I've been taking Effectin for almost 3 weeks, but I still feel stinging in my chest, nervousness, shortness of breath and dizziness – will the drug help me and when can I expect improvement?

To @Ania:

Reducing the dose of Efectin (venlafaxine) to 75 mg is possible, but should be done under medical supervision. Dosage decisions should be made based on clinical judgment by a specialist.

The symptoms you describe, such as nervousness, dizziness, shortness of breath, tiredness and excessive sweating, may be related to your medical condition. It does not necessarily have to be the result of the drug used. It is important to discuss these symptoms with your psychiatrist at your next appointment to tailor your treatment to your needs.

If you are not able to make a face-to-face visit, I attach a link to the online teleconsultation:

And what if I feel worse in the sense of all the time I'm nervous, I still have dizziness, shortness of breath, tiredness and I sweat terribly. Can I reduce the dose to 75 mg? 12 I have an appointment with a psychiatrist.

To @Ania:

Such symptoms are usually transient and disappear after 7-21 days. Usually, these side effects appear within the first days of treatment, but in some patients they may not be observed until a few days after the start/dose increase.

How long does it take for these undesirable symptoms to disappear?
