What to know about PrEP
PrEP is medication you take before sex or sharing a needle to protect yourself from HIV. PrEP is for people of all genders and more than 99% effective against HIV when taken as directed.
PrEP comes in the form of a pill or a shot. You can take it even if you drink alcohol, use drugs, take hormones, or use birth control.
Learn about each type before deciding which one is right for you.
How to take PrEP as a pill
PrEP pill types
At City Clinic, we will recommend one of these two pills based on your medical history and what coverage you qualify for.
- Truvada, available as either a brand-name or a generic medication
- Descovy, only available as a brand-name medication
PrEP pill schedules
You must take your PrEP pill on schedule for it to work. There are 2 schedules people use:
1. Take 1 pill every day
- Taking 1 pill of PrEP every day works for all genders.
- It also works for all body parts used for sex, and for protection during injection drug use.
- If you miss a pill on this schedule, take it as soon as you can.
- If it is almost time for the next pill, just take that next pill.

2. Take pills before and after sex only (the 2-1-1 schedule)
- You can only take the 2-1-1 schedule with Truvada, not Descovy.
- People can use the 2-1-1 schedule to prevent HIV when having sex using their penis or butt/anus.
- The 2-1-1 schedule is not known to work against HIV when using your vagina/front-hole for sex.
- On the 2-1-1 schedule, you take pills only on the days when you have sex, and for two days after.
- You must follow the schedule correctly for it to work.
- The schedule is very specific:
- Take 2 pills at once 2 to 24 hours before sex, and then a second dose of 1 pill, 24 hours after the first dose. Finally, take a third dose of 1 pill, 24 hours after the second dose.
- Keep taking one pill every day until 2 doses have passed since your last sex. For example, if you have sex again between the second and third doses, add a fourth dose of 1 pill 24 hours after the third dose. If you have sex between the third and fourth doses, or between any later doses, keep adding more doses on this same schedule until you have had two doses without any sex in between.
- If you are more than 2 hours late for a dose, take 2 pills in a single dose and call your provider about getting PEP.
- The 2-1-1 schedule requires planning ahead. Some people also find it hard to follow. If the 2-1-1 schedule does not work for you, consider taking PrEP as 1 pill every day instead.

How to take PrEP as a shot
PrEP shot types
- Cabotegravir: 1 shot every 2 months. The brand name of cabotegravir is Apretude. It is only available as a brand-name medication.
- Lenacapavir: 1 shot every 6 months. The brand name of lenacapavir is Yeztugo. It is only available as a brand-name medication.
PrEP shot information
- Taking the shot
- The shot must be given by a medical provider.
- You cannot do the shot yourself or have a companion do it for you.
- You cannot pick the shot up at a pharmacy.
- You must get the shot on time. Otherwise, it stops working to prevent HIV.
- Side effects
- Pain and other side effects around the place the injection is given can happen with both cabotegravir and lenacapavir.
- But those side effects can be different, because the two medications are injected differently from each other.
- Availability
- PrEP as a shot is not as widely available yet as the pill forms of PrEP.
- This is because PrEP as a shot is newer, and doctors’ offices have to set up a system for getting the shot delivered and stored at their office.
- The pill forms of PrEP are simpler for any doctor’s office to prescribe, because they only have to send the prescription to a pharmacy.

PrEP is for people of all genders
You have options for PrEP no matter your gender or what kind of sex you have.
Choose the right type of PrEP for you
Your provider can help you with making the choice between the pill or shot. Here are some questions to consider and help you decide:
- Which option works best for your schedule and routine?
- Can you take time off work if the shot makes you too sore?
- Does your health coverage cover injectable PrEP?
- Which clinics have injectable PrEP?

PrEP does not prevent other STIs
Here are ways you can protect yourself against sexually transmitted infections (STIs):
Doxy-PEP
Take the antibiotic doxycycline after sex to prevent getting a sexually transmitted infection (STI). It is like a morning-after pill but for STIs.
Vaccines against STIs
We offer several vaccines that can prevent infections spread through sex. These vaccines are safe and work well.
Condoms
Condoms are highly effective when used correctly and consistently during sex. You can get free condoms during City Clinic visits.
