Druginformer Identified Side Effects: Hunger, Hunger pain, Dizziness or vertigo

Effectiveness Rating:     Overall Rating:

I love how well my brain works on this plus Effexor XR. The hunger and dizziness worry me. I'm on Weight Watchers to help me lose weight and I am allowed 30 points a day. I eat all 30 points but sometimes it's like I haven't eaten anything. I can get so hungry I am nauseous. My doctors all say this is unusual because usually this is an appetite suppresent. I think it has sped up my metabolism. The last two days, I have added a peanut butter granola bar because, yesterday, despite eating half a serving of shepherd's pie and half a piece of cornbread, I felt empty like I haven't eaten in days. I decided to ignore the points and listen to my body. When I started methylphenidate in late August, I weighed 205 lbs (I am 41 years old and am 5'2. Just diagnosed with ADD and Aspergers in August). I now weigh 165. The medicine has helped me organize things and develop a sleep pattern, two things I have never been able to do. I do worry about the hunger and dizziness, though.

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.
