What does taking PEP involve?

Taking PEP will normally involve a four week course of two drugs. For PEP to be effective you need to commence treatment within 72 hours of an exposure to HIV.

Does PEP work?

It is believed taking PEP can prevent HIV, however the evidence is not conclusive. Taking PEP does not guarantee that you won't become HIV positive. It is offered as a last resort. Safe sex and safe injecting are still the best way to avoid HIV.

Where can I get PEP?

You can be assessed for PEP at sexual health clinics, doctors (including some general practitioners) who specialise in HIV/AIDS, and hospital accident and emergency departments (which are open 24 hours). If possible, seek assistance from a doctor who specialises in HIV or sexual health clinic first.
If you would like further information about PEP or have other questions you would like answered you can call 1800 PEP NOW (1800 737 669). The service operates 24 hours.

How much does PEP cost?

As with any prescription drug there will be a cost involved. Normally a four weeks' supply of one drug will cost $22.40. Keep in mind your doctor is likely to prescribe a course consisting of at least two drugs.

In taking PEP, what difficulties may I encounter?

Taking PEP requires strict adherence to the dosing instructions. You will need to take the drugs as directed by your doctor. Missing doses or not completing the four week course will reduce the chances of the treatment working.
The drugs have a number of potential side effects. While some people experience no side effects at all, most probably experience some mild to moderate side effects.
Side effects might include nausea, rash, headaches and fatigue. Your doctor will provide you with information on side effects and you need to also read the drug company information that is provided with the drugs.
You need to monitor the side effects and seek medical assistance if you feel you can't cope with the side effects.

What happens once I finish PEP?

It is important once you have finished the four week course that you return to your doctor. Your doctor may want to see you at the end of the first month, third month and six month. The reason for follow-up sessions is to check the impact of PEP and its effect on you. Remember PEP has not conclusively been proven to work and therefore follow-up is essential.

Do I need to practise safe sex and safe injecting?

Yes. There is no conclusive evidence that PEP always works. There is also no evidence to suggest that if you have another exposure to HIV while taking PEP that you will be protected. Safe sex and safe injecting are still the best methods to protect you from HIV.
