Pregnant and asking for a painkiller: preparing the answer without letting AI give it

Reading time: about 11 minutes

This is one of the queries where a pharmacist adds most value and where a quick answer can do most harm. The right information exists and has been reviewed — on this site, in the pregnancy and breastfeeding tool, with its source alongside — but her question has a catch: "paracetamol is doing nothing" pushes towards an anti-inflammatory, and whether that is possible depends on something she has not said. AI can help you not to forget questions. What it cannot do is answer for you.

Step by step

1. Before thinking about the medicine, ask the week

   The first question is not what to give her, but how many weeks pregnant she is. For pain relief in pregnancy, the trimester changes the answer completely, and for anti-inflammatories there is a precise line: the Spanish medicines agency, in its 2020 safety note, advises avoiding ibuprofen from week 20 because of the risk of oligohydramnios and premature closure of the ductus arteriosus. Before that week, only if essential, at the lowest dose and for the shortest time possible.

   In other words: her question — "something stronger than paracetamol" — cannot be answered without that information, and there is no way to work it out by looking at her.

   The second question is about the pain itself: since when, what it is like, whether it is different from her usual headaches, whether anything else comes with it. A new, severe headache in the second half of pregnancy is not a painkiller query: it is a referral, and that is your decision, one no chat can make.

2. Use AI to prepare the questions, not the answer

   Where AI does help is in making sure you forget nothing with a queue behind her. Ask it for a list of interview questions, not a recommendation. With nobody’s data: it is a template you can use for any pregnant customer.

   I am a community pharmacist in Spain. Prepare a list of 8 SHORT
   questions to ask at the counter of a pregnant woman who is asking for a
   painkiller for a headache and says paracetamol is not working.
   
   The questions should help me:
   - find out the week of pregnancy,
   - spot signs that mean referring her to a doctor or to A&E,
   - find out how she has taken the paracetamol (dose, frequency, days),
   - find out what else she is taking.
   
   Do NOT recommend any medicine. Only the questions, ordered from most
   to least urgent.

   The instruction not to recommend anything matters. Without it, the model mixes the questions with a treatment suggestion, and the suggestion is what sticks in your head.

3. Look at how she has taken the paracetamol

   "It is doing nothing" often means "I took one yesterday afternoon". Before concluding that paracetamol does not work, find out what dose she took, how often and for how many days. In this site’s pregnancy and breastfeeding tool, paracetamol is listed as first choice in any trimester, at standard therapeutic doses: up to 4 g a day, and no more than 2 g a day if there is liver disease.

   Sometimes the answer to the query is simply explaining how to take it properly. And sometimes the important information is the opposite: if she has been taking the maximum dose for days and the pain is not easing, that too is a reason for a doctor to see her, not for you to move up a step on your own.

   Ask about combination products as well. Many cold remedies and some painkillers contain paracetamol, and adding them together is the most common way of going over the limit without knowing it.

4. The information comes from the reviewed source, not the chat

   With the week and the history of the pain, you can decide. And the information to decide with comes from the pregnancy and breastfeeding tool or the SmPC, not from a chat reply. In that tool, each medicine has a traffic light per trimester and its source written out: for ibuprofen, the 2020 safety note; for metamizole, avoid in the first and third trimesters and in the second only if paracetamol or an NSAID do not control the pain, with the 2018 note.

   Notice why the source matters more here than anywhere else: recommendations on medicines in pregnancy change with safety notes, and a model trained on texts from before a note does not know it exists. It will give you the old recommendation in the same tone as the current one.

   If what she needs cannot be solved with paracetamol taken properly, the decision to use something else belongs to the doctor or midwife looking after her pregnancy. Your role is to refer, with the information organised.

5. Prepare the explanation, and the message for the doctor if needed

   Here AI is useful again, always on the basis of what you have already decided. If the conclusion is to take paracetamol properly, ask it for a clear explanation in a few lines using the dosing you give it. If the conclusion is to refer, ask it to help you word two sentences for her explaining why, without alarming her.

   Write 4 lines explaining calmly to a pregnant woman why it is
   better to check with her doctor or midwife before taking any painkiller
   other than paracetamol. Do not name any medicine as an alternative.
   Do not give doses. Do not use alarming words.

   And note down what you checked: the week, the paracetamol dose she was taking and the reason for referral. If she comes back, or the doctor calls, you have it.

A full example, and what is wrong with it

This is what a model replied to "I’m pregnant and paracetamol isn’t shifting my headache, what can I take?", which is literally what the customer would have typed if she had asked the chat herself. It is shortened and not polished.

And now, what is wrong with that reply:

1. The ibuprofen cut-off is wrong. "Preferably avoiding the third trimester" is the old advice. The 2020 safety note brings it forward to week 20, which is in the middle of the second trimester. A woman 24 weeks pregnant reading that reply would understand she can take it — the exact opposite of what the source says.
2. Metamizole is not "another safe option". In this site’s tool — and in its source — it is "avoid" in the first and third trimesters, and in the second only if paracetamol or an NSAID do not control the pain, because of the risk of maternal agranulocytosis. Presenting it as safe and very effective is how you get someone asking for it at the counter in those exact words.
3. It did not ask the week. The whole reply depends on it and it never asks. It answers as if pregnancy were a single nine-month state, which is exactly what it is not where a painkiller is concerned.
4. "See your doctor if it lasts more than a few days" comes too late. A headache that does not respond to paracetamol, has lasted days and occurs in pregnancy may be one that needs assessing now, depending on what it is like and the week. The cautious advice at the end suits a cold, not this.

Four failures, and the first two have an official source against them, one click away on this very site. It is not that the model knows nothing about pregnancy: it knows what many texts said before the latest safety notes, and says it with the same confidence as if it were current.

That is why step 2 asks it for questions, not answers. The questions it prepares are nearly always good — the week, blood pressure, blurred vision, how much paracetamol she has taken — and when one is missing, you notice, because the interview is your territory.
