You feel a small bump on your arm. You look. A tick. Maybe attached, maybe walking across the skin. Either way, your brain skips straight to: what now?
Here’s the calm version of what to do, in the order to do it.
First 10 Minutes: Remove the Tick
If the tick is attached, get it off. Don’t wait, and don’t bother trying the home remedies you’ve probably heard about. Petroleum jelly, lit matches, alcohol while the tick is still attached. None of them work. They can also make the tick burrow deeper or regurgitate into the wound, which raises the risk of disease transmission.
Use fine-tipped tweezers if you have them. Grip the tick as close to your skin as possible, ideally at the head, not the body. Then pull straight up with steady, even pressure. No twisting, no jerking. The tick should come out intact within a few seconds.
If part of the mouth stays behind, don’t dig for it. Any remaining parts of the head typically work their way out or are absorbed within a few days.
Once the tick is off, wash the bite area with soap and water. Apply rubbing alcohol or another antiseptic. Wash your hands too.
Next: Don’t Throw the Tick Away
This is the step most people skip. Save the tick.
Drop it in a sealed plastic bag or small container. Stick the bag in the freezer. Snap a few photos of the tick on a piece of paper next to a coin for scale.
If you develop symptoms in the next few weeks, knowing what kind of tick bit you can shorten the diagnostic process. Some labs can also test the tick itself for the bacteria that cause Lyme disease, though this is more useful in research settings than in routine clinical care.
Write down the date. You’ll want it later.
In the Next 24 Hours: Consider Prophylaxis
Here’s where the timeline starts to matter. For a subset of tick bites, a single dose of doxycycline given within 72 hours can prevent Lyme disease.
The criteria are specific. The tick should be a deer tick (Ixodes scapularis), the one most commonly responsible for Lyme. It should have been attached for 36 hours or more. You should be in an area where Lyme is established (most of the Midwest qualifies, though tick density varies a lot county to county). And the dose has to start within 72 hours of removal.
If you check those boxes, a doctor can prescribe a single dose. One pill, done.
If a tick was on you less than 36 hours, or you can’t be sure what kind it was, prophylaxis usually isn’t recommended. The risk of Lyme transmission climbs sharply only after the tick has been feeding for a day and a half.
Days 3 Through 30: Watch and Wait
Tick-borne illnesses move slowly. Most don’t show symptoms in the first three days. They start to surface anywhere from 3 to 30 days after the bite.
Watch the bite site. A small red bump that fades within a week is normal. An expanding red ring (sometimes with a clearer center, the bullseye rash) is not normal and is a classic sign of Lyme. If you see one, contact a doctor that same day.
Also watch for fever, chills, headache, muscle and joint aches, swollen lymph nodes, and unusual fatigue. These can come on without a rash, especially with tick-borne illnesses other than Lyme, such as Rocky Mountain Spotted Fever or ehrlichiosis.

When to Call a Doctor That Same Day
A few situations are worth a check in with a doctor right away. A tick that was attached for more than 36 hours, or one you can’t be sure about. A bite from a tick known to carry Lyme in an area where Lyme is common. A bite on a child, immunocompromised person, or someone pregnant. A spreading red area within hours rather than days. Or any tick bite where you’d feel better having a doctor weigh in.
Where ChatRx Fits
ChatRx treats tick bite prophylaxis as part of our 39 acute conditions. If you’ve recently removed a tick and meet the criteria for preventive antibiotics, our doctors can review your case and send a prescription to your pharmacy. Chat-based, $25 flat. Available in Indiana, Illinois, and Michigan.
For tick bites where symptoms have already developed (suspected Lyme, fever, joint pain), our doctors will steer you toward in-person care, since those situations need lab work and longer treatment courses than virtual care can handle.
The free symptom checker can also help you sort whether what you’re feeling needs urgent attention. No account required.
Quick Take
Found a tick? Get it off with tweezers, wash the area, save the tick, and write down the date. Decide on prophylaxis within 72 hours if the criteria fit. Then watch the bite, and your overall health, for the next 30 days. Most tick bites are uneventful. The ones that aren’t are far easier to treat early than late.
No. Lyme disease requires the tick to be attached and actively feeding. A tick that hasn’t embedded cannot transmit the bacteria. That said, if you found one crawling, check your entire body. Ticks often walk for 30–60 minutes before choosing an attachment site.
Testing immediately after a bite isn’t useful and can be misleading. Lyme antibodies take 2–6 weeks to develop, so a test done in the first few days will almost always come back negative, even if infection occurred. Testing is most reliable and informative when symptoms are already present.
