I think blue pen syrup is the best.

At first, I thought this was a suppository, but it turns out to be an infant fever reducer.

If it is infants and young children, of course, it would be that, but if it is young children, I think it might be blue pen syrup.

Of course, I don't have recent experience, so there are some unfamiliar medications as well.

When I was frequently using infant fever reducers, there was nothing better than Brufen syrup.

The children ate well without any resistance, and I remember that the medication took effect quite quickly.

Isn't there a reason why old medicines are still around?
