Comparing Cymbalta vs Pristiq

Cymbalta and Pristiq both used to manage depression and anxiety but work differently. Cymbalta can also manage chronic pain because it balances the levels of serotonin and norepinephrine in the brain. This makes it useful for people dealing with both pain and mental health conditions.

Pristiq’s targeted effect on brain chemicals might be better for those wanting to improve their mood. According to some studies, it could also improve thinking. It’s important to note that Pristiq can lead to dry mouth, fatigue, and sleep disturbances, while Cymbalta may cause stomach issues, dizziness, and changes in vision. 

Choosing between these medications requires an understanding of the medications’ pharmacological profiles and your medical history, best discussed with your provider. For instance, Cymbalta’s broader side effects, including gastrointestinal issues, may be a deciding factor for you. Conversely, Pristiq’s potential for less frequent side effects could better align with your needs.

SNRIs are a large class of medications that work by blocking the reuptake of serotonin and norepinephrine, increasing the levels of these 2 neurotransmitters in the brain.

Serotonin and norepinephrine are 2 important neurotransmitters that are involved in numerous important bodily functions, including mood and energy levels.

SNRIs can treat symptoms of anxiety and depression

Serotonin and SNRIs are considered the first-line treatment for anxiety and depression. This class of medications is highly effective and considered to be relatively safe, with minimal serious adverse effects. 

Anxiety and depression are 2 of the most commonly diagnosed mental health conditions and often coexist with one another. Below, we have listed some of the most common symptoms associated with both anxiety and depression. 

Symptoms of depression: 

• Persistent feelings of sadness, helplessness, or hopelessness 
• Loss of interest in pleasurable activities or hobbies

• Changes in appetite
• Difficulty concentrating 
• Severe depression can be associated with thoughts of self-harm or suicidal ideation

• Sleep disturbances 
• Fatigue 
• Difficulty concentrating

SNRI warnings 

Before starting an SNRI medication, there are a few cautions that should be considered. 

Boxed warning 

Most antidepressant medications include a boxed warning, which is the strongest warning issued by the FDA, alerting you and healthcare providers to serious risks associated with the medication. This warning typically highlights the potential risk of worsening anxiety and depression, which may lead to thoughts of self-harm or suicidal ideation.

Of note, this is a rare adverse effect associated with SNRI medications and has only been found in a small number of patients. This was most commonly found in teenagers and young adults under the age of 24. 

Increased risk of bleeding 

SNRIs are associated with an increased risk of bleeding. Always tell your provider about any medications you currently take, including all over-the-counter medications and supplements. 

You should avoid all blood-thinning medications, such as aspirin and warfarin. NSAIDs should also be avoided, as they can increase the risk of bleeding. 

Signs and symptoms of bleeding include: 

• Blood in urine or stool 
• Black or tarry stools 
• Severe or persistent abdominal pain 
• Easy bruising 
• Bleeding gums with teeth brushing 

Serotonin syndrome

Serotonin syndrome is a rare but serious condition that is caused by increased levels of serotonin in the body. This most commonly occurs when someone is taking more than one medication that increases the level of serotonin. 

If you begin to experience any of the following symptoms, contact your health provider or seek immediate medical attention: 

• Increased heartbeat 
• High blood pressure
• Restlessness 
• Nausea, vomiting, diarrhea 
• Increased body temperature and sweating 
• Tremor 
• Loss of coordination or balance 
• Muscle spasms 

Discontinuation or withdrawal syndrome 

It’s important not to abruptly discontinue your medication, as this can result in withdrawal syndrome. Symptoms of withdrawal include headache, nausea, diarrhea, dizziness, and insomnia. If you’re unhappy with your SNRI medication, inform your healthcare provider, and they’llsafely taper you off of your medication. 

Caution with use in the elderly population 

SNRI medications should be used with caution in those over 65. This is because of an increased risk of adverse effects in the elderly population and can result in dangerous changes in blood pressure or low sodium levels in the blood, which can result in injury from falls.
