The main ingredients of some common lozenges are white sugar, glucose syrup, fatty sea, mulberry leaf, mint, tea and other ingredients. In fact, many of the ingredients are herbal medicines. The instructions of these lozenges also say that they should be used with caution by pregnant women or under the guidance of a doctor, which means that they are generally not recommended for pregnant women. Generally, if a pregnant woman has throat discomfort and there is no clinical pus or congestion, it is recommended that she should drink more warm water, gargle with light salt water, eat more sorbet or drink some sorbet stewed with rock sugar to relieve throat discomfort. If a pregnant woman’s throat is congested or pus filled, it is not useful to take throat lozenges in this case. It is necessary to consult an otolaryngologist and an obstetrician-gynecologist to decide on anti-inflammatory treatment with antibiotics that have minimal side effects on pregnant women.
