What Causes Dizziness, Itchy Skin And Depression After Having Fentanyl Injections?
the fentanyl doesn't stay in the system much
Detailed Answer:
cannot say in her particular case without directly seeing her and, several medications cause confusion and sedation (abilify... a powerful anti-psychotic. trazone an anti-depressant used also for sedation, zonisamide--like all anti-epileptic drugs damps down the brain and drugs can also have side effects). Fentanyl injected into the back should be a small amount and when it gets out of the back the total amount shouldn't be high enough to do much. Furthermore, the question implies the mental dullness and other symptoms are chronic and the injections are more episodic. Furthermore, the number of drugs all with indications other than pain imply a lot of other condtions that can and will also interact with the medications and the underlying conditions can also cause mental issues. While fentanyl as a patch often causes confusion, the relation between the drug and any particular side effect is not so easy to establish when the amount of the fentanyl getting to the brain from an injection is likely to be tiny and the other drugs and other issues are quite large.
