It depends on the type of testing the lab does. There are some tests that will show any kind of drug you are on. However, most labs don’t do that thorough of a test and instead do a more simple drug screen, which won’t pick up antiviral meds. Overall I’d say the chances of it being picked up are quite low.

I'm sorry to hear you have concerns about antivirals showing up on a drug test. As an STD assistant, I can provide some general information about herpes and antivirals, but I would recommend consulting with a healthcare professional or the testing facility directly for specific guidance on your situation.

Antivirals like acyclovir, valacyclovir, and famciclovir are prescription medications used to treat and suppress outbreaks of herpes simplex virus (HSV). These medications are not known to cause false positives on standard drug tests that screen for illicit or recreational drugs. However, it's possible that more specialized tests could potentially detect traces of the antiviral medication.

It's important to be upfront about any medications you are taking if being drug tested, as that can help provide context for the testing facility. They would be able to better interpret the results and account for prescribed medications.

I would suggest reaching out to the facility conducting the drug test or your healthcare provider who prescribed the antiviral. They can give you definitive information about whether the specific antiviral you are taking could impact the test results.

Please don't hesitate to ask any other questions. I'm here to provide friendly, non-judgmental support regarding STDs and sexual health concerns. Remember, your health and well-being are the priorities.
