Does Paxil cause headaches? (5+ factors)

In this article, we will discuss whether Paxil causes headaches. Furthermore, we will discuss what the research suggests, potential causes, do headaches with Paxil improve over time and management strategies for Paxil-induced headaches. 

Does Paxil cause headaches?

Paxil may cause headaches and it is a common side effect. Patients taking Paxil may experience headaches during the initial phase of treatment and this side effect may subside as the body adjusts to the medicine. 

Paxil belongs to the selective serotonin reuptake inhibitors (SSRIs) and is approved by the FDA to treat major depressive disorder (MDD), obsessive-compulsive disorder (OCD), social anxiety disorder (SAD), and other related mental health conditions. 

Paxil increases serotonin levels by blocking its reuptake in the brain cells and serotonin (a chemical neurotransmitter) regulates sleep, mood, appetite, and the body’s stress response (1). 

What does research suggest about Paxil causing headaches?

Several research studies have suggested that Paxil may cause headaches during the early phase of treatment. Most of the patients may recover from headaches after two to three weeks as their body adjusts (2). 

According to a research study, SSRIs have a slightly increased risk of causing headaches. Researchers also suggest that headaches reported after starting SSRI treatment may be coincidental rather than directly caused by the medication (3). 

Another study indicated that when Paxil or other SSRIs are stopped suddenly, they may cause withdrawal symptoms, such as headaches, drowsiness, nausea, and flu-like symptoms (4). 

What are the potential causes of Paxil-induced headaches?

The following causes may contribute to Paxil-induced headaches: 

• Paxil increases serotonin levels in the brain, which can sometimes lead to headaches in certain individuals.
• Paxil’s impact on serotonin can affect blood vessel function, which might trigger headaches during the early phase of treatment. 
• Some individuals who are sensitive to Paxil might get side effects such as headaches. 
• In some cases, headaches may occur due to stress and anxiety for which Paxil is prescribed. 
• Your doctor may adjust the dosage if you are taking a higher dose of Paxil due to which you may experience headaches. 
• Sudden discontinuation of Paxil may also result in side effects such as headaches (4,5,6).  

Do Paxil-induced headaches improve over time?

Paxil-induced headaches may improve over time for most of the individuals. Headaches are most commonly observed in the initial phase of antidepressant treatment. 

However, these headaches may subside as the body adapts to the medication or when Paxil start showing its therapeutic benefits after a few days or weeks, but some people may experience headaches throughout while taking Paxil. SSRIs such as Lexapro, Celexa, and Zoloft are commonly associated with headaches.  

How to differentiate between Paxil-induced or other types of headaches? 

To differentiate between Paxil-induced and other types of headaches, some characteristics might be considered, including: 

Onset and duration 

Paxil-induced headaches may occur in the early phase of treatment or when the dose is adjusted. Your body may take some time to adjust to Paxil and it may subside in a few days. However, some individuals may experience it throughout Paxil treatment. 

Random headaches may occur due to several reasons including lack of sleep, hunger, bright lights, strong odour, stress or other factors. Such headaches may subside by taking OTC painkillers or getting some rest. 

Frequency

Paxil-induced headaches may occur consistently when the medication is started or the dose is adjusted. Other types of headaches may occur frequently or for a short duration, and vary in intensity from person to person. 

Nature of pain 

Paxil-induced headaches may be felt as pressure-like sensations and they are not localized to any particular area of the head. Random headaches are usually one-sided such as in migraines, or may be felt in the forehead region when they are associated with stress. These headaches may be severe or mild depending on the individual sensitivity. 

Other symptoms

Paxil-induced headaches may also be accompanied by other symptoms such as nausea, abdominal discomfort, dizziness, or others. Random headaches may have other symptoms such as visual disturbances, or tiredness. 

Treatment 

Paxil-induced headaches may not get better with OTC painkillers; however, other types of headaches such as tension or migraines may be treated with OTC pain relievers including, ibuprofen, or acetaminophen.

How to get rid of headaches while taking Paxil?

You may get rid of Paxil-induced headaches in the following ways: 

• You may use over-the-counter painkillers such as Paracetamol, Acetaminophen, and Ibuprofen to relieve the headaches. 
• If you are taking a higher dose, your doctor may adjust the dose and monitor your response. 
• Drink plenty of water throughout the day which may prevent worsening of headaches. 
• Ensure enough sleep of 8-9 hours per day. 
• Reduce or avoid screen time as it may put pressure on your eyes and may increase the intensity of headaches. 
• Maintain an active lifestyle and be involved in some kind of physical activity, such as walking, yoga, or aerobics. 
• Massage your forehead with oils, such as Lavender, or Rosemary oils. These oils may improve your blood circulation which helps to prevent the worsening of headaches. 

In my opinion, headache is a common side effect of Paxil experienced by most of the individuals. However, it is mostly observed in the early phase of treatment and generally subsides as the body adjusts to the medication. In case your headaches worsen or persist while taking Paxil, please reach out to your healthcare provider.
