PrEP does not protect against other STIs. Condoms can help prevent many of these though.

Although STIs are mostly easy to treat, symptoms can sometimes be unpleasant and sometimes serious. This is why regular STI testing is recommended.

The HPV vaccine reduces the risk of genital warts and cervical and anal cancers. Please ask your clinic or GP about this. Your clinic should also provide vaccines for hepatitis A and B if needed, and for mpox.

But if you routinely take other prescribed or over-the-counter meds, always tell your doctor (including your GP) that you are taking PrEP. Any pharmacist can also check for drug interactions.

Tenofovir (TD) should also be used with caution if you regularly take other drugs that affect the kidneys. These include some non-steroidal anti-inflammatory drugs (NSAIDs), especially diclofenac, ibuprofen and naproxen.

Routinely taking these drugs with PrEP can cause kidney problems. Avoid these meds when taking PrEP and please let your doctor know if you regularly need to take them.

TAF can interact with TB meds, anti-epileptics, St John's Wort and others. These interactions are not a problem with TD.

PrEP is very safe for trans and non-binary people taking hormone therapy (see p10).
