Generally, you should not drink antiviral oral solution during breastfeeding to prevent the drug from adversely affecting the growth and development of your baby. Serious illnesses should be suspended after breastfeeding to use the drug. Antiviral Oral Liquid can be used to treat diseases such as wind-fever and influenza. Usually, anti-viral oral solution should not be drunk during breastfeeding, mainly because the drug can easily enter the baby’s body through breast milk, which to a certain extent may adversely affect its growth and development. However, if a breastfeeding woman’s condition is serious, she can take oral antiviral solution under the guidance of a doctor, with the precondition that she stops breastfeeding. Breastfeeding can be resumed after the body has fully recovered and the drug has been metabolized. In addition to this, Antiviral Oral Liquid is contraindicated in people who are allergic to the product, pregnant women and so on. However, there is no clear information about the adverse effects of this drug. In conclusion, when a breastfeeding woman is not feeling well, she needs to go to the hospital in time and use the drug in strict compliance with the doctor’s instructions.
