Hi, Thanks for the query to H.C.M.
Some 4 wk ago you started
chantix and 3 wk ago drug for UTI.
Your's question is that you are feeling
nausea, exhaustion,
fatigue,headache and of course uneasiness and
restlessness.
I would like to that cumulative effect in one thing in which when two drugs are taken simultaneously their side effects increases ( even more than combined).
In your's case nausea, fatigue, etc were the side effects of chantix and you also took drug for U T I.
This is the tendency of antibiotics to produces some nausea and heart burn ( hyper acidity).
So these two plays a havoc.
Now consult a doctor and take some medicines which will cure these above mentioned symptoms.
I think your's U T I has been cured. So it will be easy for you to have one drug.
Good luck.
Dr. HET
