Pregnancy should not be considered a contraindication to oseltamivir or zanamivir use. Pregnant women might be at higher risk for severe complications from swine influenza, and the benefits of treatment or chemoprophylaxis with zanamivir or oseltamivir likely outweigh the theoretical risks of antiviral use.
566175 tn?1278430472 Treatment and chemoprophylaxis The currently circulating swine influenza A (H1N1) virus is sensitive to the neuraminidase inhibitor antiviral medications zanamivir and oseltamivir, but is resistant to the adamantane antiviral medications, amantadine and rimantadine. Pregnant women who meet current case-definitions for confirmed, probable or suspected swine influenza A (H1N1) infection should receive empiric antiviral treatment.
Avatar n tn hi my friend had unprotected vaginal intercourse with a CSW , after three months he did Hiv-1,2 antibody combo test i came back with negative , but one week before he had influenza b positive , for this one he took oseltamivir tablet 75 mg tablet 9 nos for 5 days , these tablets can affect the test result? Kindly confirm he needs to check again three months antibody test is conclusive.
11062655 tn?1414987783 htm Hepatotoxicity Despite widespread use, there is little evidence that oseltamivir when given orally causes liver injury, either in the form of serum enzyme elevations or clinically apparent liver disease. A proportion of patients with acute influenza A may have minor serum enzyme elevations during the acute illness, but these appear to be independent of therapy and are not exacerbated by osteltamivir.
9648 tn?1290091207 re part of a study, you might be able to settle any argument with your dr by getting her to run a plasma HPLC assay - ultimately that's the factor that correlates with outcome: "Prediction of sustained virological response by ribavirin plasma concentration at week 4 of therapy in hepatitis C virus genotype 1 patients." http://www.ncbi.nlm.nih.

Avatar f tn s sudden appearance might have been a side effect of TAMIFLU which is now known to rich (oseltamivir substance) the blood-brain barrier and cause irreversible dammages to brain. As a conclusion, TAMIFLU appeared to be responsable of a "medecinal intoxication" causing the narcolepsy-cataplexy I suddenly suffer since then. Several Years after, we hear about narcolepsy cases caused by the massive H1N1 vaccinations...
372366 tn?1284403873 Copyman, I think we have a rhyme for teleprivir now). Ribavirin is not one of those listed. But being a suspicicious person, I have a theory of why riba is not a suggest 'stockpiled' anti-viral. If governments and business were to create significant stockpiles of ribavirin they could be accused of accumulating weapons of mass destruction. And we all know what that could cause.

Avatar m tn if any family members are aged, frail, or have other underlying illnesses, s/he definitely should see a doctor. They may be candidates for oseltamivir (Tamiflu), which speeds recovery and helps prevent complications. Also, even healthy or strong individuals benefit it started early -- anyone who is just starting to become ill (within 2-3 days) should see the doc.
Avatar n tn 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).
Avatar m tn 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.
Avatar f tn 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.
Avatar f tn 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.
Avatar m tn 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.
Avatar m tn hi doc, As you know, I will be looking to do my antibodies test on the 42 day mark. I am currently now on a course of Tamiflu aka Oseltamivir. My question would it cause my test result to be invalid. Thanks this would be my last question.
26471 tn?1211936521 s different now, but two years ago when treating I found it impossible to test for serum riba levels (HPLC technology) in this country. I was about to hop a plane to Sweden to test when I hit the riba wall (ended up in the ER) and decided I probably was at my maximum dose :) HPLC testing would have been a bit more elegant!
Avatar n tn 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.
144210 tn?1273088782 re comparing a 12-year old study that would be easy to implement (tapering) with a recent finding that would be very difficult to implement (if not impossible) in this country because HPLC testing for serum ribavirin is not available in clinical settings. Also, my guess is that Shiffman is quite flexible on riba dosing (other than weight) if he's in sync with some his collegues that I've consulted with.
Avatar f tn Hi to all, Hope you're all having a peaceful, not crazy holiday season! I have a question. I've had lingering bronchitis since 11/17. Started Harvoni :-) 12/1 4 wk labs on Monday. I'm feeling really good now w/ Harvoni end week 4. Unfortunately :(, I have been at veterinarian hospital with a very sick cat many days this week. Unfortunately, many staff there, including doc in room with me have been hit with H3 flu.
Avatar f tn Thanks for the answers. Has anyone taken theraflu while on treatment? My boyfriend has a cold and I did my shot last night, so I wont know if it is the shot or the cold?!!??
168348 tn?1379357075 They make you feel better faster and may prevent serious flu problems. The antiviral drug Tamiflu (also known as oseltamivir) is recommended for treating 2009 H1N1 virus infection and may be prescribed for persons with asthma. Flu treatments work best if they start within two days of when you get flu-like illness. * Persons with flu infections might also get bacterial infections. These persons will also need to take antibiotics to fight the bacterial infection.
158241 tn?1237719523 Eleven patients (35%) achieved SVR, whereas 20 (65%) were non-responders. The median ribavirin plasma concentration at W4 (1.90 mg/l) varied from 1.62 mg/l in patients with subsequent non-response to 2.28 mg/l in sustained responders (P=0.007). Receiver operating characteristic curve analysis indicated that the 2.01 mg/l threshold gave the best sensitivity and specificity (73% and 80%, respectively, area under the curve =0.80; P=0.007).
Avatar m tn 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.
Avatar m tn 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.
