Hi,
Theraflu is a combination of medicines for flu and cold symptoms. This medicine is to be used according to the directions of your doctor. Though, the symptoms of
depression and suicidal ideations have not been described as the side effects of this drug, still,
dizziness,
drowsiness, feeling restless or excited as well as sleep disturbances have been described some of the common symptoms.
It is better, that you stopped using this drug, as this drug should not be used for a prolonged time and particularly, never use this drug for sleep purpose. However, the symptoms in your case seem more to be unrelated to this drug. These may be due to some psychological problem. Hence, you are advised to see a
psychiatrist in this regards and treatment done accordingly.
Take care. Hope I have answered your question. Let me know if I can assist you further.
Regards,
Dr. Satnarain Bansal, General & Family Physician
