I was prescribed amoxicillin & phenylephrine HCl for sinusitis. Next day, I found out I'm pregnant. Should I continue/finish the prescription?

I was prescribed amoxicillin & phenylephrine HCl for sinusitis. Next day, I found out I'm pregnant. Should I continue/finish the prescription?

Finish amox: Finish the Amoxicillin but stop the phenylephrine. Phenylephrine casues blood vesles to constrict. This will open you nose up but will also decrease placental blood flow.

Be careful: Pseudoephedrine and phenylephrine are stimulants and Excedrin contains caffeine, all of which if taken together could cause nervousness jitteriness and possibly palpitations. Do NOT overmedicate. Nyquil can be sedating in certain individuals.

My dr recommended cough syrup with guaifenesin to better CM for helping conceive. Will it still work with phenylephrine HCL 10mg in it? No dm though.

What?: I might be misunderstanding your question, but are you under the assumption that guaifenesin will help you to conceive a child? Cough syrup, of any kind, will not enhance you chances of becoming pregnant...It will however help your cough... If I'm misunderstanding please repost your question.
