Missed A TRT Injection? What To Do Next
Testosterone replacement therapy (TRT) in Canada is a common and effective treatment for men managing low testosterone levels.
When taken consistently, TRT can help restore energy, mood, muscle mass, libido, and overall well-being.
But what happens if you miss a scheduled injection? It's a question many men face, and it can cause understandable concern about potential side effects or disruptions in progress.
If you're undergoing TRT in Canada and have missed a dose, don't panic—and don't double up on your next injection. Doing so can lead to unwanted hormone fluctuations.
Instead, read on for expert-backed steps on how to handle a missed dose, what symptoms to watch for, and how to stay on track moving forward. Always consult your healthcare provider for personalized advice, especially if you're unsure how to adjust your schedule.

First Steps if You Miss a Dose
Missing a testosterone injection can be stressful, but the first and most important step is to stay calm. One missed dose is unlikely to cause major setbacks or long-term issues, especially if your overall schedule has been consistent. The key is how you respond.
As a general rule, if you remember your missed TRT injection within a few hours of the scheduled time, go ahead and take the dose. However, if you realize it much later—or it's already close to the time of your next scheduled shot—it's best to skip the missed dose entirely. Doubling up can lead to an unnatural spike in testosterone levels, which may cause side effects or disrupt your hormone balance.
When in doubt, contact your healthcare provider. They can advise you on the safest course of action and help determine whether your dosing schedule needs to be adjusted.
In Canada, clinics that offer testosterone replacement therapy are accustomed to these situations and can offer clear, individualized guidance.
Why You Shouldn't Double the Dose
When it comes to testosterone replacement therapy (TRT), maintaining hormonal balance is key. If you miss an injection, it may be tempting to "catch up" by taking a double dose—but this is strongly discouraged by medical experts. Doubling your testosterone dose can lead to a sudden spike in hormone levels, increasing the risk of side effects such as:
- Mood swings or irritability
- Headaches or pressure-like sensations
- Fluid retention or bloating
- Sleep disturbances
Clinical guidelines, including those provided by manufacturers like Pfizer (for Depo-Testosterone) and various TRT clinics across Canada, advise patients to never double up on their next injection. Doing so can destabilize your treatment and counteract the benefits of steady, controlled hormone replacement.
TRT is most effective when delivered in consistent, measured doses. The goal is to mimic your body's natural hormone rhythms—not override them. If a dose is missed, focus on resuming your regular schedule and contacting your healthcare provider if you're unsure how to proceed. Overcorrection can cause more harm than the missed dose itself.
What Happens When You Miss a Dose
Missing a single testosterone injection typically won't derail your progress, but you might notice temporary changes depending on how long it's been since your last dose. Because TRT works by maintaining stable hormone levels, even a brief lapse can cause a dip in testosterone that leads to short-term symptoms such as:
- Fatigue or low energy
- Decreased libido or sexual performance
- Mood shifts, irritability, or mild depression
- Trouble focusing or a return of brain fog
For most men, these symptoms are mild and short-lived after one missed dose. However, repeatedly missing injections can cause testosterone levels to drop below therapeutic range, which may reverse the benefits of your treatment and lead to a full return of low T symptoms over time.
If you're starting to feel these effects after a missed dose—especially if it's been more than a few days—it's a good idea to reach out to your provider. In Canada, many clinics offering testosterone replacement therapy can help you assess whether your levels are dipping and provide support to get back on track.
Practical Tips to Stay on Schedule
Consistency is key with testosterone replacement therapy, and the best way to avoid missed injections is to build a routine that works for your lifestyle. Here are some simple, effective strategies to help you stay on track:
- Set phone reminders or use a TRT tracking app to alert you when it's time for your injection. Visual prompts and recurring alarms can make a big difference.
- Keep your supplies well-stocked. Running out of medication is one of the most common reasons men miss a dose. Order refills early to avoid gaps.
- Pick a consistent day and time each week for your injection. Whether it's Sunday morning or Wednesday night, building the habit around a routine makes it easier to remember.
- Consider pharmacy auto-refill or clinic reminders, especially if you're receiving your medication through a testosterone clinic in Canada. Some providers offer automatic shipments or digital alerts to keep your treatment on schedule.
By planning ahead and building structure into your treatment, you can minimize missed doses and maintain the steady hormone levels needed for effective TRT.
What Canadian Guidelines Say
In Canada, testosterone replacement therapy is guided by evidence-based recommendations from organizations like the Canadian Urological Association (CUA), as well as Health Canada–approved medication guidelines. While there's no universal national protocol specifically for missed doses, the general approach aligns with international best practices: maintain consistent dosing and do not double up after a missed injection.
For example, the product monograph for Depo-Testosterone—a commonly prescribed injectable testosterone in Canada and distributed by Pfizer—advises that if a dose is missed, it should be taken as soon as possible, unless it's close to the next scheduled dose. In that case, the missed dose should be skipped entirely to avoid accidental overdose or hormonal imbalances.
Canadian TRT clinics and pharmacies typically follow these same principles and may offer additional tools like appointment reminders, dose-tracking systems, and auto-refill services to support patient adherence. If you're unsure how to proceed after missing a dose, your Canadian provider will be your best resource for adjusting your schedule safely and keeping your treatment on track.
When to Call Your Doctor
While missing a single testosterone injection might not require immediate medical attention, there are certain situations where it's best to reach out to your healthcare provider. Being proactive ensures your treatment remains safe, effective, and tailored to your needs.
You should contact your doctor if:
- Your symptoms return strongly, such as severe fatigue, low libido, or mood swings, even after resuming your injections.
- You miss more than one dose, especially within a short period of time, which may require a temporary schedule adjustment.
- You're unsure how to safely get back on track, or have questions about timing, side effects, or your overall treatment plan.
In Canada, most clinics offering testosterone replacement therapy are accustomed to helping patients navigate missed doses and can provide guidance quickly—often through virtual appointments or secure messaging. Don't wait for symptoms to worsen; a short check-in can help prevent bigger disruptions to your hormonal balance.
Conclusion: Stay Steady, Stay Supported
Missing a testosterone injection can be unsettling, but it doesn't have to throw your entire treatment off course. The key is to stay calm, avoid doubling your dose, and return to your regular schedule or consult your provider if you're unsure.
Whether you're managing TRT on your own or through a clinic in Canada, consistency and communication are essential. One missed dose won't undo your progress—but staying informed and proactive will keep your therapy safe and effective in the long run.
When in doubt, reach out to your healthcare provider for personalized guidance—and use simple tools like reminders and routine planning to stay on track with your testosterone replacement therapy.
