I advise that all drug be avoided in pregnancy, but these medications are apparently safe and can be used if needed. Use a specific medicine for a specific problem, for example. Nyquil (aside from it's alcohol content) is a shot gun therapy that treats everything. This is taking more than may be needed for the problem you are facing. These medications are also safe during breast feeding.
