That is the basis of vireads nephrotoxicity inclination, sinde Viread , which is tenofovir disoproxil fumarate ( TDF), falls apart rapidly in plasma, producing pure tenofovir, that goes to the kidney and is picked up there.
Nevertheless, while still intact, enough TDF enters the liver cells, where is it finally converted in several steps to tenofovir diphosphate, which is the actual substance that inhibits the viral polymerase.
He advised me since hcc and genotype c with bc / pc mutation I should take ectecavir right away. He wanted to give me Tenofovir but since my kidney function is not that good with 1.28 serum creatinine he felt ectecavir was best choice for me. I wanted to try telebvuidine but he did not want to prescribe. I told him I could benefit maybe with a combo telb / tenf as seen in some studies.
Doctor asked to take Lamuvir, absolutely do not take that drug, the only firstline drugs are tenofovir, entecavir, interferon.
Nephrotoxicity has been reported in 3% of patients with compensated liver disease after 4-5 years of continued adefovir therapy.
Entecavir: a similar safety profile as lamivudine in clinical trials. Studies in rodents exposed to doses 3 to 40 times that in humans found an increased incidence of lung adenomas, brain gliomas and HCCs.
L-deoxythymidine (Telbivudine/LdT, Tyzeka): well tolerated when used as monotherapy and has a safety profile comparable to lamivudine.
(20) The T69S insertion mutations, associated with resistance to multiple nucleoside analogues, are associated with resistance to tenofovir as well. Tenofovir resistance conferred by the T69S mutation or by multiple thymidine analogue resistance mutations appears to be multiplied if the M184V mutation is replaced by wild-type.(21) The K65R mutation, which may be selected by prior nucleoside analogue therapy, is associated with a modest decrease in sensitivity to tenofovir.
Association of Higher Plasma Vitamin D Binding Protein and Lower Free Calcitriol Levels with Tenofovir Disoproxil Fumarate Use and Plasma and Intracellular Tenofovir Pharmacokinetics: Cause of a Functional Vitamin D Deficiency?
"The finding of a 26% increase in vitamin D binding protein and a 42% decrease in free 1,25-OH(2)D between the lowest and highest quintiles of plasma tenofovir has not been previously reported.
The following is a paper from doctors in Francel. It said you can breastfeed whilst your are on Tenofovir because "Tenofovir is not absorbed in the breast milk". However, I have googled and cannot find any reference to this claim. All the best to you and your baby.

Hi stef good day. U still there?? I have some question stef about taking tenofovir because i dont know what to do. Im start taking tenofovir september 2020 and i notice that february my urine have bubles until now my urine still foamy or bubles but in evening is normal.
Tenofovir can cause proteina stef??
tenofovir, no resistance
entecavir, 1,5% resistance but cannot be used on those using lamivudine because in this case resistance can go higher than 50%
interferon
if i had a doctor prescribing me such rubbish useless toxic.....i d destroy his life....
I am on tenofovir from March 2012 when i am pregnant at week 32. At that time i had hbs and hbe both positive.
Hi All,
Is there a way I can have a prescription from a doctor when buying tenofovir online? Here in the Philippines, the drug is not yet available and the doctors are not prescribing it since it is not available. I'm planning to take tenofovir but having trouble in getting prescription, so i cannot order online.
Please advise.
I took tenofovir from the 3rd trimester and my baby is fine till now but i stopped using it when she 2 months and start again 2 days ago since.
hbv has no symptoms, you may even be dying and feel nothing
tenofovir improves kideys function especially tenofovir+telbivudine in those with kidneys function.
