During pregnancy, it is not recommended to drink cough syrup if you have a cough, because many cough syrups have sedative ingredients that can relieve coughs caused by spasms in the bronchi. These ingredients have a certain effect on the development of the fetal nervous system, so it is best not to drink cough syrup if you have a cough during pregnancy. At this time, if the cough is not very serious, you can take a dietary treatment to help stop the cough, such as cooking garlic and rock sugar water. If you do not have elevated blood sugar, you can take 30 grams of garlic and 10 grams of rock sugar, add two large bowls of water, then put them in a pot and boil them for about 20 minutes, boil a small bowl of water left in the two bowls and drink it while it is still hot. In addition, most coughs are caused by infections, so you should also use anti-inflammatory drugs, such as Pudilan Anti-inflammatory Oral Liquid and Banlangen Granules for antiviral treatment. If the infection is bacterial and you are not allergic to penicillin, you can take amoxicillin orally for anti-inflammatory purposes.
