The end of a 28-day HIV PEP prescription creates a practical question: what comes next if you want ongoing HIV prevention? PEP is emergency medication used after a possible exposure. PrEP is prevention used before potential exposure. CDC's 2025 recommendations describe a transition to PrEP after completing PEP for people who may have continuing HIV exposure risk; a routine gap is not necessary when a clinician determines that the transition is appropriate.
This is not a self-directed drug-switching guide. The clinical team must confirm your HIV testing plan, assess the medicines and determine the appropriate PrEP regimen and timing. Your job is to make sure access, appointments and coverage do not collapse at the handoff.
Don't wait until the last PEP tablet to make a plan
Call the clinician or clinic that prescribed PEP and say you would like to discuss ongoing HIV prevention. Ask whether it can provide PrEP directly or refer you to a provider with continuity of records. Clarify who is ordering follow-up HIV tests and who will review the results. An online PrEP service may be convenient, but its new-patient intake, lab process and insurance checks can take longer than a person expects.
If the original clinic cannot continue care, request the discharge summary, medication list, prior test dates and recommended follow-up schedule. You can share these securely with the next licensed clinician. A new provider may still need additional testing; a copy of a previous negative result does not automatically satisfy all clinical requirements.
What does “no gap” actually mean?
CDC's nPEP clinical guidance says people who have ongoing exposure risk can transition to PrEP after the 28-day PEP course without a gap, under clinical care. It does not mean you should improvise doses, substitute leftover medication or skip follow-up HIV testing. The drug, testing history and possible symptoms matter. The clinician must decide whether immediate transition is appropriate and how HIV status will be evaluated.
Discuss this before the PEP course ends. If an insurance authorization or pharmacy shipment is pending, tell the provider rather than accepting an unplanned break in care. A clinician can assess alternatives and timing.
The transition appointment: six essential questions
- Have we scheduled the HIV tests recommended during and after PEP?
- Do I need any additional testing before starting a particular PrEP medicine?
- Should I use daily oral PrEP or ask about a long-acting injection, given my health history and preferences?
- How and when will my first PrEP prescription or injection be available?
- Which clinic will manage future testing, refills and questions about side effects?
- How will costs be covered for medication, visits, tests and any injection administration?
If you have symptoms that concern you or a possible new exposure, tell the clinician. Don't treat a symptom or test result as something to interpret through a generic web checklist; it may require prompt, individualized assessment.
Paying for the two phases may be different
PEP and PrEP can use different coverage and assistance arrangements. CDC identifies urgent medication-assistance pathways for some PEP patients, while ongoing PrEP may be covered under preventive-service insurance rules, manufacturer assistance, state programs or a clinic/telehealth arrangement. Do not assume approval for 28 days of PEP automatically funds months of PrEP.
For people with private insurance, ask the PrEP team whether it has verified the preventive medication and testing benefits. If uninsured, ask which assistance program covers the chosen drug and which separate program supports labs and visits. The manufacturer may fund medication while another organization pays for clinical services. See the program-status tracker.
Choosing an ongoing PrEP provider
A new provider should explain the testing schedule, the drug options appropriate for your circumstances, how its refill process works and what to do if you are late for a visit. Telehealth can be convenient for oral PrEP, but an injectable medication still requires an in-person administration site. Confirm the location and benefit verification before relying on an injection plan.
Compare providers on FreePrep's comparison page, or start with the eligibility tool. If you use a provider that advertises $0 services, verify whether that promise includes your insurance category, particular pharmacy and lab work.
What if you missed the follow-up appointment?
Contact your prescribing clinician promptly. They can determine which HIV tests are due and the appropriate next steps. Do not guess that you are fully protected simply because you previously completed PEP, and do not begin old prescriptions without individualized advice. If a new exposure may have occurred within the preceding 72 hours, seek immediate professional evaluation for PEP rather than waiting for a routine follow-up appointment.
A simple timeline with the right questions
The following is a conversation timeline, not an instruction to change medications yourself. A clinician must confirm HIV status, assess ongoing risk and select the appropriate prevention regimen.
| Stage | Patient question | Why it matters |
|---|---|---|
| Beginning of the 28-day PEP course | Who is scheduling my follow-up? | Prevents a handoff from being lost |
| During PEP | What should I do if I have side effects or cannot fill all doses? | Medication adherence and clinician support matter |
| Before PEP ends | Am I a candidate for ongoing PrEP, and what testing is required? | CDC supports a prompt transition for people with ongoing exposure risk |
| At the transition | Who will prescribe and cover the next medication? | An enrollment page is not the same as an active prescription |
| Later follow-up | When do I need further HIV testing? | An initial negative test cannot rule out every recent infection |
The “no gap” phrase needs context
CDC notes that a gap is not required between completion of a 28-day PEP course and starting PrEP for people with ongoing indications. That does not mean every patient can begin any PrEP drug without further assessment. Recent exposure, test results, medication choices, interactions and the specific requirements for oral or injectable PrEP all matter. A person who recently took PEP may need particular HIV testing and clinical follow-up. Avoid treating a general guideline as a personalized prescription.
If you hope to move to long-acting injectable PrEP, make sure the injection site, testing and product coverage are arranged in advance. A clinician may advise another prevention approach while that is organized. No comparison site should suggest self-bridging regimens or using leftover PEP medication.
Make the handoff between clinics visible
Write down the name and phone number of the PEP prescriber, the next appointment date, the destination pharmacy and the HIV testing plan. Ask whether records can be securely transferred. If the ongoing PrEP provider is a telehealth service, confirm that it can review the recent PEP course and that the laboratory process fits your situation. If it cannot, an in-person prevention clinic may be the safer starting point.
Questions to ask about payment
PEP and PrEP are not interchangeable billing categories. A plan may process a PEP emergency visit under one set of benefits and preventive PrEP under another. Confirm each cost separately: the PEP course, baseline and follow-up testing, PrEP medicine, clinic visit and future refills. If uninsured, ask about both medication assistance and clinic/lab assistance.
If something goes wrong with the transition
Missed your appointment? Contact your clinical team promptly rather than assuming the original PEP course provides ongoing protection. Lost a prescription? Ask the pharmacy and prescriber to help with the actual medication access issue. Developed symptoms concerning for recent HIV infection? Contact a clinician for appropriate testing and assessment. The right next step depends on clinical facts, not an online algorithm.
Frequently asked questions
Can PrEP start the day after finishing PEP?
CDC guidance allows transition without a routine gap when clinically appropriate, but the clinician must determine the regimen and testing plan for you. Do not choose the date yourself.
Does completing PEP guarantee I do not have HIV?
No. Follow-up HIV testing remains important. Ask your clinician when testing is recommended and how to interpret results.
Can a mail-order PrEP program replace my PEP provider?
It may be able to manage ongoing PrEP after intake and appropriate testing, but do not assume an online signup can handle a time-sensitive PEP emergency or an immediate transition.
