A cough is how your body clears irritants from the throat and airways. Most coughs come from colds, flu, or allergies and get better in a few days. Some last longer or point to other problems like asthma, acid reflux, or side effects from medicines (ACE inhibitors). Below are clear, useful steps to feel better fast and know when to see a doctor.
Start with simple things that work: rest, fluids, and humidity. Hot drinks soothe the throat and loosen mucus; try warm water with lemon or a decaffeinated tea. Use a humidifier or sit in a steamy bathroom for 10–15 minutes to ease tight airways. For adults and children over 1 year, a spoon of honey can reduce night cough and help sleep. Don’t give honey to infants under 12 months.
Over-the-counter options: dextromethorphan helps dry, annoying coughs while guaifenesin thins mucus when you have a wet cough. Menthol rubs or cough drops relieve throat irritation for short periods. Read labels and follow dosing—kids need smaller doses and some products aren’t safe for young children.
Avoid smoking and smoky places — cigarette smoke makes coughs worse and slows recovery. Keep home air clean and wash hands often to prevent spread if your cough is from a virus.
See a doctor if your cough lasts more than three weeks, brings up blood, causes shortness of breath, or is paired with a high fever (above 100.4°F / 38°C). Also get checked if you have wheezing, unexplained weight loss, or night sweats. For kids, seek care sooner: difficulty breathing, poor feeding, high fever, or if the cough sounds like whooping or barking.
Antibiotics only help bacterial infections. Most coughs are viral, so antibiotics won’t help and can cause side effects. Your provider will test and decide if antibiotics or other treatments are needed — for example, inhalers for asthma, proton-pump inhibitors for reflux-related cough, or stopping an ACE inhibitor if that’s the cause.
Buying cough medicines online? Use verified pharmacies that require prescriptions for prescription drugs, show a physical address, and use secure payments. Avoid sites with unreal discounts or no contact info. Keep a list of current medicines to avoid dangerous interactions, and ask a pharmacist if you’re unsure about combining cough products with other drugs.
Keep a short symptom diary: when the cough started, triggers, times it’s worse, and any meds tried. That helps your clinician make faster, smarter decisions. Small steps at home often help, but don’t wait if breathing gets hard or symptoms keep getting worse.
Coughing is often seen solely as a physical issue, but there's more to it than just a tickle in the throat. Emerging research shows a connection between mental health and chronic coughs, where stress and anxiety can exacerbate coughing symptoms. Understanding this link can lead to more effective management and relief. By addressing both physical and mental factors, you can tackle those persistent coughs more holistically. Discover practical tips and insights in managing your cough with mental well-being in mind.

It turns out, this antibiotic has shown promising results in treating both acute and chronic sinusitis. The study suggests that Minocycline may reduce inflammation and bacterial growth in the sinuses, providing relief for those suffering from sinus infections. However, it's important to consult with your doctor before using this medication, as it may not be suitable for everyone. So, if you're struggling with a sinus infection, Minocycline might be worth looking into as a potential treatment option.
