Tenofovir disoproxil and telbivudine are categorized as class B regarding safety in pregnancy and the other HBV drugs as class C. Lamivudine and tenofovir disoproxil have not been shown to be associated with fetal abnormalities even when used during the first trimester of pregnancy.[73] (extracted from an article in Nature by Prof. Anna Lok]
3. So, I think Lamivudine is safe. You must consult your doctors, including your Obstetrician, they must work as a team to look after you and your baby.
Baraclude (Entecavir) is a class C drug for pregnancy, Tenofovir is class B. Doctors do not recommend Entecavir during pregnancy, so you may have to stop Entecavir if you are planning to have a baby. Tenofovir is recommended during the third trimester and many women had also taken it during the whole of pregnancy. Talk to your doctor.
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. You should discuss your concerns with the doctor who prescribed PEP or a pharmacist/chemist. I wish you the best.

Just talked to my doctor and he said it was not the drug causing this symptom and Lactic Acidosis from these drugs does not occur. He said it is a class warning but is not really relevant for these medications. Hmmm
Hoping it's just the darn cold air we are getting. I usually tolerate cold pretty well too!
it is a failed hiv drug, this is the clear strategy drug makers had at 2000, use of failed hiv drug on hbv to make mutants (instead using tenofovir which makes no mutants) and then find always new drugs with patent and high price for the mutants......
That is actually not much better than tenofovir vs tenofovir disoproxil fumarate, the actual substance in Viread. It is 50 times more potent than tenofovir.
It is all this improper simplification of callling viread tenofovir.
Tenovovir, if it would be given orally, would have no effect on HBV.
TEnofovir if given intravenously or sc would still have almost no effect on HBV in the liver. the substance has a high negative charge and cannot easlily penetrate cell membranes.
(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 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.
