I am pregnant. If I have hsv1 antibodies why would my doctor prescribe antivirals?

I am pregnant.  If I have hsv1 antibodies why would my doctor prescribe antivirals?

Not ypical : About 80-90% of people have hsv 1 antibodies. This is different from hsv 2 (genital herpes). Unless you had evidence of a genital hsv 1 infection (possible but rare) then antivirals would not typically be prescribed. For those with a history of genital herpes then antivirals are usually started around 35-36 weeks for prevention. ...Read more

Is it safe to take antiviral medications while pregnant?

Is it safe to take antiviral medications while pregnant?

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 should be limited to known flu infection or exposure in the high risk. ...Read more

What are the effects of antiviral drugs?

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 inhibit viral reverse transcriptase that we do not have but are still toxic. ...Read more

Why is naegleria fowleri way more deadly than viral and bacterial forms of meningoencephalitis ? And why doesn't it have a treatment?

Why is naegleria fowleri way more deadly than viral and bacterial forms of meningoencephalitis ? And why doesn't it have a treatment?

Similar to humans: Naegleria fowleri is a eukaryotic protozoan. Humans are also eukaryotes, which means our DNA and general cellular structure is very similar. Antibiotics and antiviral medications are effective because they can target components of cells that are different than ours. However, with Naegleria, given that they are so similar it is difficult to target them specifically and leave our own cells alone. ...Read more
