Cold Remedies in Pregnancy: What's Safe?
A blocked nose, sore throat, and general fogginess feel worse in pregnancy — partly because your immune system works differently, and partly because your usual go-to medicine cabinet reach might not be appropriate anymore. The good news is that most common colds in pregnancy can be managed safely and comfortably with a mix of approved medicines and simple home remedies.
What's generally considered safe
Standard advice from UK pharmacists and midwives is that these options are usually fine for treating cold symptoms in pregnancy, though it's always worth confirming with your pharmacist or GP first, especially in the first trimester or if you take other medication:
- Paracetamol, at the standard adult dose, for aches, headache, or a raised temperature
- Saline nasal sprays or rinses, which relieve congestion without any medication at all
- Steam inhalation (being careful of burns) to ease a blocked nose
- Throat lozenges that don't contain added decongestants
- Honey and lemon in warm water for a sore throat and cough — not suitable for babies, but fine for you
- Plenty of fluids and rest, which sound basic but genuinely help recovery
What to avoid or check first
Some ingredients found in everyday cold and flu products are best avoided, particularly in the first trimester when the baby's organs are forming:
- Ibuprofen and other NSAIDs — generally avoided throughout pregnancy unless specifically advised by a doctor, and particularly avoided from 30 weeks onwards due to risks to the baby
- Decongestants such as pseudoephedrine and phenylephrine — most guidance recommends avoiding these, especially in the first trimester, due to a possible link with reduced blood flow to the placenta
- Combination cold and flu tablets — these often bundle several active ingredients together (a painkiller plus a decongestant plus something else), making it harder to know exactly what you're taking and in what dose
- Aspirin — not recommended in pregnancy except in specific circumstances directed by a doctor (such as low-dose aspirin for certain pregnancy complications)
If you're ever unsure whether an over-the-counter product is safe, ask your pharmacist directly — they can check the exact ingredients against current pregnancy guidance far more precisely than a product's marketing copy or box label.
When to see a doctor
Most colds clear up within a week to ten days with simple self-care. Contact your GP or midwife if:
- Your temperature is high (generally above 37.5°C) and doesn't settle with paracetamol
- Symptoms last much longer than usual or get significantly worse rather than better
- You develop chest pain, breathlessness, or a persistent cough
- You feel generally unwell in a way that worries you, even if you can't pinpoint why
A fever in pregnancy is worth taking seriously and getting checked, since your body's response to infection is slightly different when pregnant, and prompt paracetamol plus medical advice is the safest combination.
Frequently Asked Questions
Can I take cold and flu tablets when pregnant?
It's best to avoid combination cold and flu tablets, since they often contain decongestants like pseudoephedrine that aren't recommended, particularly in the first trimester. Stick to plain paracetamol for aches and fever, and use natural remedies such as honey, lemon, and saline sprays for congestion. Check with your pharmacist if you're unsure about any specific product.
How do I treat a cold naturally in pregnancy?
Rest, fluids, saline nasal sprays or rinses, steam inhalation, and honey and lemon in warm water are all considered safe and effective ways to ease cold symptoms without medication. These won't cure a cold faster, but they can make the days you're feeling rough more bearable while your immune system does the work.
Is it safe to take paracetamol for a cold while pregnant?
Yes, paracetamol at the standard recommended dose is generally considered the safest choice of painkiller and fever-reducer throughout pregnancy, and it's the option most commonly recommended by midwives and pharmacists for cold-related aches or a raised temperature. Always follow the dosing instructions on the packet and don't exceed the maximum daily amount.
