Medications in Pregnancy: Complete Guide
Once you're pregnant, even familiar over-the-counter medicines can suddenly feel uncertain. The good news is that plenty of common medications are considered safe to use in pregnancy — the key is knowing which ones, and always checking anything new with a pharmacist or GP rather than guessing.
Medicines generally considered safe
- Paracetamol is usually the first-choice painkiller in pregnancy, taken at the lowest effective dose for the shortest time needed.
- Some antibiotics, such as penicillin-based options, are commonly prescribed in pregnancy when a GP judges an infection needs treating — always take the exact course prescribed for you specifically.
- Certain antidepressants can be continued or started in pregnancy under specialist guidance; stopping a mental health medication abruptly can carry its own risks, so this should always be a discussion with your GP or psychiatrist, not a decision made alone.
- Most asthma inhalers are considered safe and important to keep using — poorly controlled asthma is generally riskier for you and your baby than the medication itself.
Medicines to be cautious with
- Ibuprofen and other NSAIDs are generally avoided in pregnancy, particularly from around 30 weeks onwards, unless specifically advised by a doctor.
- Aspirin at standard painkiller doses is usually avoided, though low-dose aspirin is sometimes prescribed by a specialist for specific pregnancy conditions — this is a different use entirely and only under medical supervision.
- Some sleeping tablets and sedatives aren't routinely recommended in pregnancy — speak to your GP about safer alternatives for sleep problems.
- Herbal and "natural" remedies aren't automatically safer just because they're not conventional medicine — some have no safety data in pregnancy at all, so it's worth checking these too.
How to check any medication
- Ask your pharmacist — they can check almost any medicine on the spot and are a fast, free resource.
- Speak to your GP or midwife before starting anything new, and mention your pregnancy at every appointment, including dental and optician visits.
- Never stop a prescribed medication on your own without medical advice, even if you're worried about pregnancy safety — the risks of stopping (for conditions like epilepsy, depression, or high blood pressure) can sometimes outweigh the risks of continuing.
- Keep a note of everything you take, including vitamins and supplements, so you can review the full list with your midwife at antenatal appointments.
Frequently Asked Questions
Can I take paracetamol when pregnant?
Paracetamol is generally considered safe to use in pregnancy at standard doses, and is usually the recommended painkiller of choice. If you find you need it often, mention this to your GP so they can check for an underlying cause.
Can I take ibuprofen when pregnant?
Ibuprofen and similar anti-inflammatory painkillers are generally avoided in pregnancy, especially in the later stages, unless a doctor has specifically told you to take it. Paracetamol is the usual first choice instead.
What should I do if I took a medication before I knew I was pregnant?
Try not to panic — many pregnancies are unplanned and short exposures before a positive test are common. Contact your GP or midwife, tell them exactly what you took and when, and they can advise whether any follow-up is needed.
