Druginformer Identified Side Effects: Paranoia, Depression, Aggression, Depressive symptom

Effectiveness Rating:     Overall Rating:

Posted By Antony on April 21, 2018 @ 6:41 pm

It took me over a year before I correlated this drug to subtle feelings of paranoia. It would happen in waves, and unpredictable. Examples, feeling that people at work were against me, management wanted me gone, friends were scheming against me. I have NEVER had these feelings ever before. As mentioned it took over a year to perceive what I've mentioned. Very subtle, but when a wave would hit its peak it was substantial, but I never thought this drug was the cause. Now I do. I am going back to the doctor to find out the best way to withdraw from this drug. I found a medical document mentioning that in fact that this product increases overall blood serum levels of testosterone by ~10%, and I have no doubts about this. My sex drive, in waves, has been through the roof, and mood has been not like I usually am, but, again, subtle and in waves. Stopping consumption of this product as soon as I can. I am now at approx. 1.8months on it. Unfortunate, but has to be done.

Additional Drug Information


* Warning: The facts and figures contained in these reports are accurate to the best of our capability; however, our metrics are only meant to augment your medical knowledge, and should never be used as the sole basis for selecting a new medication. As with any medical decision, be sure to work with your doctor to ensure the best choices are made for your condition.

* About FAERS: The FDA Adverse Event Reporting System (FAERS) is used by FDA for activities such as looking for new safety concerns that might be related to a marketed product, evaluating a manufacturer's compliance to reporting regulations and responding to outside requests for information. Reporting of adverse events is a voluntary process, and not every report is sent to FDA and entered into FAERS. The FAERS database may contain duplicate reports, the report quality is variable, and many factors may influence reporting (e.g., media attention, length of time a drug is marketed, market share). For these reasons, FAERS case reports cannot be used to calculate incidence or estimates of risk for a particular product or compare risks between products.
