A steroid shot in the buttocks typically provides relief for 3 to 6 months, though the exact duration depends on the type of steroid used, the condition being treated, and how your body responds. Some people experience relief for up to a year, while others find the effects wearing off sooner.
When the Shot Starts Working
You probably won’t feel better the same day. It can take up to a week for a steroid injection to reach full effect, so don’t assume the shot didn’t work if you’re still dealing with pain or inflammation for the first few days. Some people notice gradual improvement starting around day two or three, but a full week is a reasonable expectation before judging the results.
How Long Relief Typically Lasts
For most people, a steroid shot that works well provides 3 to 6 months of symptom relief. The specific steroid your provider chooses plays a role in this timeline. Two of the most common options have noticeably different durations of action in the body: triamcinolone (often sold as Kenalog) stays active for about 14 days, while methylprednisolone (Depo-Medrol) lasts roughly 8 days. That difference in how long the drug itself remains active influences how long you feel the anti-inflammatory benefit downstream.
If you’re getting the shot for bursitis, particularly trochanteric (hip) bursitis, the relief window can be wider. Bursa injections reduce pain and inflammation for several months and sometimes up to a full year. For systemic conditions like severe allergic reactions or poison ivy, the shot tends to work on a shorter timeline since it’s managing an acute flare rather than calming a localized joint problem.
When a steroid shot wears off faster than expected, say within a few weeks, that’s often a sign that something else is going on. Your provider may want to investigate other underlying issues or consider different treatment approaches.
What Affects How Long It Lasts
Several factors influence your individual timeline:
- The condition being treated. Inflammatory joint or bursa problems tend to respond longer than acute allergic reactions or skin conditions.
- Severity of inflammation. Mild to moderate inflammation often responds better and longer than severe, chronic inflammation.
- Which steroid is used. Longer-acting formulations provide a more sustained effect than shorter-acting ones.
- Your activity level. Repeated stress on an inflamed area can shorten how long relief holds.
- Whether it’s your first injection. Some people find that repeat injections become less effective over time.
How Often You Can Get One
Most providers recommend no more than three steroid shots per year in any single joint, and no more than six injections total across all sites in a year. Shots should be spaced at least 12 weeks apart. These limits exist because repeated steroid injections can weaken tendons, thin cartilage, and suppress your body’s natural cortisol production if given too frequently.
If you find yourself needing injections more often than every few months, that’s a conversation worth having with your provider about longer-term management strategies rather than continuing to rely on repeat shots.
Side Effects at the Injection Site
The buttocks is one of the safer injection sites because the muscle is deep and well-padded, which reduces the risk of visible skin changes. Still, soft tissue thinning and skin discoloration can occur after any steroid injection, particularly when the medication is deposited too close to the surface. The estimated risk is less than 1%.
Providers often apply pressure with gauze over the injection site as the needle is withdrawn. This helps prevent the steroid from tracking back along the needle path toward the skin surface, which is one of the main causes of localized dimpling or color changes. You may also notice soreness or a dull ache at the injection site for a day or two, which is normal and resolves on its own.
What to Expect After the Shot
The first 24 to 48 hours can feel underwhelming. Some people experience a temporary increase in pain at the injection site, sometimes called a “steroid flare,” before things improve. Over the course of the first week, inflammation gradually decreases and you should start to notice meaningful relief.
Most providers suggest taking it easy for a day or two after the injection but don’t require extended rest. You can typically return to normal activities within a day, though avoiding intense exercise for 48 hours is a common recommendation. If you haven’t noticed any improvement after 10 to 14 days, contact your provider, as the shot may not be addressing the root cause of your symptoms.
