Wellbutrin XL is the brand name for bupropion hydrochloride extended-release, a prescription medicine used to treat major depressive disorder and to help prevent seasonal episodes of depression. It is taken once a day, and the extended-release formulation is designed to release the medicine gradually.
Forgetting one dose of Wellbutrin XL does not necessarily cause noticeable symptoms. Some people may feel no different at all. Others may notice changes in mood, energy, concentration, or other symptoms, particularly if they are sensitive to changes in their medication routine.
The important point is that a missed dose should not be replaced with an extra dose. The official medication information says to skip the missed dose and take the next dose at the regular time because taking too much bupropion can increase the risk of seizures.
Key Takeaways
- Missing one Wellbutrin XL dose may not cause noticeable symptoms, but some people may notice changes in mood, energy, focus, or sleep.
- Do not take two doses together to make up for a missed dose because taking too much bupropion can increase the risk of seizures.
- If you miss several doses, contact your doctor or pharmacist for advice instead of changing your dose yourself.
- Taking Wellbutrin XL consistently as prescribed can help keep your treatment routine on track.
- Seek immediate medical help for a seizure, suicidal thoughts, severe confusion, or other serious or unusual symptoms.
What Happens If You Miss a Dose of Wellbutrin XL?
Wellbutrin XL is designed to maintain bupropion levels in the body between doses. When you miss a dose, the amount of medicine in your body will gradually decrease.
One missed dose may not produce any obvious change. However, depending on the person and how long they have been taking Wellbutrin XL, some people may notice that certain symptoms return or become more noticeable.
Possible effects can include:
- Changes in mood
- Lower energy
- Difficulty concentrating
- Irritability
- Anxiety
- Changes in sleep
- Return of depressive symptoms
These symptoms are not guaranteed to happen after missing a dose. They can also have other causes, such as stress, poor sleep, illness, or changes in daily routine.
Can Missing One Dose of Wellbutrin XL Cause Withdrawal Symptoms?
Missing one dose of Wellbutrin XL does not necessarily cause withdrawal symptoms.
Bupropion is different from some antidepressants that are particularly associated with discontinuation symptoms. However, people can respond differently when they miss medication.
You might notice that you feel different after missing a dose, but that does not automatically mean you are experiencing withdrawal.
If you have missed several doses or stopped taking Wellbutrin XL suddenly, speak with your healthcare provider. The prescribing information advises patients not to change their dose or stop treatment without discussing it with their healthcare provider.
Mood Changes After Missing Wellbutrin XL
Wellbutrin XL is used to treat major depressive disorder, so maintaining a consistent treatment schedule is important.
After missing a dose, some people may notice changes in their mood. They might feel more down, less motivated, or more irritable than usual.
However, one missed dose does not mean that depression will immediately return.
Antidepressants generally work over time, and the effects of missing a single dose can vary from person to person. If you repeatedly forget doses, however, maintaining a consistent medication routine can become more difficult.
If your mood changes significantly after missing doses, talk with your healthcare provider.
Can Missing a Wellbutrin XL Dose Make You Feel Tired?
It is possible to notice lower energy after missing a dose, although tiredness is not an inevitable result of missing Wellbutrin XL.
Some people taking bupropion may feel that the medicine helps with energy, motivation, or concentration as part of their overall improvement in depression. If the medication is interrupted, they may notice changes in these areas.
At the same time, tiredness can result from many other things, including lack of sleep, stress, illness, and other medications.
If fatigue becomes persistent or severe, it is worth discussing with a healthcare professional.
Can Missing Wellbutrin XL Affect Concentration?
Some people may notice changes in concentration or motivation after missing a dose.
Because Wellbutrin XL is prescribed for depression, maintaining the treatment schedule may help keep symptoms under control. If depressive symptoms begin to return, difficulty focusing may be one of the things a person notices.
However, one missed dose does not automatically cause concentration problems.
If you frequently miss doses because of a busy schedule or forgetfulness, consider talking with your pharmacist or healthcare provider about ways to make your medication routine easier to follow.
Can Anxiety or Irritability Occur?
