Chloraseptic spray, which contains phenol as its active ingredient, is one of the most commonly recommended throat sprays for pregnant women. Several OB/GYN practices include it on their approved medication lists for sore throat relief during pregnancy. But the answer isn’t quite as simple as grabbing the first bottle you see, because throat sprays vary widely in their active ingredients, and some carry more uncertainty than others.
Throat Sprays Commonly Considered Safe
The throat spray you’ll see most often on OB/GYN “safe medication” lists is Chloraseptic, specifically the phenol-based version. Phenol works as a topical antiseptic and mild numbing agent. It’s applied in tiny amounts to the back of the throat and very little is absorbed into the bloodstream, which is why it’s generally considered low-risk. The spray is also sugar-free and available over the counter.
Benzocaine lozenges and sprays (found in some Chloraseptic and Cepacol products) are another option that may be considered throughout pregnancy. Human data has not shown a risk of birth defects with benzocaine use during the first few months of pregnancy or later. That said, the Cepacol brand specifically lists pregnancy as a precaution on its labeling, noting insufficient human data on developmental toxicity. The practical takeaway: benzocaine products are widely used, but the evidence base is thinner than for something like acetaminophen, so using them briefly and only when you genuinely need relief is a reasonable approach.
Menthol, which provides a cooling sensation and stimulates saliva production, is another common ingredient in throat lozenges and sprays. It’s found in many cough drops and is generally considered low-risk at the small doses used in throat products. Cepacol’s menthol-based sore throat spray is both sugar-free and alcohol-free, which can matter if you’re trying to avoid unnecessary additives.
What About Lidocaine-Based Sprays?
Lidocaine is a stronger numbing agent sometimes found in prescription or higher-strength throat products. The FDA previously classified it as Pregnancy Category B, meaning animal studies at doses over six times the human dose showed no evidence of fetal harm. However, there are no well-controlled studies in pregnant women. Lidocaine is not contraindicated during labor and delivery, which gives some reassurance about its safety profile, but lidocaine throat sprays are not typically the first choice for a simple sore throat during pregnancy when milder options are available.
Herbal Throat Sprays Carry More Uncertainty
It’s tempting to assume that “natural” means safer, but herbal throat sprays are one area where the opposite can be true. Herbal products are not required to prove they are safe or effective before being sold to the public, and many have not been well-studied for use during pregnancy.
Echinacea is a common ingredient in herbal throat sprays. Animal studies have suggested it might increase the chance of miscarriage, though it’s unclear how those doses compare to typical human use. One small human study found no increased miscarriage risk, and a larger study comparing over 350 echinacea-exposed pregnancies to more than 68,000 unexposed pregnancies found no increased chance of preterm delivery, low birth weight, or small-for-gestational-age babies. Still, some echinacea preparations have been found contaminated with heavy metals like lead, which can harm fetal development.
Propolis, slippery elm, and other botanical ingredients common in “natural” throat sprays have even less pregnancy-specific data. Another concern: many herbal sprays and tinctures use alcohol as a solvent, sometimes in significant amounts. Alcohol should be avoided during pregnancy entirely. If you do consider any herbal product, check the label carefully for alcohol content and talk to your provider first.
Simple Remedies That Carry No Risk
Before reaching for any medicated spray, a few drug-free options can meaningfully ease a sore throat. A warm saltwater gargle (about half a teaspoon of salt in a cup of warm water) reduces swelling and loosens mucus. You can do this several times a day with zero risk. Saline nasal spray, which is just salt and water, can also help if postnasal drip is contributing to throat irritation. The Mayo Clinic recommends it as a first-line approach for managing upper respiratory symptoms during pregnancy.
Honey (a tablespoon stirred into warm water or tea) coats the throat and has mild antimicrobial properties. Staying well-hydrated, using a humidifier, and sucking on ice chips are all effective and completely safe. These approaches won’t replace a medicated spray if you’re in real discomfort, but they’re worth trying first and can reduce how often you need to use any product.
Ingredients to Avoid
Some throat products contain ingredients that are more clearly problematic during pregnancy. Aspirin and ibuprofen (NSAIDs) sometimes appear in combination sore throat remedies and should be avoided, particularly in the second and third trimesters. Always check the active and inactive ingredient lists on any product. Multi-symptom cold products are especially tricky because they bundle several drugs together, and one or more of those drugs may not be appropriate for pregnancy.
If your sore throat is accompanied by fever, acetaminophen (Tylenol) remains the pain reliever and fever reducer of choice during pregnancy. ACOG reaffirms its safety when used at the lowest effective dose for the shortest necessary duration. This matters because untreated fever during pregnancy has been associated with increased risk of neural tube defects, oral clefts, and cardiac defects. Bringing a fever down is not optional.
When a Sore Throat Needs More Than a Spray
Most sore throats during pregnancy are caused by the same viruses that affect everyone else and resolve within a few days. But certain signs suggest something more serious is going on. A fever of 100.4°F or higher warrants prompt medical attention, especially during pregnancy. A sore throat lasting more than a few days, difficulty swallowing or breathing, swollen lymph nodes, or white patches on the tonsils could point to strep throat or another bacterial infection that requires antibiotics. Strep throat left untreated can lead to complications that pose real risks during pregnancy, so don’t wait it out if those symptoms appear.
