Can I take Zoloft 100 mg if I have panic attacks, shortness of breath, palpitations after taking the drug?

I take Zoloft for 8 months. 100mg often happens that after taking a pill, the condition worsens, palpitations, lack of oxygen, it seems as if I am suffocating, often a panic attack. My neurologist knows about everything, but prescribes to take it further. The question is, is this condition normal and if so, is it possible to remove these symptoms with something? Valerian infusion, I drink Corvalol, the effect is imperceptible
