Example provided

Example 1: Larger text - uses 2 labels
Swallow whole ONE tablet in the morning *May cause drowsiness and increase effects of alcohol. If affected do not drive a motor vehicle or operate machinery.
157 characters

Example 2: Compressed text - uses 1 label
Swallow whole ONE tablet at night *May cause drowsiness and increase effects of alcohol. If affected do not drive a motor vehicle or operate machinery.
151 characters

Although example 1 does contain a higher character count, it does appear that if it had used smaller text it would have been able to fit into 1 label.

Improved logic is required to make better use of small text and avoid need for additional label.
