To help you best, treatment depends on the type of cough. For a dry, tickly cough, an over-the-counter cough suppressant containing dextromethorphan can provide relief. For a wet cough with mucus, an expectorant like guaifenesin helps loosen and clear the phlegm. Additionally, staying well-hydrated with warm fluids like tea with honey, and using steam inhalation can greatly soothe your throat. Please avoid cold drinks and rest well. If your cough persists for more than two weeks, or is accompanied by high fever, shortness of breath, or chest pain, please consult a doctor for a physical examination.

At four months, you are safely in your second trimester. For a mild cough, it is best to start with drug-free remedies like staying well-hydrated, using a cool-mist humidifier, and having a spoonful of honey to soothe your throat. If you need over-the-counter medication, generic dextromethorphan (to suppress a dry cough) and guaifenesin (to help clear mucus) are generally considered safe to use during this stage of pregnancy. Please avoid multi-symptom formulas, alcohol-containing syrups, or decongestants. Always consult your OB/GYN or midwife before starting any new medication to ensure it is safe for your specific pregnancy.
