HIV PrEP side effects, kidney checks and bone health
Most people tolerate oral PrEP, but nausea, headache and small kidney or bone changes are reasons for planned monitoring.

Oral tenofovir disoproxil/emtricitabine PrEP has a well-established safety profile, but it is still prescription medicine. Baseline and follow-up checks are designed to find uncommon problems early, not to suggest that harm is expected.
Common early effects
Some people report nausea, loose stools, headache, tiredness or abdominal discomfort when starting. These effects are often mild and settle, but persistent vomiting or difficulty taking doses needs advice. The exact leaflet lists the frequency and full range of effects for the dispensed product.
Kidney monitoring
Tenofovir disoproxil is cleared through the kidneys and can rarely reduce kidney function or affect the renal tubules. A clinician checks kidney markers before prescribing and at intervals based on age, baseline results and other risks. Anti-inflammatory painkillers and other kidney-affecting medicines should be disclosed rather than assumed safe.
Bone considerations
Small reductions in bone mineral density have been observed with tenofovir disoproxil in some users. The clinical importance varies. Previous fractures, osteoporosis risks, low body weight or long-term steroid use may influence the discussion. Do not add high-dose supplements without checking; exercise, nutrition and choosing the right PrEP formulation or pathway are more nuanced.
When to seek help
PrEP must not be started or restarted without excluding HIV infection at the appropriate time. Fever, rash, sore throat, swollen glands or a flu-like illness after a recent exposure may be signs of acute HIV and need prompt testing. A very recent high-risk exposure may call for urgent post-exposure prophylaxis instead; PEP is time-sensitive and should be assessed immediately.
What to prepare for a medical review
A PrEP review covers recent exposures, the timing and type of HIV tests, kidney function, hepatitis B status, other medicines, pregnancy where relevant, and a wider STI screen. Follow-up testing is essential even when you feel well. Protection depends on taking the agreed schedule correctly, and national access pathways can differ across Europe.
A calm next step
Attend monitoring even when you feel well and report reduced urination, marked weakness or unexplained bone pain. If one PrEP option is not suitable, ask what approved or locally available alternatives exist.
