube closure.
Is preconception counseling only for women with health conditions?
No — all women planning pregnancy benefit from supplementation guidance, vaccination review, and lifestyle optimisation.
Conclusion
Preconception counseling is medicine's most proactive investment in maternal and child health, providing an unmatched opportunity to optimise conditions for a healthy pregnancy.
