Arre, simple haldi doodh (turmeric milk) piyo and salt water gargle karo. Drastic medicines lene ki koi zaroorat nahi hai jab tak fever na ho. Take some rest.
Please check with your gynac once before trying any herbal remedies or taking any pills. Pregnancy makes our bodies very sensitive, so it is better to stay safe and get a doctor's opinion.
Whenever I got a sore throat during my pregnancy, I just stuck to warm saline gargles 3-4 times a day. Steam inhalation also worked wonders for me without taking any tablets.
While warm liquids can give temporary relief, it is always best to let your doctor know before taking any OTC lozenges or cough syrups. Self-medication can be risky during pregnancy, so a quick call to your gynac is ideal.
My doctor advised me that most sore throats are viral and heal on their own with rest and hydration. But if you have a fever or difficulty swallowing, you might need a safe antibiotic prescribed by your gynac.
