What Is Pre-exposure Prophylaxis (PrEP)?
Pre-exposure prophylaxis (PrEP) is an important way to lower the risk of getting HIV. It works better to prevent HIV before infection rather than treating it after a person gets the disease.
The chance of recent HIV infections in high-risk people has been reduced with pre-exposure prophylaxis. However, PrEP only protects against HIV, not other sexually transmitted diseases or hepatitis.
Taking the medicine regularly is very important, as missing doses can reduce its effectiveness. PrEP uses special drugs (antiretroviral medicines) that lower the amount of virus in the body, making it harder to spread.
How Does Prep Work?
-
Pre-exposure prophylaxis (PrEP) lowers the risk of getting HIV by protecting both the individual and their partners from infection. It is meant for people who do not already have HIV.
-
There are two main antiviral medicines commonly used for PrEP. When taken consistently, they are highly effective in preventing HIV transmission.
-
The medications used for PrEP belong to a class of antiviral drugs called nucleotide reverse transcriptase inhibitors (NRTIs) and non-nucleotide reverse transcriptase inhibitors (NNRTIs). These medicines work by blocking the virus from making copies of itself inside the body.
-
If an individual is exposed to HIV or exhibits manifestations of an acute case, in that case, the individual will wait to confirm the negative test outcomes before resuming the pre-exposure prophylaxis medication.
-
Waiting for a negative screening result is significant because pre-exposure prophylaxis cannot cure HIV alone. Medication resistance may grow if pre-exposure prophylaxis is started during an HIV case.
How Effective Is PrEP?
PrEP medication works effectively if it is taken regularly. PrEP reduces the risk of contracting HIV by 99 percent. Among those who inject drugs, the possibility decreases by 72 percent.
PrEP will not prevent HIV infection if it is not taken consistently. PrEP for HIV does not prevent the spread of other sexually transmitted diseases, so individuals should use other means of protection when indulging in any sexual activity.
Individuals on PrEP should get tested for HIV once every three months, and regular follow-ups with the physician are a must.
Who Should Consider Taking PrEP?
People who can benefit from PrEP include:
-
Those who had anal or vaginal sex in the past six months.
-
People with a sexual partner who has HIV (with detectable or unknown viral load).
-
Individuals who do not always use condoms during sex.
-
Those who had a sexually transmitted infection in the past six months.
-
People who inject drugs or share needles or syringes.
-
Anyone who has needed post-exposure prophylaxis (PEP) multiple times or is at high risk of HIV exposure.
Is PrEP Safe?
PrEP is safe to use. PrEP to prevent HIV for females and males is a safe and effective way to protect at-risk individuals from getting the virus through sexual contact.
Individuals who are HIV-negative and have taken PrEP for five years did not report any negative effects on health.
Some may experience mild adverse effects, which may resolve on their own. If they persist for a longer time, individuals can discuss them with their physician.
What Are the Advantages and Disadvantages of Pre-exposure Prophylaxis Therapy?
Advantages of PrEP:
-
The drugs are effective in controlling HIV cases when consumed daily.
-
They can save an individual and their companion from HIV transmission.
-
It consists of one tablet taken daily at the recommended time, making it suitable.
-
It is discreet and permits individual management of prevention, which can be extremely empowering among individuals with increased possibilities of acquiring HIV.
-
It is a choice for individuals who desire to have a newborn.
Disadvantages of PrEP:
-
Dosages are required to be consumed daily without skipping.
-
Individuals are required to experience routine HIV screening (every three months).
-
It may not be right for an individual suffering from severe kidney disease or a history of hepatitis B (a liver disorder induced by the hepatitis B virus).
Is PrEP Right for You?
PrEP or pre-exposure prophylaxis, could be right for you if you are at high risk for exposure to HIV. You should consult with your physician to confirm whether the medication is suitable for you. The physician will also guide you on the type of medication you require.
Pre-exposure prophylaxis (PrEP) counseling plays a crucial role in HIV prevention. Before starting PrEP treatment, a healthcare professional can help individuals understand their risk of acquiring HIV and the various prevention methods available. They can also explain the benefits of integrating PrEP into daily routines.
Does PrEP Cause Side Effects?
Some expected side effects of both drugs are as follows:
-
Diarrhea (loose stools).
-
Exhaustion (tiredness).
-
Head pain.
-
Nausea and vomiting.
Rare but serious side effects of both include:
-
Rash (allergic reaction).
-
Liver and kidney issues.
-
Aggravating hepatitis B (a liver disorder induced by the hepatitis B virus) cases.
-
Lactic acidosis (excess amount of lactic acid in the blood).
Conclusion:
PrEP (pre-exposure prophylaxis) is a highly effective method for preventing HIV when taken as directed. Its success relies on both awareness and adherence.
The main goal of PrEP is simple: to stop HIV before it starts. It allows individuals to take proactive measures to protect themselves and their communities. When used consistently and with proper guidance, PrEP provides nearly complete protection against HIV infection. People who regularly skip their medicine doses will have an increased chance of developing HIV.
Pre-exposure prophylaxis for HIV was approved by the FDA (Food and Drug Administration) on July 16, 2012. To enhance PrEP effectiveness in HIV prevention, we need efforts like HIV education, testing, and awareness. These methods will help more people understand the benefits of PrEP.
Note from iCliniq:
-
PrEP is safe and effective. It prevents HIV when taken regularly under medical supervision.
-
PrEP should always be combined with regular testing, safe sex practices, and medical guidance for best results.
