You can usually treat a simple cold in pregnancy with a mix of safe medicines (like acetaminophen and saline sprays) plus lots of rest, fluids, and non‑drug remedies, but you must avoid certain ingredients such as ibuprofen, naproxen, codeine, and phenylephrine unless your own doctor specifically approves them. Always check with your prenatal provider or pharmacist before starting any medication, especially in the first trimester or if you have other health conditions.

Important safety first

  • Contact your doctor or maternity unit urgently if you have:
    • Fever over 38.0°C (100.4°F), shortness of breath, chest pain, coughing up blood, decreased baby movements, or symptoms lasting more than about 7–10 days.
* Chronic conditions (asthma, heart disease, high blood pressure, diabetes) or you are in the third trimester and feel significantly unwell.
  • Do not start or stop prescription medicines (including inhalers) without medical advice.

Medicines that are usually considered okay

Always follow package directions and keep doses and duration as low/short as possible, after your own provider confirms they are suitable for you.

Pain, headache, mild fever

  • Acetaminophen / paracetamol (Tylenol)
    • Preferred pain and fever medicine in all trimesters when used at standard doses.
* Avoid if you have significant liver disease or allergy, and do not exceed the daily maximum on the label.

Stuffy or congested nose

  • Saline nasal spray or drops (non‑medicated)
    • Safe in all stages of pregnancy; helps thin mucus and relieve congestion.
  • Short‑term decongestant sprays (e.g., oxymetazoline, xylometazoline)
    • Some data suggest short‑term use appears low risk, but they should be used sparingly and only if your clinician agrees, to avoid rebound congestion.
  • Oral decongestants (pseudoephedrine)
    • Often only considered in the second and third trimesters , and only if you do not have high blood pressure, heart disease, or preeclampsia risk; many obstetric providers avoid them entirely in the first trimester.
* Must be cleared with your prenatal provider before use.

Runny nose, sneezing, allergy‑type symptoms

  • First‑generation antihistamines such as diphenhydramine (Benadryl) or chlorpheniramine
    • Commonly cited as compatible with pregnancy when used at usual doses; can cause drowsiness.
* Check with your provider if you have glaucoma, urinary retention, or are on other sedating medications.

Cough

  • Dextromethorphan (often labeled “DM” on bottles)
    • A widely used cough suppressant that appears compatible with pregnancy when used within recommended maximum daily doses.
* Avoid multi‑symptom syrups that also contain alcohol or additional pain relievers unless a clinician reviews them.

Medicines you should generally avoid

These are common cold‑medicine ingredients that are usually not recommended in pregnancy unless a specialist has a very specific reason.

  • NSAIDs such as ibuprofen (Advil, Motrin) and naproxen (Aleve)
    • Not preferred in pregnancy; potential risks increase later in pregnancy (kidney and circulation problems for the fetus, issues with amniotic fluid).
  • Aspirin (ASA) in pain‑relief doses
    • Regular analgesic doses are usually avoided; low‑dose aspirin is different and only used if prescribed for conditions like preeclampsia prevention.
  • Phenylephrine (often in “PE” decongestants)
    • Many obstetric sources list this as medication to avoid because of possible effects on blood vessels and fetal blood flow.
  • Codeine and other opioid cough syrups
    • Typically not recommended because of risks of dependence, respiratory depression, and possible effects on the baby.
  • Combination “everything in one” cold/flu products
    • Increase the chance of taking unneeded ingredients and overdosing on acetaminophen or decongestants; targeted single‑symptom products are safer.

Non‑medicine remedies that help

For many pregnant people, non‑drug measures relieve a big part of the discomfort and carry essentially no fetal risk.

  • Rest and sleep:
    • Go to bed earlier and nap when you can; your immune system is already working harder in pregnancy.
  • Fluids:
    • Warm teas, broths, and plenty of water help thin mucus and prevent dehydration, especially if you have fever or poor appetite.
  • Humidified air:
    • Cool‑mist humidifier or steamy showers can reduce nasal congestion and soothe the throat.
  • Gargling and lozenges:
    • Warm salt‑water gargles can ease sore throat; sugar‑free lozenges without added medicines are generally low risk.
  • Positioning:
    • Elevating your head with extra pillows at night can reduce post‑nasal drip and coughing.

When to call your own clinician

Even for a “simple” cold, pregnancy makes it important to keep your provider in the loop.

  • Call your OB/midwife or primary care clinician if:
    • Symptoms last longer than about a week or suddenly worsen.
* You develop ear pain, sinus pain with thick green/yellow discharge, shortness of breath, wheezing, or chest pain.

* You are unsure whether a specific product (brand‑name syrup, tablet, or spray) is safe. Take a photo of the ingredient label and ask your clinician or pharmacist to review it.
