PrEP: Protecting Yourself Before HIV Exposure

You probably don’t expect to have a car accident every time you drive.

Yet you still fasten your seatbelt.

Not because you expect something bad to happen—but because you understand that some risks are impossible to predict.

PrEP works on exactly the same principle.

It is one of the most important medical advances in HIV prevention over the past two decades, giving people the opportunity to protect themselves before exposure occurs.

At Catalyst Men’s Clinic, we believe prevention should never be associated with fear or judgement. Instead, it should be viewed as another way of taking responsibility for your health.

What Is PrEP?

PrEP stands for Pre-Exposure Prophylaxis.

It is medication taken by HIV-negative individuals to reduce the risk of acquiring HIV before they are exposed.

Unlike HIV treatment, which is prescribed after infection has occurred, PrEP works by maintaining protective drug levels in the bloodstream that prevent HIV from establishing infection if exposure occurs.

Today, PrEP is recommended by major health organisations including the:

  • World Health Organization (WHO)
  • U.S. Centers for Disease Control and Prevention (CDC)
  • International Antiviral Society (IAS)

How Effective Is PrEP?

PrEP is among the most effective preventive medications available in modern medicine.

Clinical studies have consistently demonstrated remarkable results.

The landmark iPrEx Trial, published in the New England Journal of Medicine, first demonstrated that daily oral PrEP significantly reduced HIV transmission among people at increased risk.

Subsequent real-world studies found that when taken consistently, PrEP reduces the risk of acquiring HIV through sexual contact by approximately 99%.

More recently, long-acting injectable PrEP has shown similarly impressive protection while eliminating the need for a daily tablet.

The evidence is now so strong that PrEP has become a standard part of HIV prevention programmes around the world.

Who Should Consider PrEP?

Many people mistakenly believe PrEP is only intended for people with multiple sexual partners.

That simply isn’t true.

You may wish to discuss PrEP with your doctor if you:

  • Have recently started a new relationship
  • Are returning to dating after divorce or separation
  • Travel frequently
  • Have sexual partners whose HIV status is unknown
  • Have a partner living with HIV
  • Prefer an additional layer of protection
  • Simply value taking proactive care of your health

The decision to start PrEP isn’t about labels.

It’s about making informed choices.

How Is PrEP Taken?

There are currently two main approaches.

Daily Oral PrEP

One tablet is taken every day.

This remains the most widely used option worldwide.

Daily PrEP offers continuous protection provided it is taken consistently.

Long-Acting Injectable PrEP

Some countries now offer injectable PrEP using cabotegravir.

Rather than taking a daily tablet, an injection is administered approximately every two months.

For suitable patients, this can be a convenient alternative.

Does PrEP Protect Against Other Sexually Transmitted Infections?

No.

PrEP only protects against HIV.

It does not prevent:

  • Gonorrhoea
  • Chlamydia
  • Syphilis
  • Genital herpes
  • Human papillomavirus (HPV)
  • Hepatitis B or C

Depending on your circumstances, condoms and regular sexual health screening remain important components of staying healthy.

Is PrEP Safe?

For most healthy individuals, PrEP has an excellent safety profile.

Some people experience mild side effects during the first few weeks, including:

  • Mild nausea
  • Headache
  • Temporary stomach discomfort

These symptoms usually resolve without treatment.

Because PrEP is prescription medication, your doctor will arrange:

  • HIV testing before starting treatment
  • Kidney function blood tests
  • Regular follow-up reviews
  • Ongoing HIV screening

This monitoring helps ensure treatment remains both safe and effective.

Why Speak to a Doctor Before Starting PrEP?

PrEP is not simply a prescription.

It forms part of a broader sexual health programme.

A consultation allows your doctor to:

  • Confirm that PrEP is appropriate for you
  • Discuss your individual risk factors
  • Screen for HIV and other sexually transmitted infections
  • Review kidney function
  • Answer any questions confidentially

At Catalyst Men’s Clinic, consultations are conducted in a professional, discreet, and judgement-free environment.

Prevention Is a Sign of Responsibility

There is an outdated misconception that seeking PrEP somehow reflects risky behaviour.

In reality, the opposite is true.

People who seek preventive healthcare are taking responsibility for themselves and for their partners.

Just as we wear seatbelts, purchase insurance, and attend regular health screenings, PrEP represents another evidence-based way of reducing unnecessary risk.

Good healthcare is rarely about reacting to problems.

It is about preventing them whenever possible.