Changes in mood, anxiety, or irritability may occur when someone’s underlying symptoms become more noticeable after missing medication.
It is important not to assume that every feeling of anxiety or irritability is caused by the missed Wellbutrin XL dose. These symptoms can have many causes.
The official medication information lists agitation and anxiety among possible adverse reactions to Wellbutrin XL itself.
If you experience significant anxiety, agitation, or unusual changes in behavior, contact your healthcare provider.
What Should You Do If You Miss a Dose of Wellbutrin XL?
The instructions for Wellbutrin XL are straightforward: do not take an extra tablet to make up for the missed dose.
Instead, wait and take your next dose at the regular time. The medication guide specifically warns that taking too much Wellbutrin XL can increase the risk of having a seizure.
Do not take two tablets together unless your healthcare professional has specifically instructed you to do so.
It is also important to keep doses at least 24 hours apart.
Why Should You Not Double the Dose of Wellbutrin XL?
Bupropion has a dose-related risk of seizures. Taking more than prescribed can increase that risk.
This is why the official instructions specifically say not to take an extra dose after forgetting one.
This is particularly important with an extended-release medication. Wellbutrin XL tablets should be swallowed whole and should not be crushed, cut, or chewed because doing so can alter how the medicine is released.
If you accidentally take more Wellbutrin XL than prescribed, contact a healthcare professional, poison control center, or emergency service for guidance rather than waiting for symptoms.
What If You Miss More Than One Dose of Wellbutrin XL?
Missing several doses is different from forgetting one dose.
If you have missed multiple doses, do not try to make up for them by taking several tablets at once. The official medication guide recommends returning to the regular dosing schedule rather than taking extra medication.
If you have stopped taking Wellbutrin XL for several days, contact your prescribing healthcare professional for advice about restarting it.
This is especially important if you have experienced changes in mood or other symptoms during the interruption.
Can Missing a Wellbutrin XL Dose Cause Depression to Return?
Missing one dose does not necessarily cause depression to return immediately.
However, Wellbutrin XL is intended to be taken consistently as prescribed. Repeatedly missing doses can interfere with the treatment plan and may make it harder to maintain improvement.
If you notice worsening sadness, loss of interest, changes in sleep or appetite, hopelessness, or other symptoms of depression, contact your healthcare provider.
People taking antidepressants should also be aware of serious mood changes. The medication guide contains a warning about suicidal thoughts and behaviors associated with antidepressant treatment, particularly in children, adolescents, and young adults.
If you have thoughts of suicide or feel that you may hurt yourself, seek emergency help immediately or contact a crisis service in your area.
How Long Does Wellbutrin XL Stay in Your System?
Wellbutrin XL is an extended-release form of bupropion. The medicine is released over time rather than all at once.
Bupropion is also metabolized into active metabolites that remain in the body longer than the parent drug. Because of this, missing one dose does not mean that the medicine suddenly disappears from your system.
The exact amount of medicine and its metabolites in your body varies between individuals.
Factors such as metabolism, other medications, liver function, kidney function, and the prescribed dose can affect how the medicine is processed.
How Can You Avoid Missing a Wellbutrin XL Dose?
Taking Wellbutrin XL at the same time each day can make it easier to remember.
The medication guide recommends taking Wellbutrin XL at the same time each day and taking it in the morning.
Some simple reminders may also help:
- Set a daily phone reminder.
- Keep the medication in an appropriate place where you will see it.
- Use a pill organizer if recommended for your medication routine.
- Link your medication with an established morning routine.
- Keep track of your doses.
Do not change the timing or amount of your medication without talking with your healthcare provider.
When Should You Contact a Doctor?
Contact your healthcare provider if you frequently miss doses, have stopped taking Wellbutrin XL, or are unsure about when to restart after missing multiple doses.
You should also seek medical attention for serious or unusual symptoms.
A seizure is a medical emergency. Other concerning symptoms can include severe confusion, unusual behavior changes, significant agitation, or thoughts of suicide.
Wellbutrin XL can also increase blood pressure, and the prescribing information recommends monitoring blood pressure before starting treatment and periodically during treatment.
