Why Can You Claim for PEP Side Effects After a Needlestick?

In a needlestick injury claim, the employer’s negligence caused the chain of events that made PEP necessary. Under the Health and Safety at Work Act 1974, employers must provide safe sharps procedures, proper disposal equipment, and adequate training. When they fail and a needlestick occurs, every consequence flows from that failure — including the side effects of treatment you had no choice but to undergo.

This is the element that often gets missed. PEP gets mentioned in passing — a sentence or two about treatment — but it isn’t always claimed as a separate head of damage with its own value. We do claim it separately. After 19 years handling workplace injury claims, we know that PEP side effects cause real suffering that deserves real compensation. Not a footnote. A specific, itemised element of your claim.

The legal position is clear. Your employer’s failure created the need for PEP. PEP caused side effects. Those side effects are compensable — regardless of whether they’re common or expected. You don’t need to prove the medication was incorrectly prescribed. You need to prove the needlestick was caused by negligence. That’s your employer’s problem, not yours.

What Is PEP and Why Is It Prescribed After a Needlestick?

Post-exposure prophylaxis (PEP) is a 28-day course of antiretroviral medication prescribed to reduce the risk of HIV infection after a needlestick injury. According to BHIVA (the British HIV Association), PEP reduces the risk of HIV transmission by approximately 80%. The standard regimen prescribed under NHS guidelines typically combines Truvada (emtricitabine and tenofovir disoproxil) with an integrase inhibitor such as dolutegravir or raltegravir (Isentress).

PEP must begin within 72 hours of the needlestick — ideally within hours. That urgency matters legally. You had no real choice about whether to take this medication. When a healthcare worker suffers a needlestick from a used needle, PEP isn’t optional. It’s medically necessary. And that necessity is precisely why its consequences are compensable.

The medication is powerful. It was designed to suppress viral replication. But that power comes with a cost to your body — and that cost has a compensation value that deserves to be properly quantified.

The 28-Day Reality — PEP Side Effects and Their Impact

PEP side effects affect the majority of users and range from persistent nausea to disabling fatigue. An Australian post-exposure prophylaxis study cited by Aidsmap (November 2025) provides the most detailed frequency data available: fatigue affects 37% of PEP users, diarrhoea 25%, nausea 24%, vivid nightmares or disturbed sleep 15%, and low mood or depression 10%. These are not rare reactions — they affect between one in four and one in three people taking PEP.

The numbers tell one story. The daily reality tells another. You’re nauseous every morning before a 12-hour shift. You’re so exhausted by midday that clinical work feels dangerous. You’re having vivid nightmares that replay the needlestick over and over. And you’re expected to carry on working — because nobody acknowledges that PEP side effects are an injury in their own right.

“I was incredibly nervous to make a claim as it was not something I have done before and wasn’t sure what to expect. However, even after my initial first call with Chris Carter I knew I was in safe hands. Chris was very transparent and honest with the information and guidance he gave throughout the entire process and made sure to explain anything I wasn’t sure about. Professional, honest and an all round excellent service.”

How Does PEP Affect the Value of Your Needlestick Claim?

Requiring PEP treatment increases the compensation value of a needlestick injury claim — see our full breakdown of needlestick injury compensation amounts to understand how PEP sits alongside the other heads of damage. PEP side effects are valued as a standalone head of damage — separate from the needlestick injury itself and any psychological trauma such as anxiety or PTSD. The exact amount depends on the severity of side effects, how long they lasted, and how significantly they affected your ability to work and carry out daily activities. Judicial College Guidelines provide the framework for valuing treatment-related suffering, and Carter & Carter apply these specifically to the PEP element of every needlestick claim.

The PEP element sits on top of compensation for the needlestick injury itself, psychological trauma, and any financial losses. Every claim is unique — the value of the PEP element depends on individual circumstances, including severity, duration, and impact on working life. Plus financial losses: lost earnings, travel to appointments, prescription costs.

“Dave has been brilliant from start to finish. He assured me about the process and kept me informed at every stage which resulted in compensation offer above my expectations.”

And remember — when claims settle without court proceedings (around 99% do), our fee is just 10%, not the 25% most firms charge. See exactly what you’ll pay.

PEP Side Effects and Work — Can You Take Time Off?

Lost earnings caused by PEP side effects are claimable as special damages — a separate financial head on top of the compensation for pain and suffering. If nausea, fatigue, or other side effects prevented you from working full shifts, reduced your hours, or forced you to take sick leave during the 28-day PEP course, those lost earnings form part of your claim. Your employer has a duty of care under the Health and Safety at Work Act 1974 — and that duty doesn’t disappear once you’ve been injured.

This is where a symptom diary becomes essential. Record every day: what symptoms you experienced, how severe they were (scale of 1–10), whether you worked a full shift, and if not, why. Note any tasks you couldn’t perform safely. If you’re a nurse struggling to draw blood because your hands are shaking from fatigue, that matters. If you’re a care worker who had to leave a shift early because of diarrhoea, that matters. Specific details make the difference between a general claim and a properly quantified one.

We also claim for travel costs to follow-up blood tests and Occupational Health appointments, prescription costs, and any other out-of-pocket expenses connected to the PEP treatment. These smaller amounts add up — and they’re yours to claim.

What Should You Do If PEP Side Effects Are Affecting You?

Do not stop taking PEP. Speak to your prescriber if side effects are severe — they can manage symptoms or adjust the regimen. Completing the full 28-day course is essential for protection. But while you’re going through it, there are practical steps that protect both your health and your claim.

Start your symptom diary immediately. Every day you record strengthens the PEP element of your compensation claim. Keep your PEP prescription details, Occupational Health referral letters, blood test appointment records, and any correspondence with your employer about the needlestick incident. If you’ve taken time off work, keep payslips showing reduced income.

Speak to a solicitor who understands PEP claims. We treat PEP side effects as a separate, quantified element of your compensation — not a footnote. Chris or David will assess your claim personally — including the PEP side effects element — and give you an honest view of what it’s worth. There’s no cost for this conversation and no obligation to proceed.

You’ve been through enough. The needlestick. The fear. The treatment. Don’t let the compensation process add to the burden. Start your needlestick injury claim online or call 0800 652 0586 to speak to Chris or David directly.
