Among these, Strattera (generic name: Atomoxetine) stands out as a non-stimulant medication that is recognized for its effectiveness in managing ADHD symptoms like inattention or impulsivity. 

However, a noteworthy side effect of this popular ADHD medication that has gained attention in recent years is its potential impact on your body and how you may lose weight. It’s important to emphasize that you should always be mindful not to abuse prescription medication as a means for achieving their side effects such as unhealthy weight loss.

In this article, we’ll delve into the relationship between Strattera and weight loss, exploring how this medication can influence one’s body mass while treating ADHD. Don’t wait, get treatment for your ADHD symptoms through the licensed medical providers of Klarity today.

Is Weight Loss a Side Effect of Strattera?

While weight loss is not the primary purpose of Strattera, some individuals have reported experiencing weight changes while taking this medication to treat their ADHD, similar to Strattera’s stimulant counterpart Focalin. It’s important to note that the relationship between Strattera and weight loss is complex and can vary from person to person. Here are some key factors to consider:

  • Appetite Suppression: One of the mechanisms through which Strattera may contribute to weight loss is by suppressing appetite. Some users have reported a decreased desire for food while taking the medication, which can lead to reduced calorie intake and, consequently, weight loss.
  • Metabolism Effects: Strattera may have an impact on metabolism. Some studies suggest that it can increase resting metabolic rate, potentially leading to an increase in calorie expenditure. This could contribute to weight loss in certain individuals.
  • Individual Variations: It’s crucial to remember that not everyone who takes Strattera will lose weight. Individual responses to ADHD medications can vary widely, and some individuals may even experience weight gain as a side effect.
  • Dosage and Duration: The dosage of Strattera and the duration of treatment can also impact the likelihood of experiencing weight changes. Higher doses and longer treatment periods may increase the chances of weight fluctuations.
  • Lifestyle Factors: Lifestyle choices such as diet and exercise can interact with the effects of Strattera. Individuals who maintain a healthy diet and exercise regimen may have different experiences with weight while taking the medication compared to those with less active lifestyles.

While Strattera’s primary purpose is to address ADHD symptoms by altering neurotransmitter levels in the brain, it can indeed have effects on body weight in some individuals. However, it’s crucial to recognize that Strattera should not be used as a supplement to cut weight and should be avoided by people with eating disorders due to their appetite suppression. Weight changes while taking Strattera can vary widely among users, and not everyone will experience weight loss as a side effect. 

If you are considering Strattera as a treatment for ADHD and have concerns about its potential impact on your weight, consulting with a healthcare provider is essential. They can provide personalized guidance based on your medical history, specific needs, and treatment goals.

Side Effects of Strattera that Can Cause Weight Loss

Strattera, in some users, can lead to changes in appetite, sleep patterns, dry mouth, nausea, and headaches — side effects that may indirectly contribute to weight loss. It’s important to note that not everyone who takes Strattera will experience these side effects, and individual responses to the medication can vary. Here are several key side effects of Strattera that contribute to how you may lose weight:

Low Appetite

One of the side effects most commonly associated with Strattera and other ADHD medications is a reduced appetite. Some individuals taking the medication may experience a noticeable decrease in their desire for food. This decreased appetite can manifest as a diminished interest in regularly eating meals and snacks. Over time, reduced calorie intake due to a lack of appetite can lead to gradual weight loss.

Sleep Changes

Strattera can also impact sleep patterns in certain users. Changes in sleep, such as difficulty falling asleep or staying asleep, can disrupt one’s daily routine. Sleep disturbances can affect both the timing and quality of meals. For example, individuals experiencing sleep difficulties may skip meals or eat irregularly, which can indirectly contribute to weight loss by altering eating patterns.

Dry Mouth

Dry mouth is another reported side effect of Strattera. The sensation of dryness in the mouth can make eating and drinking less enjoyable. When the mouth feels dry, individuals may be less inclined to consume food and beverages. As a result, a decreased intake of calories may occur, potentially leading to weight loss.

