Can you drink alcohol based syrups while pregnant?

If a syrup contains alcohol, whether it is suitable during pregnancy depends on the specific product, its ingredients and why you are taking it. It is not a good idea to assume that every alcohol-containing syrup is safe, or that it should automatically be avoided if it is a medicine you need.

UK guidance recommends avoiding alcoholic drinks during pregnancy because there is no proven safe level of alcohol exposure. Medicines are a separate question. The NHS advises checking any medicine with a pharmacist, midwife or GP before taking it during pregnancy, including medicines bought from a pharmacy or shop.

So if you have a cough syrup, herbal preparation, tonic or another liquid product that lists alcohol or ethanol, check the exact product with a healthcare professional rather than trying to judge it from the alcohol content alone.

Why do some syrups contain alcohol?

Alcohol, often listed as ethanol, can be used as an ingredient in some liquid preparations. A syrup may also contain several active and inactive ingredients, which means alcohol is not necessarily the only pregnancy consideration.

This matters because two products that look similar on the shelf may have different formulations.

For example, cough and cold syrups can contain different active medicines. Herbal liquid products may contain plant ingredients as well as alcohol. A pharmacist can look at the complete ingredient list and advise whether the particular product is appropriate during pregnancy.

The NHS recommends checking with a pharmacist, midwife or GP before taking any medicine while pregnant. This applies to prescribed medicines as well as products bought without a prescription.

Is the alcohol in a syrup the same as drinking alcohol?

Alcohol in a medicinal or herbal liquid is still alcohol, but the amount you are exposed to depends on the product and how it is used.

That is why it is not useful to treat every alcohol-containing syrup as equivalent to having a glass of wine or another alcoholic drink. Equally, a small serving size does not prove that a particular syrup is suitable during pregnancy.

UK pregnancy guidance is clear that the safest approach is not to drink alcoholic beverages during pregnancy. The NHS states that drinking alcohol during pregnancy can harm a developing baby and that there is no proven safe level.

For a medicine or syrup, however, the decision needs to take account of the whole product. The medicine itself, the reason it is needed and the available alternatives may all matter.

What should you check on the label?

If you have a syrup at home, start by checking its packaging and patient information leaflet.

Look for the exact product name and active ingredients. Alcohol may appear on the ingredient list as alcohol or ethanol. Some labels also state how much ethanol a serving contains.

Do not rely only on words such as “natural”, “herbal” or “traditional”. The NHS advises that not all natural or complementary remedies are safe during pregnancy.

It can help to take the bottle, box or a clear photograph of the label to a pharmacist. That gives them the exact formulation to check rather than only a general product category.

What about cough syrups containing alcohol?

Cough syrups vary considerably, so there is no single pregnancy answer that applies to every bottle.

Some contain medicines for suppressing a cough or loosening mucus. Others contain antihistamines, decongestants, herbal ingredients or combinations of several substances. Some formulations may also contain ethanol.

If you are pregnant and considering a cough syrup, ask a pharmacist, midwife or GP to check the exact product before taking it. They can consider all of its ingredients, not only the alcohol.

If you have already taken a cough medicine, do not assume that this means there is a problem. Keep the packaging and ask a healthcare professional about the particular product and the amount you took.

What about herbal syrups and tinctures?

Herbal does not automatically mean pregnancy-safe.

Some herbal preparations are supplied as syrups, tinctures, drops or tonics and may contain alcohol. They can also contain herbs for which pregnancy safety information is limited.

The NHS advises telling your midwife, doctor or pharmacist if you use herbal or homeopathic remedies. It also notes that not all natural remedies are safe during pregnancy.

If a herbal product contains alcohol, both the alcohol and the other ingredients need to be considered. Checking the exact formulation is more useful than relying on the product being marketed as natural.

Should you stop a prescribed syrup because it contains alcohol?

Do not stop a prescribed medicine simply because you notice alcohol on the ingredient list without first speaking to the healthcare professional responsible for your treatment.

The NHS specifically advises not to stop prescribed medicines during pregnancy without checking with a doctor. Stopping a medicine that is keeping you well can itself be harmful.

If you are concerned about an alcohol-containing formulation, ask whether the medicine is suitable during pregnancy and whether another formulation is available. The right answer depends on the medicine and your individual circumstances.

What if you have already taken an alcohol based syrup?

If you took a syrup before noticing that it contained alcohol, there is no benefit in trying to estimate the pregnancy risk from the word “alcohol” on the label alone.

Keep the packaging and note the product name, ingredients and how much you took. A pharmacist, midwife or GP can use that information to give you more relevant advice.

UKTIS’s patient information service, BUMPS, also provides evidence-based information about medicines and other exposures during pregnancy. The NHS recommends BUMPS as a source of information about medicines in pregnancy.

For alcohol exposure more generally, RCOG states that although there is no safe level of alcohol recommended during pregnancy, the risk of harm is low with small amounts consumed before someone knows they are pregnant. That guidance should not be used to decide whether a particular medicine is suitable, but it can provide context if accidental alcohol exposure is causing anxiety.

When to get professional advice

Check with a pharmacist, midwife or GP before taking an alcohol-containing syrup, particularly if it is a medicine, herbal preparation or product with several active ingredients.

If you have already taken a product and are concerned, tell them the exact name, ingredients and amount taken. Do not stop a medicine that has been prescribed for you without first speaking to your doctor or another appropriate healthcare professional.

Seek medical advice if you are unwell and are unsure how to manage your symptoms safely during pregnancy. Your pharmacist, GP or maternity team can advise on suitable options.

For urgent pregnancy or health concerns, contact your maternity unit, GP or NHS 111 as appropriate. Call 999 or go to A&E for a life-threatening emergency.
