Buspirone is a medication used to treat Generalized Anxiety Disorder (GAD). It impacts multiple different chemical signals in the brain, called neurotransmitters, to reduce anxiety. Buspirone also goes by the brand-name Buspar. It is often popular because it has fewer side effects than many other anti-anxiety medications.

One thing that can be frustrating for someone just starting out is the buspirone timeline. Buspirone can take several weeks to create noticeable change in anxiety symptoms. This sometimes leaves people worrying that their Buspar is not working. It’s important to know that a lag time of several weeks can be normal.

Why Buspirone Doesn't Work Right Away

Buspirone works by changing the serotonin signalling pathways in your brain. Serotonin is a neurotransmitter that is involved in mood regulation. It reduces anxiety and increases feelings of well-being. Buspirone binds to the serotonin receptors in your brain. Scientists believe that this over time changes how the circuits function. This process of change can take several weeks.

Buspirone Timeline: Week by Week

If you’re starting buspirone, the process of waiting to see if it will work for you may be anxiety-inducing. It can help to know what the usual buspirone timeline is. Buspirone’s onset of action can be broken down into 3 stages.

Weeks 1-2: Minimal Change

The first stage is weeks 1-2. During this time, most patients do not notice any difference. This doesn’t automatically mean that your Buspar is not working. The process of changing brain signalling happens gradually. It’s important to take the medication consistently as prescribed even if you’re not necessarily seeing a difference. Your provider may have you increase the dose every few days as long as you’re not experiencing side effects.

Weeks 2-4: Gradual Improvement

The second stage is weeks 2-4. During this time, people often start to notice gradual improvement. The change occurs slowly, so it may not be noticeable from day to day. However, if you compare how you feel in week 3 or 4 on buspirone vs how you felt in week 1 or before starting the medication, the improvement might be more easily noticeable. People may notice fewer physical symptoms of anxiety, or simply a general sense of being more at ease. 

Weeks 4-6 and Beyond: Full Effect

The third stage of the buspirone timeline is weeks 4-6 and beyond. This is when the benefits of buspirone are reported to reach a steady state. Your provider may still advise dose adjustments during this time if needed. In order to ensure the medication continues to be effective, it’s important to remain consistent with dosing. If you’re noticing any decrease in the efficacy of your Buspar, let your provider know so they can help navigate any needed changes.

Why Buspirone Feels Like It's Not Working

People may worry that Buspar is not working because there isn’t a noticeable change right after taking it. But buspirone is not designed to create instant relief from anxiety. Benzodiazepine medications like Xanax (alprazolam) or Klonopin (clonazepam) can be felt within minutes of taking a dose. That is what makes them effective to stop an active panic attack.  Buspar works differently. It is not a sedative, which is part of why it is safer than benzodiazepines and not addictive. Several placebo-controlled trials have compared buspirone against benzodiazepines, and found that buspirone works better than placebo and equally as well as benzodiazepines over a 4 week period.

What to Do If Buspirone Isn’t Helping After 6 Weeks

If Buspar isn’t helping with anxiety after 6 weeks let your provider know that the medication hasn’t helped. There are several paths forward, and selecting the right one for you is a shared decision with your provider! 

It may be that the dose simply isn’t high enough. Your provider may recommend increasing the dose. The typical maximum dose of Buspar is 60 mg per day, split up across two or three doses. Studies have shown no significant difference between twice vs three times daily dosing. Your provider may also recommend adding a second medication for additional benefit. Non-medication changes like exercise, time outdoors, or therapy can also be helpful for combating anxiety. 

While you’re taking Buspar, it’s important to remain consistent. Missed doses can have a significant impact on the medication’s effectiveness. Buspar can be taken with or without food, but it should be taken the same way every time. If you’re finding it challenging to remember to take medication multiple times daily, you’re not alone. Many people find it helpful to set an alarm or calendar reminder, use a visual cue like a sticky note, or use a pill container placed in a clearly visible location like on the bathroom counter.

Keep your provider updated on any new supplements or medications you’re taking, as they may reduce the efficacy of Buspar. Do not stop taking your medication without talking to your doctor. Even if you’re not sure buspirone is helping, stopping suddenly can lead to rebounding anxiety symptoms.

Can You Take Buspirone With Other Anxiety Medications?

Buspirone can be safely combined with some other anxiety medications, but not all. If you’re wondering about the safety of buspirone with other medications you’re taking, speak to your healthcare provider about your questions. It’s important to make sure your provider is aware of all medications and supplements you take.

One study looked at combining Buspar with SSRIs, which are medications like Prozac (fluoxetine), Celexa (citalopram), and Zoloft (sertraline). SSRIs can be used for both depression and anxiety.  The researchers included 119 patients in the study. While they did not see a clear benefit to adding Buspar to an SSRI, they also found no significant difference in the rate of adverse events.  They concluded that adding Buspar to an SSRI is safe and well tolerated

Another type of medication used for anxiety and depression is called MAOIs. Some MAOIs can also be used for Parkinson’s Disease. Examples of MAOIs include Emsam/Zelapar (selegiline) and Nardil (phenelzine). These medications cannot be safely taken with Buspar. Doctors recommend a 14 day waiting period off of either medication when switching between Buspar and an MAOI. This is to avoid the risk of something called serotonin syndrome, which can be very dangerous.

FAQs

When does buspirone kick in?

It can take 2-4 weeks to notice the benefits of buspirone. The change happens gradually as your brain adjusts. By the 4-6 week mark, full benefit is usually achieved for the dosing level.

Can you feel buspirone the first day?

Because buspirone takes a couple of weeks to build up in your system and take effect, you likely won’t feel anything the first day. This doesn’t mean the medication won’t work! Continue to take it as prescribed, and keep your provider updated on any questions or concerns.

When should you increase the dose of buspirone?

Your provider will help guide you through the initial dose adjustment process. It’s common to increase the dose every couple of days early in treatment to reach a standard level. If you’re not noticing benefits, or seeing only a little improvement, let your provider know! 

Can you take buspirone as needed?

Buspirone is not approved for as-needed use. Reaching a consistent level of effectiveness requires several weeks of regular dosing, usually two or three times daily.  If you’re struggling to stick to the frequent dosing required, talk to your healthcare provider about strategies that may be helpful, and if a different medication may be right for you.

What are the common side effects of Buspar?

The most common side effect of buspirone is dizziness, which occurs in just over 10% of patients. Drowsiness occurs in approximately 10% of patients. With dose changes, people may experience headache or nausea. 

Is buspirone addictive?

No, buspirone is not addictive. The brain pathways that buspirone works on are different from those of benzodiazepines like Xanax, which can be addictive.

Does buspirone cause weight gain?

Buspirone is considered weight-neutral, meaning it is not typically associated with weight gain. This sets it apart from some other anxiety medications, including certain SSRIs and benzodiazepines, which may contribute to weight changes. If you're concerned about how your medication might affect your weight, talk to your provider about options.

Is buspirone an SSRI?

No. Buspirone is an anxiolytic that works on serotonin receptors differently than SSRIs. It belongs to a class of medications called azapirones. Buspirone is sometimes prescribed alongside an SSRI, but it is a separate type of medication with a different mechanism of action.