Nausea or Vomiting

In some more severe cases, Strattera may cause nausea or vomiting as a side effect. These gastrointestinal symptoms can be uncomfortable and may discourage individuals from eating regular meals. Persistent nausea or vomiting can interfere with one’s ability to maintain a balanced diet, resulting in a decrease in calorie consumption and potential weight loss.


While not directly related to weight loss, persistent headaches can have an indirect impact on one’s overall well-being and daily activities. Individuals experiencing frequent headaches may find it challenging to focus on eating, engage in physical activities, or maintain regular eating habits. These disruptions to daily routines can indirectly contribute to changes in body weight over time.

Strattera Vs Adderall: Impact on Weight Loss

Understanding the effects of Strattera and Adderall on body weight is essential for individuals with ADHD who are exploring medication options. Both Strattera and Adderall are commonly prescribed to manage ADHD, however they have distinct mechanisms of action that can result in varying impacts on weight.


Strattera is classified as a non-stimulant medication used to treat ADHD. Its primary mode of action involves inhibiting the reuptake of norepinephrine in the brain. This action helps regulate neurotransmitter levels and improve symptoms of ADHD, such as inattention, impulsivity, and hyperactivity.

One of the noteworthy characteristics of Strattera is its potential to cause appetite suppression. Some individuals taking Strattera may experience a reduced desire for food, leading to a decrease in calorie intake. Over time, this decrease in calorie consumption can result in noticeable weight loss.

However, it’s crucial to emphasize that not all Strattera users will experience weight loss. Individual responses to Strattera can vary widely, and some may even experience weight gain as a side effect. The effects on weight largely depend on factors such as dosage, individual metabolism, and overall lifestyle.


Adderall, on the other hand, belongs to the class of medications known as stimulants. It contains a combination of amphetamine salts and dextroamphetamine, which work by increasing the levels of certain neurotransmitters, including dopamine and norepinephrine. Adderall’s stimulant properties result in increased alertness, focus, and energy levels — qualities that can be particularly beneficial for individuals with ADHD.

It’s not uncommon for users of Adderall to experience weight loss effects similar to that of Strattera. Adderall increases your metabolic rate, where your body is burning more calories than usual, making this a common side effect of this ADHD medication as well.

Strattera Weight Loss Prevention

If you are concerned about the potential for weight loss while taking Strattera, there are proactive steps you can take to minimize this effect and maintain your overall well-being:

  1. Monitor Your Eating Habits: Being mindful of your dietary choices is a crucial aspect of weight management while on Strattera. Aim to maintain a balanced and nutritious diet that provides your body with the necessary nutrients. Consider incorporating a variety of food groups, including fruits, vegetables, lean proteins, and whole grains, into your meals. Regular, well-balanced meals can help ensure you meet your calorie and nutritional needs, even if you experience appetite suppression.
  2. Stay Hydrated: Drinking an adequate amount of water is essential while taking Strattera, as it can help alleviate some of the side effects associated with the medication, such as dry mouth and nausea. Staying well-hydrated can also support your overall health and well-being. Aim to drink enough water throughout the day to maintain proper hydration.
  3. Consult Your Healthcare Provider: Perhaps the most crucial step in managing your experience with Strattera is to maintain open communication with your healthcare provider. If you are experiencing significant weight loss or any discomfort while taking Strattera, do not hesitate to reach out to your healthcare provider. They are your primary resource for guidance and support. Your healthcare provider can assess your specific situation, monitor your progress, and make necessary adjustments to your treatment plan if needed.

Is Strattera Right For You?

The decision to use Strattera as a treatment for ADHD is a significant one and should always be made in consultation with a qualified healthcare provider. Your healthcare provider is well-equipped to evaluate your specific needs and determine whether Strattera is an appropriate choice for you. They will take into account your medical history, the severity of your ADHD symptoms, and any concerns you may have regarding weight changes or potential side effects.

It’s essential to engage in an open and informed discussion with your healthcare provider to ensure that the treatment plan aligns with your individual goals and preferences. Your healthcare provider can provide you with comprehensive information about Strattera, its potential benefits, and any potential side effects. Together, you can make an informed decision regarding the most suitable treatment approach for your ADHD management.
