Community pharmacists support women at every stage of pregnancy — from preconception planning through to postnatal recovery. This guide brings together the key pharmacy-relevant topics across the pregnancy journey, with links to detailed articles on each subject.
Before pregnancy: preconception
The most important pharmacy intervention in pregnancy happens before conception. Folic acid supplementation, ideally started at least 12 weeks before conception and continued through the first 12 weeks of pregnancy, reduces the risk of neural tube defects by approximately 70% according to Cochrane review data. The standard dose is 400 micrograms daily, rising to 5mg daily for women with diabetes, BMI over 30, previous neural tube defect-affected pregnancy, or taking antiepileptic medicines.
Pharmacists are often the first healthcare professional a woman consults when planning a pregnancy. Key preconception advice includes:
- Folic acid — start before conception. See the detailed guide: Folic Acid Before and During Pregnancy
- Smoking cessation — refer to the NHS quit support programme
- Medication review — flag any medicines that may need switching (e.g. ACE inhibitors, statins, retinoids, valproate)
- Vaccination status — check rubella immunity and varicella history
First trimester
Pregnancy testing and early advice
Pharmacy pregnancy testing services provide the opportunity for early counselling — not just confirming the result, but advising on booking an NHS midwife appointment, folic acid, alcohol avoidance and which medicines are safe to continue. See: Pregnancy Testing at the Pharmacy
Nausea and vomiting
Affecting up to 80% of pregnancies, nausea and vomiting in pregnancy (NVP) is one of the most common reasons pregnant women visit a pharmacy. First-line options include ginger, acupressure bands and — where symptoms are more severe — cyclizine or promethazine on prescription. See: Nausea and Vomiting in Pregnancy
Supplements beyond folic acid
The supplement market promotes dozens of "pregnancy vitamins", but the evidence supports only a few. Vitamin D (10 micrograms daily throughout pregnancy) is recommended by NICE. Iodine, omega-3 and other supplements have weaker or absent evidence for routine use. See: Antenatal Vitamins Beyond Folic Acid
Second and third trimester
Iron supplementation
Iron deficiency anaemia affects approximately 25% of pregnancies in the UK. Ferrous sulfate 200mg twice daily is the standard first-line treatment, but tolerability varies — and the evidence now supports alternate-day dosing for better absorption. See:
Heartburn and reflux
Gastro-oesophageal reflux affects up to 80% of women in the third trimester. Antacids and alginates (particularly Gaviscon) are first-line and safe in pregnancy. PPIs (omeprazole) may be used when symptoms are severe. See: Heartburn in Pregnancy
Constipation
Progesterone-mediated gut slowing and iron supplementation both contribute to constipation in pregnancy. Ispaghula husk and lactulose are first-line; stimulant laxatives should be avoided. See: Constipation in Pregnancy
Pain relief
Paracetamol remains the analgesic of choice in pregnancy. The 2021 consensus statement raising concerns about paracetamol in pregnancy was subsequently critiqued for methodological limitations, and both NICE and the RCOG continue to support its use at standard doses when needed. NSAIDs are contraindicated from 20 weeks. See: Paracetamol in Pregnancy
Gestational conditions
Two conditions require particular pharmacy awareness:
Gestational diabetes affects approximately 5% of pregnancies and is rising with increasing maternal age and BMI. Pharmacy teams support blood glucose self-monitoring and metformin/insulin dispensing. See: Gestational Diabetes
Gestational hypertension and pre-eclampsia are leading causes of maternal morbidity. Low-dose aspirin (75–150mg) is recommended from 12 weeks for women at increased risk. Pharmacists should know the red-flag symptoms. See: Gestational Hypertension and Pre-eclampsia
Infections and skin conditions
UTIs in pregnancy are excluded from Pharmacy First (they require GP or midwife management due to the risk of pyelonephritis and preterm labour). See: UTI in Pregnancy: Why Pharmacy First Does Not Apply
For fungal skin infections, the safe topical antifungal options differ from the general population. See: Pregnancy-Safe Topical Antifungals
After birth: postnatal care
Safe medicines while breastfeeding
The question "can I take this while breastfeeding?" is one of the most common postnatal pharmacy queries. Most common OTC medicines are compatible with breastfeeding, but the evidence base is often sparse. The LactMed database and the UK Drugs in Lactation Advisory Service (UKDILAS) are authoritative sources. See: Breastfeeding and Medicines
Postnatal depression
Affecting approximately 10–15% of new mothers, postnatal depression is underdiagnosed. Pharmacy teams may notice changes in a patient's presentation, missed prescription collections, or direct disclosures. See: Postnatal Depression: Pharmacy Awareness
Contraception after birth
Fertility can return as early as 21 days postpartum. The progestogen-only pill (including desogestrel, available OTC) is compatible with breastfeeding. Combined hormonal methods are avoided until 6 weeks postpartum (or 6 months if breastfeeding) due to thrombotic risk. See: Postnatal Contraception
The pharmacy team's role across pregnancy
| Stage | Key pharmacy actions |
|---|---|
| Preconception | Folic acid counselling, medication review, smoking cessation referral |
| First trimester | Pregnancy test advice, NVP management, supplement guidance |
| Second/third trimester | Iron monitoring, heartburn/constipation management, gestational condition support |
| Postnatal | Breastfeeding medicines advice, mental health awareness, contraception |
