You have a headache, a cold, or a fever. But you are breastfeeding your baby, so you are scared to take any medicine. What if it harms your baby through breast milk?
This fear is very common among Indian mothers. Many women suffer through pain and illness without taking medicine, or worse, they stop breastfeeding because they think they have to choose between medicine and feeding their baby.
Here is the good news: most common medicines are safe while breastfeeding. Only a small number of medicines need to be avoided. This guide will help you understand which medicines are safe, which ones to avoid, and how to take them wisely.
Medicines That Are Safe While Breastfeeding
These common medicines have been well-studied and are considered safe for breastfeeding mothers. Only very small amounts pass into breast milk, and they do not harm the baby.
For Pain and Fever
- Paracetamol (Crocin, Dolo, Calpol) — This is the safest painkiller for nursing mothers. Very little passes into breast milk.
- Ibuprofen (Brufen, Ibugesic) — This is actually the preferred painkiller for breastfeeding women. It has the lowest transfer into breast milk among all common painkillers. It also works well for body pain, cramps, and inflammation.
For Infections (Antibiotics)
- Amoxicillin — Very commonly prescribed for throat infections, urinary infections, and ear infections. Safe while breastfeeding.
- Cephalexin (Cefalexin) — Another safe antibiotic, often used for skin infections and urinary infections.
- Azithromycin (Azee, Zithromax) — Safe for breastfeeding mothers. Commonly prescribed for respiratory infections.
For Allergies and Cold
- Cetirizine (Cetzine, Okacet) — Safe antihistamine for allergies, sneezing, and runny nose. It causes less drowsiness than older antihistamines.
- Loratadine (Lorfast, Claritin) — Another safe antihistamine. Very little passes into breast milk.
Other Safe Medicines
- Omeprazole, pantoprazole (for acidity) — Safe in normal doses.
- Insulin (for diabetes) — Does not pass into breast milk at all.
- Thyroid medicine (levothyroxine) — Safe and important to continue.
- Iron and calcium supplements — Safe and often needed after delivery.
Medicines to Avoid While Breastfeeding
Some medicines can be harmful to your baby through breast milk. These should be avoided unless your doctor says otherwise:
- Codeine and tramadol — These are strong painkillers. They can cause serious problems in the baby, including slow breathing (respiratory depression) and extreme sleepiness. Some babies have died from codeine passed through breast milk. If you need strong pain relief, ask your doctor for safer options.
- High-dose aspirin — Low-dose aspirin (75 mg) is generally safe, but high doses can be harmful to the baby. Use paracetamol or ibuprofen instead.
- Tetracycline and doxycycline (long-term use) — These antibiotics can affect the baby's bone and teeth development if used for more than 3 weeks. Short courses (less than 3 weeks) are considered acceptable.
Medicines That Need Caution
Some medicines are not completely unsafe, but they need careful discussion with your doctor:
Metronidazole (Flagyl, Metrogyl)
This is a common antibiotic used for dental infections, stomach infections, and vaginal infections. It does pass into breast milk and can give the milk a bitter taste. For a single high dose, some doctors recommend pumping and discarding your breast milk for 12 to 24 hours. For regular doses, many experts consider it safe to continue breastfeeding. Ask your doctor what is best for your situation, or whether an alternative antibiotic can be used.
Benzodiazepines (Alprazolam, Diazepam)
These are medicines for anxiety and sleep. They can make your baby very sleepy and drowsy. If you need these medicines, your doctor may prescribe a shorter-acting one at the lowest possible dose. Do not take these without your doctor's knowledge while breastfeeding.
Antidepressants
Postpartum depression is real and needs treatment. The good news is that some antidepressants, such as sertraline (Zoloft) and paroxetine, are considered safe during breastfeeding because very little passes into the milk. If you are struggling with low mood, anxiety, or depression after delivery, please talk to your doctor. Do not suffer in silence, and do not avoid treatment because you are breastfeeding.
Timing Tip: Take Medicine Right After Feeding
Here is a simple trick that works for most medicines: take your medicine right after you finish breastfeeding your baby. This gives the medicine the maximum time to clear from your body before the next feed.
Most medicines reach their highest level in your blood (and breast milk) about 1 to 3 hours after you take them. By the time your baby feeds again (usually 2 to 4 hours later), the medicine level in your milk will be lower.
This timing trick is not necessary for very safe medicines like paracetamol, but it is a good habit to follow when you are taking any medicine you are unsure about.
Always Tell Your Doctor and Pharmacist
Whenever you visit a doctor or buy medicine from a pharmacy, always mention that you are breastfeeding. This is important because:
- Your doctor can choose a breastfeeding-safe medicine from the start.
- Your pharmacist can double-check if the prescribed medicine is safe for nursing mothers.
- Many doctors forget to ask, so it is your responsibility to tell them.
This applies to all visits — not just your gynecologist. If you go to a dentist, a skin doctor, or even a general physician for a cold, tell them you are breastfeeding.
LactMed: A Free Tool to Check Any Medicine
If you want to check whether a specific medicine is safe while breastfeeding, there is a free and reliable database called LactMed. It is run by the U.S. National Institutes of Health (NIH).
If In Doubt: Do Not Stop Breastfeeding
This is the most important message of this article. If you are unsure whether a medicine is safe, do not stop breastfeeding. Instead:
- Call your doctor and ask for a breastfeeding-safe alternative.
- Check the medicine on LactMed.
- Ask your pharmacist.
- If none of these are possible right away, it is usually safer to continue breastfeeding than to stop suddenly. Most medicines pass into breast milk in very small amounts.
Breast milk gives your baby nutrition, immunity, and protection from infections. The benefits of breastfeeding almost always outweigh the small risk from most medicines.
