In some people, tenofovir can increase creatinine and transaminases. These are enzymes related to the kidneys and liver. High levels can indicate damage to these organs.
Tenofovir can reduce bone mineral density (see fact sheet 557). Calcium or vitamin D supplements may be helpful. This is especially true for people with osteopenia or osteoporosis.
Levels of lactic acid in the blood (lactic acidosis, see Fact Sheet 556) increase in some people taking nucleoside analog drugs.
An international study found the antiviral combination of tenofovir and emtricitabine (Truvada) was most effective in treating younger adult hepatitis B patients with high viral load and normal ALT levels.
Doctors historically have not treated this group because there appeared to be no sign of liver damage. However, doctors now know that high viral loads may increase patients’ risk of liver damage and cancer as they age, despite their normal ALT levels.
The most common treatment in the US, Canada and the UK is Truvada. This is what is known as a "fixed-dose combination tablet" combining emtricitabine and tenofovir from the NRTI class, and raltegravir, from the integrase inhibitor class. There ARE alternative drugs available and possibly in Thailand they use lamivudine in place of raltegravir. I am definitely NOT a chemist, so I can't tell you for sure if the combination you're taking is appropriate.
What are my chances of getting infected. Another question was administered a PEP drug emtricitabine and tenofovir, can it prevent me from contracting HiV.
You are correct that Truvada is a combination of tenofovir and emtricitabine, and is generally prescribed for patients with HIV. Being a HBV forum, most of us know very little about Truvada except that it is prescribed off-label for HBV by some doctors, and that it is recommended for HBV patients who develop resistance to Tenofovir.
Given you are resistant to LAM, staying on Truvada is obviously better. But going mono on Tenofovir should be ok given you current UND. Tenofovir has a excellent resistance profile especially in UND situations. Even if you are resistance to LAM, can you access Entecavir as a possible combo with Tenofovir?
Good afternoon. There is a double-acting drugs - lamivudine, emtricitabine, tenofovir. This is known. Are there any similar action in the protease inhibitor, such as Kaletra (lopinavir) for example?
Have you ever thought about that?
I read - sometimes laugh. Simvastatin, vitamin D, which the Chinese poeben, mythical new drugs, masturbation with measurements of the level of HBsAg, and other nonsense....
This is a potential concern because the drugs in Truvada – tenofovir and emtricitabine – are active against HBV as well as HIV.
HIV and HBV are spread through some common transmission routes, including sexual transmission, vertical transmission (mother to child) and via multi-person use of injection equipment.
truvada is just tenofovir+ftc, it is sueless on hbv unless non response to tenofovir, which is extremely rare
it adds toxicity and higher price because truvada patent is not expiring in 2014, no difference on hbsag.
instead of truvada it is best only for those non responding to combo tenofovir+lamivudine.
the explanation of why tenofovir is so potent on hbv and makes no resistance was explained by the intracellular levels reached by this drug, it is so bad no study ever showed how all other nucs are extremely poor at this and when i found this comparison i was very very surprised
all ohter drugs are so weak as intracellular levels, just look at lam vs tdf.we dont have etv here but it is probably very poor too.
I started a course of PEP that included Tenvor-EM (Indian version Emtricitabine/Tenofovir DF) and Kaluvia (generic of lopinavir/retonavir) for 25 days and interrupted it for two reasons:
1-My partner tested Negative(Antigen/ Antibody) on 22 days post exposure
2-Thinking that i might be developing facial Lipodystrophy (slight facial fat loss under cheek bones). I cant tell if my face was like this before the treatment or it is just an illusion.
tenvir is generic version of tenofovir
tenvir tm is generic version of tenofovir+emtricitabine (truvada) which even more potent than tenofovir alone
entecavir is less potent of both tdf or truvada, i am also on entecavir which is about 1000usd per month changing currency from euro, i have it free in my country but it is absurd to allow such costs for a stupid tablet

Objectives
To report a successful treatment of a patient with a chronic severe hepatitis Delta using combination therapy with Pegylated interferon (PegIFN), Tenofovir disoproxil fumarate (TDF) and Emtricitabine (FTC).
Study Design
The patient, a 47 years -old male patient, originating from Dagestan (East Asia), suffered of chronic hepatitis Delta infection. The patient was HBsAg, HBeAg, and anti-Delta Ab (IgG) positive. Serum HBV-DNA level was elevated (more than 9logUI/mL).
This new drug was approved by the FDA in April and is now avaliable in the USA.
Truvada was used for hbv patients with less than optimal response to viread and is considered somewhat more potent and even less resistance prone than viread.
Now Gilead has exchanged the 300mg TDF in Truvada with 25mg of TAF, making it well suited for hbv patients with kidney concerns.
To evaluate amino acid changes within HBV pol/RT after up to 240 weeks of tenofovir disoproxil fumarate (TDF) treatment and determine their potential association with resistance to TDF. No TDF resistance has been detected through 192 weeks of TDF treatment. Methods: Patients in Studies GS-US-174-0102 (HBeAg-) and GS-US-174-0103 (HBeAg+) were randomized 2:1 to receive TDF or adefovir dipivoxil (ADV) for 48 weeks followed by open-label TDF.
Thoughts? My thought it that will this drug is good, they need to speed up the cure instead of focusing on trying to "pimp" this drug.

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.
Within 36 hours i went to a commercial walk in clinic and was given a 1g intramuscular injection of ceftriaxone and a 28 perscription of PEP 1 pill (tenofovir, emtricitabine, dolutegravier). After reading more and more it seems like the PEP might be overkill in my situation, and the clinic seemed eager to keep adding things to my bill, more shots, more prescriptions, so i'm looking for an alternative.
