Side effects of Prozac?
Hello, Doctor: I would like to inquire about the medication Wellbutrin (Bupropion).
What are its side effects, and how toxic is it? Are there any special contraindications or long-term effects? I have been taking Wellbutrin for eight years, from 1995 until now, consistently one tablet a day.
Earlier this year, I experienced a period of significant depression, and my doctor advised me to increase my dosage to two tablets daily, which I have continued.
I am not particularly afraid of its toxicity or side effects; I just want to know more about this medication that has accompanied me for many years.
Thank you for your guidance, and I wish you joy.

Dear friend: You inquired about the side effects of long-term use of Prozac (fluoxetine).
After reviewing some literature, I have summarized the findings as follows:
Gastrointestinal side effects (more common, occurring in up to 20% of patients): nausea, decreased appetite, and diarrhea.
Central nervous system side effects (less common, approximately 3-5%): increased agitation, insomnia, and tremors.
Other rarer side effects include: the emergence of intense suicidal thoughts (generally occurring early in treatment), and sexual dysfunction (such as anorgasmia or delayed ejaculation).
Additionally, a small number of patients may experience allergic reactions (typically occurring early in treatment).
I recommend discussing this further with your treating physician.
Wishing you peace and joy!

More Info
Wellbutrin, known generically as bupropion, is an atypical antidepressant primarily used to treat major depressive disorder and seasonal affective disorder. It is also prescribed to help individuals quit smoking. Understanding its side effects, risks, and contraindications is crucial, especially for long-term users like yourself.
Common Side Effects of Wellbutrin
1. Insomnia: Many patients report difficulty sleeping when taking Wellbutrin, particularly if taken later in the day. Adjusting the timing of the dose can sometimes alleviate this issue.
2. Dry Mouth: This is a frequent complaint among users and can be managed by staying hydrated or using saliva substitutes.
3. Nausea and Vomiting: Some individuals may experience gastrointestinal upset, particularly when starting the medication or increasing the dosage.
4. Increased Sweating: This side effect can be bothersome but is generally not harmful.
5. Anxiety or Agitation: While Wellbutrin can help alleviate depressive symptoms, it may also increase anxiety in some individuals, particularly at higher doses.
6. Dizziness: Some users report feeling lightheaded or dizzy, especially when standing up quickly.
7. Weight Changes: Unlike many other antidepressants, Wellbutrin is less likely to cause weight gain and may even lead to weight loss in some individuals.
Serious Risks and Considerations
1. Seizures: One of the most significant risks associated with Wellbutrin is the potential for seizures, particularly at higher doses (above 450 mg per day) or in individuals with a history of seizures or eating disorders. It is crucial to adhere to prescribed dosages and consult your physician if you have any concerns.
2. Mood Changes: While Wellbutrin can improve mood, it may also lead to increased irritability or mood swings in some patients. Monitoring your mood and discussing any changes with your healthcare provider is essential.
3. Allergic Reactions: Though rare, some individuals may experience severe allergic reactions, including rash, itching, or swelling. If you notice any unusual symptoms, seek medical attention immediately.
4. Interactions with Other Medications: Wellbutrin can interact with various medications, including other antidepressants, antipsychotics, and medications that lower the seizure threshold. Always inform your doctor about all medications and supplements you are taking.
Special Precautions
- Pregnancy and Breastfeeding: Wellbutrin is classified as a Category B drug, indicating that it is generally considered safe during pregnancy. However, it is essential to discuss any potential risks with your healthcare provider if you are pregnant or planning to become pregnant.
- History of Substance Abuse: Individuals with a history of substance abuse may be at higher risk for misuse of Wellbutrin. Close monitoring by a healthcare provider is recommended.
- Pre-existing Conditions: If you have a history of eating disorders, seizure disorders, or bipolar disorder, it is crucial to discuss these with your doctor before starting or continuing Wellbutrin.
Conclusion
Wellbutrin can be an effective treatment for depression and smoking cessation, but like any medication, it comes with potential side effects and risks. Given your long-term use of Wellbutrin, it is commendable that you are seeking to understand more about the medication. Regular follow-ups with your healthcare provider are essential to monitor your response to the medication and make any necessary adjustments. If you experience any concerning symptoms or side effects, do not hesitate to reach out to your doctor for guidance. Your health and well-being are paramount, and open communication with your healthcare team is key to successful treatment.
