invega
Finally, since about year he began giving him INVEGA (paliperidone) injection 50 mg which he is fine with it.
The problem is that he has become sperm non-existent as he told me.
Will it disappear in case he stop taking the injection after a long period of use???? I am very confused, particularly as he wants to get married and be a father.
For the past couple years I have been on paliperidone which is generic for invega which I know can cause extreme weight gain. Couple that with my increasingly poor eating habits, I definitely ballooned in weight. For about the past two months I have gone on a heavy calorie restriction that I know is deemed to be unsafe and unhealthy. I want to say now that with respect, I would prefer you focus on my question at hand and not about telling me to eat more food than I currently do. Thanks.
Well will wonders never cease? Are we surprised about the information? I guess they had to spend money on something after they couldn't buy donuts for doctors offices anymore.

was 5 points high, good cholest was 5 points low. Bun/creatine ratio was a little low, but the numbers themselves were avg. HPLC was 5.7 (5.6% was the top range for normal). Bacteria was classified as rare. Since then, I've had a few good days in terms of bowel movements, but experience discomfort (not pain really) below the ribs (upper middle) on both sides (sometimes more on the left side), lower back, and mid-back (though i think the mid-back is from lifting my daughter).
This paper btw seems very consistent with other similar studies, including those that show serum riba levels (via HPLC testing) help deterimine both RVR and SVR. Unfortunately HPLC testing for serum riba levels is not available except in trial situations, but if it were, then one could reasonably pre-dose and keep increasing the riba dose until a set serum riba level was met.
These 35 patients had urinary free cortisol determined by both HPLC and competitive binding methods. The efficacy of the HPLC assay using cortisol alone was equivalent to that of the competitive binding assay; 22 of 29 (76%) patients had increased cortisol. Cortisone also aided in the diagnosis; 25 of 29 (86%) had increased cortisone. Twenty-seven of the 29 (93%) patients had either both cortisone and cortisol (n = 19) or at least 1 of the 2 (n = 8) increased.
Hi Swish,
Welcome to MedHelp's Pain Management Forum. I'm glad you found us and posted your question here.
As usual our Remar has offered some good information. UDT (urinary Drug Test) is a chemical science - either well or poorly understood by PMP. Chemistry was never my strong suit - and that's what UDTs are all about.
It depends on the type of UDT your PMP utilized.
Lindahl mesured riba absorption through HPLC (high performance liquid chromatography) testing which is not available in this country, unless perhaps in some research labs. Unfortuantely, very little work here in this area which could potentially have salvaged many, many SVRs, but resources (money and white coats) are elsewhere, mostly with the PI's. I expect we will see some pre-dosing studies soon and maybe some enlightened clinicians will start demanding HPLC testing for their patients.
You have a high urine - (and the doctor used a test that is less sensitive, there is a more sensitive test that has a lower range using a method called HPLC). The high calcium shows that you may have a parathyroid issue - and that should be addressed as well - in fact, if you have that, with a pituitary and adrenal tumor, the doc should be evaluating you for MEN - multiple endocrine neoplasia. Just my thoughts out there.
BTW , if you are checking out Vit B12 you might as well take a look at your Vit A.
VITAMIN A DEFICIENCY NEGATIVELY AFFECTS THE RESPONSE TO ANTIVIRAL TREATMENT IN PATIENTS WITH CHRONIC HEPATITIS C
Background and aim:
Vitamin A deficiency has been associated with enhanced susceptibility to virtually all types of infections, through a modulating action on innate and adaptive immunity.
Now there are a few papers that have actually measured, in a reliable well documented HPLC fashion, the achieved RSV concentration in the blood of human subjects after exposure to 250 and 500mg of 99% transResveratrol.
The concentration of total phenols may also be indicated on the labels of echinacea products. The total phenolic content (determined by HPLC) should be at least 1% for quality whole herb or root products and proportionally higher for extracts and tinctures depending on their concentration.
Almost all the clinical studies showing benefit have been conducted with products extracted from the aerial (i.e., stems, leaves, flowers) portions of E.
Urine was collected for 24 h after consumption of each treatment for analysis of CGA and metabolites by HPLC/LC-MS. The amount of CGA and metabolites recovered after consumption of combined coffee-milk (40% ± 27%) was consistently lower in all subjects compared to that of coffee alone (68% ± 20%). Concluding, the simultaneous consumption of milk and coffee may impair the bioavailability of coffee CGA in humans.
Patients and methods Serum ribavirin concentration of 183 chronic hepatitis C patients (genotype 1) treated with pegylated interferon-α2b plus ribavirin for 48 weeks was prospectively measured by HPLC at weeks 4, 12, 24, 36 and 48. Patients with undetectable serum hepatitis C virus (HCV) RNA 24 weeks after the end of treatment were designated as having sustained virological response (SVR).
A high-performance liquid chromatography (HPLC) method was used to analyse serum drug concentrations. Caffeine caused a highly significant (p < 0.01) increase in AUC and AUMC, a significant (p < 0.05) increase in Cmax, and a significant (p < 0.05) decrease in clearance (C1/F) of acetaminophen. We conclude that caffeine taken in doses commonly available commercially or in a cup of coffee can significantly potentiate the therapeutic potential of acetaminophen in man.
