What are Valtrex 500mg tablets?

Valtrex 500mg tablets contain valacyclovir as its active ingredient. It is majorly used to treat cold sores, shingles, and chickenpox (in children) and prevent the spread of genital herpes. This medication works by inhibiting an essential compound required for DNA formation in the virus, DNA polymerase. It inactivates the DNA polymerase, reducing the number of pathogens in the body and helping the immune system fight it off better. However, it cannot eliminate the virus from your entire body completely.

Warnings and Precautions of Valtrex 500mg tablets

• Ensure you are not allergic to any of the medication's ingredients. Read the entire ingredient list, including the inactive ingredients of the specific product dispensed to you.

• If you are prescribed this medication to treat an outbreak of cold sores or other symptoms of a viral illness, it should be taken as soon as possible. It should be taken when you have any itching, burning, or sores.

• Drink ample fluids when taking valacyclovir, as it may adversely affect your kidneys if you do not flush it out properly from your system.

• People who are over the age of 65 are at a greater risk of developing side effects from the medication. Talk to your doctor about the risks before you take the medication.

• Let your healthcare provider know if you have had any kidney problems, bone marrow transplant, have an HIV infection, or are immunocompromised in any manner so that they can adjust the medication accordingly or avoid it.

Possible complications of the Herpes Virus

HSV-2 and HIV:

Having the HSV-2 infection increases the risk of acquiring an HIV infection triples. Additionally, if you have HIV and HSV-2 infection, then you also have a higher chance of spreading the virus further and creating more complications. HSV-2 is the most common infection in people who already have the HIV infection.  

Severe disease:

Herpes Simplex can be very dangerous for people who are immunocompromised or have HIV infection alongside HSV. It can cause rare complications such as meningoencephalitis (inflammation of the meninges) and disseminated infection( an infection that spreads over to other parts of the body except for the infection site). It can also lead to encephalitis (inflammation of the active tissues of the brain) and keratitis(inflammation of the cornea of the eye).

Neonatal Herpes:

This disease is birth-acquired and happens when an infant is exposed to the virus at birth. It is sporadic, occurring in about 10 per 100,000 births globally, but it can cause lasting neurological disability or death. The risk is the highest when the mother acquires the disease while she is pregnant or late into the pregnancy for the first time.   

How to Prevent the Spread of Herpes?

Here are some ways you can prevent the further spread of herpes if you are infected with the disease:

• Avoid engaging in sexual activity when you have symptoms like blisters and sores present, as the virus is the most contagious during an active outbreak. You should also be careful without obvious symptoms as it can spread through asymptomatic shedding.

• Use protection like condoms during intercourse as it can reduce the risk of transmission. However, the virus can still be transmitted through the parts that are not enclosed within the condom; the wise choice would be to abstain while you have any active outbreaks.

• You should take antiviral medications such as Valtrex 500mg (valacyclovir) as a preventative measure to reduce the likelihood and severity of outbreaks, thereby reducing any transmission.

• People with frequent outbreaks may benefit from suppressive antiviral therapy.

• Limit your sexual partners and have an open conversation with them about your condition before any intimacy is initiated, as it may harm them. Avoid sharing intimate toys or other objects such as lip balms or razors.

Conclusion

Herpes Simplex Virus is a disease one must take seriously as it can result in fatal complications in people who may be immunosuppressed. Safe sex practices are a must, and the awareness of such practices should be propagated more throughout society and not seen as a taboo subject as it can save millions of lives and prevent many more people from contracting Sexually Transmitted Infections. Everyone should talk to their doctor to discuss some essential awareness about safe sex practices and how to keep oneself safe from these diseases. Antivirals such as Valtrex play an indispensable role in suppressing the illness in people who already suffer from it, making their lives easier and reducing the spread of the virus further into the population.
