You should not take Xithromax while breastfeeding. Xithromax belongs to the antihistamine class of drugs, which can be absorbed into the blood circulation after oral administration and enter the baby’s body through breast milk, affecting the baby’s health. Xithromax, also known as loratadine, is mainly used to treat allergic diseases, such as allergic urticaria and allergic rhinitis. A common adverse reaction after taking it is affecting the normal function of the cardiovascular system, possibly causing tachycardia and arrhythmia, so it is recommended to be taken with caution during breastfeeding. It is better not to take cimetidine, aminophylline and other drugs at the same time of taking Xyosmin to avoid affecting the metabolism of the drug and inducing or aggravating adverse drug reactions. Breastfeeding is a special physiological period for women, so it is recommended not to take drugs at will. If you must take them, take safe drugs under the guidance of a doctor, and pay attention to a reasonable diet and do not consume foods that can easily cause allergies.
