Thank you for your question.
You did not mention how old the baby is. Most pediatricians do not encourage the use of over the counter remedies in babies under the age of six months. The reason is that they frequently don't work and are not administered in the right dose.
If she is under 12 months old, you need to check a rectal temperature so that is accurate. Many of the products on the market are not accurate including the tape and the thermometer that does in the ear. If the baby is 6 weeks or less and has a temperature of 100.4 or more, you need to have the baby seen.
If she has a rash
, irritability, she also needs to be evaluated promptly.
In general when babies have colds and throat issues, it is much better to have a humidifier in the room than to give any drug.
I hope this helps,
