Antiviral Medicines Medication
Several: This depends first upon the correct diagnosis - have your lesions been diagnosed as Herpes? The antivirals vary from topical drops for Herpes in the eye, to pills like Valtrex (valacyclovir) for systemic treatment and a few intravenous medications for severe Herpes. You should be under a physicians's supervision for this condition. ...Read more
Viruses: The definition of what is alive or not can be quite dicey. If one defines life as the ability to replicate oneself outside a cell, the viruses are not alive. They often do replicate quite well inside of host cells using its genetic code, either dna or rna, to 'brainwash' the cell into making lots of virus, an acquired genetic disease. Antivirals inhibit the viral replication process. ...Read more
They don't: Most antviral drugs suppress replication of viruses without actually killing them. Examples include herpesviruses and hiv. Hiv therapy stops the virus from infecting new cells, but viral dna is still present in resting cd4 cells, and could create new virus if medications were stopped. That's why we can't yet cure hiv. ...Read more
Depends on the drug: Some antivirals have methods of action that are very specific for a viral enzyme or protein and not people. Many, however, have effects that also cause toxicity in mammalian cells since that is where the virus replicates. Even those that are fairly specific can have side effects. As an example, some HIV drugs like azt (zidovudine) inhibit viral reverse transcriptase that we do not have but are still toxic. ...Read more
Probably.: If you are already sick and it has been less than 48 hours since the onset of symptoms, an antiviral drug may help by Keeping you from getting seriously ill, or helping you feel better faster. If you have been exposed, an antiviral drug may be about 70 percent to 90 percent effective in preventing the illness. ...Read more
Sometimes helpful: If you have recurrent/chronic herpes you need to begin antivirals within 72hrs of first symptoms or you may be using daily doses as prevention. So stocking up could make sense. These antivirals are related to the drug Acyclovir which is very safe. Other antivirals may not be as safe or may require monitoring. So stocking up would not be wise. Important: always check expiration dates. ...Read more
VIRAL INFECTION: What kind of viral infection do you have? Please be guided by your md. ...Read more
Taking for what?: You should always be talking to the prescriber, and it depends on what kind of anti-viral drug. Are we talking Acyclovir or valcyclovir for herpes, or drugs for hepatitis c, or for hiv? Different anti-viral drugs have differing drug interactions. In general, hydrocodone does not have many drug interactions. If it is prescribed, talk to prescriber. If you don't have prescription, don't take it! ...Read moreSee 1 more doctor answer
Antibiotics: Both are considered antibiotics, but antivirals treat very specific viral infections. There are fewer of these and they have no efficacy against bacterial infections. Most antibiotics are designed to kill or damage the function of bacteria and have a wider range of activity against bacterial groups. ...Read more
HIV Fusion & Entry: In order for the HIV virus to enter CD4+ "Helper" Tcells, HIV glycoproteins gp120 and gp41 interact with the CD4+Tcell receptor and CCR5 and CXCR4 on the CD4+ Tcell. There are two FDA drugs that are either fusion or entry inhibitors. The reason these drugs are important is because some patients become resistant to the other classes and these can be used.

I was diagnosed with HIV last month. I will start antiviral drugs today. Is it be ok if i take spirulina with the drugs? Thanks in advance.
Sure: Don't expect any benefit. Spirulina is an old health fraud. I am very glad you are getting treated for your HIV infection. If you are interested in complementary therapies, find an evidence-based holistic physician in your community. He/she won't recommend spirulina. ...Read moreSee 1 more doctor answer

Hi, what are the antiviral drug for dengue virus spesifically the rna-dependant RNA polymerase as the potential target? Thanks
None yet: Dengue fever and its severe form, dengue hemorrhagic fever, have no cure nor vaccine. One path of research is to find a way to use nucleoside analogs to block the viral rna-dependent RNA polymerase (coded by ns5), which copies the viral genetic material. So far, no drug has been approved yet. Not sure if anyone has found and submitted such a drug to the fda (food and drug administration). ...Read more
What are the risks of contracting HIV from becomg a phlebotomist? What antiviral drugs are available if i got stuck with a needle by infected patient?
HIV: Despite the best precautions, anyone carries the risk of a needle stick in your profession. If indeed one gets stuck, there is a protocol to be followed. Please inquire from your school or hospital. Hope that helps. ...Read more
Unlikely: Since exposure chicken pox, the virus is already replicating days before pox are noted. This is ample time for a person's immunity to start making antibodies. Recurrence of cp is more likely to be based on an individual's innate immunity when they first acquire the infection and later health. Rx needs to be started in 24 hours after pox appear, and important if newborn or other health issue. ...Read more

I have shingles it’s been a week and a half I finished my antiviral medication 2 days ago and my pain in back is this normal?
Shingles : This is not unusual as the nerve root has been inflamed and,unfortunately, postherpetic neuralgia may be a chronic condition. At this time I would ask a neurologist if a course of corticosteroid medication may be worthwhile. However it is not unusual for a typical case of shingles to have pain lasting a few weeks and then resolve. ...Read more
Warts: Each night before going to bed soak a cotton ball in apple cider vinegar, apply it to the wart and then hold it in place with a band-aid. Leave it on all night, or if you like, 24 hours a day but change the soaked cotton and band-aid each evening for a week. The wart will swell and may throb as it reacts with the vinegar and then start to turn black within the first two days and in two weeks gone. ...Read moreSee 1 more doctor answer
No: Medications are specific to the cause. Antivirals are for virus infections, antibacterials are for bacterial infections, antifungals are for fungal infections and so on. I do not believe that your pcp or other physician would inted to treat you for a parasitic infection with an antiviral. There may be some confusion on what you have or what you are taking or there may me more to the story. ...Read moreSee 1 more doctor answer
Different bugs: Anti viral medications are only effective for specific viruses (we have far fewer of these). The remainder of the antibiotic classes are indicated for a range of bacteria. Antifungals are considered a type of antibiotic but (you guessed it) attack the cell walls of fungii. ...Read more
Yes: This would depend on the specific drug, but the most common antiviral medications used in pregnancy are valcyclovir (valtrex) and acyclovir, both of which target the herpes viruses. They are both safe and can reduce your risk of a herpes outbreak around the time of delivery, which can be dangerous to a newborn. Tamiflu (oseltamivir) should be limited to known flu infection or exposure in the high risk. ...Read moreSee 1 more doctor answer
Take meds: Hiv can develop resistance by replicating (multiplying) when there are antiviral drugs present. The way to prevent this is to always maintain high enough drug levels to completely prevent replication. People who take their medications faithfully rarely develop resistance, as long as the drugs are chosen properly. ...Read more
I have shingles. What are the chances of my 3yr old and 17.5mth old getting it? 17.5mth old had 18mth shot today early. I'm on antiviral medication
Depends on situation: Shingles is a re-activation of the chickenpox virus that hibernates in your nerve roots after you had it or the shot.For unknown reasons, it reactivates and causes the localized rash/pain. The blisters do contain virus, which could give your kids chickenpox. If they were vaccinated, that is unlikely. Covering the sores and hand washing prevents spread of the virus.The kids would not get shingles. ...Read more
HSV: Herpes type 1 and 2 are chronic viral illnesses that have active and dormant phases. In an immunocompromised patient, it can become a disseminated disease. It can be fatal to a newborn if mother has active lesions and baby is delivered vaginally. Treatment includes Acyclovir which is a well known drug used for decades. Please speak to your physician about side effect profile of drugs and herbs. ...Read more
