Effectiveness
How Viread Affects PatientsTenofovir is an antiviral medicine used to treat HIV-1 and Hepatitis B infections. Lab tests show that it works by stopping the virus from making copies of itself. It was found to be effective with a concentration of 0.04 to 8.5 micrometers. Taking tenofovir with other antiviral medications has been shown to have an additional or synergistic effect in preventing the virus from replicating. Tenofovir has been approved by the FDA to treat HIV-1.
How Viread works in the bodyTenofovir is a medication used to treat HIV. It works by blocking an enzyme that helps the virus replicate, limiting its spread and allowing the virus to be managed. Tenofovir is absorbed in the body and converted to its active form, tenofovir diphosphate. This active form competes with natural deoxyribonucleotide substrate for binding to HIV-1 reverse transcriptase and hepatitis B polymerase, which then stops the virus from copying itself. In rare cases, HIV-1 may develop a resistance to tenofovir, meaning the virus can still replicate even with treatment.

However, female mice had an increase in liver adenomas at a higher dose. Pregnancy: Tenofovir disoproxil has been assigned to pregnancy Category B. Animal studies have found no harm to the fetus, but there are no adequate studies

Viread Reviews: What are patients saying about Viread?
5Patient Review
11/18/2012 Viread is much easier to take than Intron A, however I have experienced some negative side effects such as poor appetite and constant joint popping. Additionally, I am concerned about the lack of information available regarding pregnancy while taking this medication.
5Patient Review
4/28/2012 I've only been taking this medication for a month, and I seem to catch colds really easily. Can I take a liver care alternative medication at the same time? I have also stabilized my sorrosis and gotten rid of my rashes.
5Patient Review
11/9/2015 I was positive for Chronic Hbv in 1990 and started a double-blind study for a new drug. I ended up being given Hepsera, but my viral load skyrocketed after the completion of the study. I started taking Viread and lamivudine, then switched to Viread 300mg and Baraclude (1mg, then .5mg). My viral load has been undetectable and my liver tests have been somewhat normal for over 7 years.
5Patient Review
1/8/2015 I've been feeling really terrible lately and my blood tests aren't improving. I'm considering quitting this treatment, but I don't know if the benefits will outweigh the bad side effects.
5Patient Review
4/24/2014 Though I experienced some daily side effects, such as a low-grade fever, body aches, dizziness, nausea, headaches, and nightmares, this treatment was ultimately effective.
5Patient Review
2/16/2015 No unpleasant side effects that I've noticed. In just three months, the treatment was undetectable in my system. The only downside is a dull pain on my right side occasionally.
5Patient Review
2/20/2015 I have chronic hepatitis B and have been taking this medication for over a year. My viral load has gone from 2 million to undetectable. I haven't experienced any negative side effects, but my vitamin D levels are on the low end of normal. So, I'm taking D to get the level up. There is also evidence that good levels of D can help prevent melanoma, which I recently had. Overall, I'm very pleased with the results except for the effect on my wallet!

9/5/2015 I've been taking this medication for over five years and it's been great. My only complaint is that it sometimes makes me itch, but other than that I haven't had any issues.
4.3Patient Review
10/23/2009 I've been on Viread for a little over five years now, and it's working well for me in combination with Ziagen and Sustiva. The side effects are tolerable; I have mild lipodystrophy around my waist, high triglycerides, low good cholesterol, and high bad cholesterol. However, being undetectible is more important to me.
4.3Patient Review
4/2/2017 I've been using this medication for two years and it's done wonders for my health. That said, I am now experiencing extreme thirst, bone pain, weakness, and shortness of breath. I'm not sure if skipping a day here or there would help, but I definitely feel like my bones aren't as strong as they used to be.
4.3Patient Review
2/9/2014 I've been taking Viread for a year now and it's working great. I'm undetectable. But I'm wondering what will happen if I stop taking the medication or how long I have to take it for. My doctor says I have to take it for the rest of my life, but is that really true?
4.3Patient Review
2/3/20084Patient Review
4/22/2014 I've been taking this drug for a little over two months. I started experiencing some vomiting and nausea, but it's manageable. It can be hard to fall asleep sometimes, but I'm still active with sports. So far the viral count has dropped from 14million to 163IU/mL, which is good progress.
4Patient Review
6/22/2013 I've been taking Viread for two years and it's done a great job controlling the virus with relatively few side effects. The only issues I have are cold hands/feet, weird dreams, and occasional trouble sleeping; however, these are manageable.
4Patient Review
10/9/2014 I've been taking Viread 300mg daily since my liver transplant in 2010. I had chronic Hep B which turned into cancer, but this medication has helped me a lot. The only downside is some occasional heart palpitations, cold hands/feet, and diarrhea.
