Sinequan belongs to the drug group called tricyclic antidepressant. The mechanism it follows is not fully understood by the modern medical science; the most general opinion is that it increases the activity of certain mood-elevating chemicals in the brain. It is mostly used for depression and anxiety-inclusive disorders treatment.
If you have been known to be allergic to other tricyclic antidepressants in the past, do not even begin taking Sinequan. Also, you must not use this medicine if you have glaucoma, asymptomatic prostatic hypertrophy, or other prostate conditions. It is strictly forbidden to take Sinequan if you are using such medicines as clonidine, astemizole, terfenadine, ibulitide, furazolidone, phenelzine and other similar drugs or have used them within the past two weeks. If any of the aforementioned factors apply to you, warn your healthcare provider in advance.
The common side effects of Sinequan include drowsines, dizziness and occasional spells of blurred vision. You should not drive or perform any tasks at all that require you to be fully alert and aware of the surroundings until you know exactly how strong your reaction to Sinequan is. If you feel lighthearted or faint, lie down immediately. The dizziness may increase when your sit or stand up, so perform these actions slowly and carefully. Note that Sinequan's side effects are increased by alcohol, excessive physical activity, heat, or high fever.
