Can Fluvoxamine cause headaches? (3+ tips)

In this article, we will answer the question “Can Fluvoxamine cause headaches?”. We will also discuss the incidence of headaches caused by Fluvoxamine and some tips to manage or reduce the occurrence of Fluvoxamine-induced headaches.

Can Fluvoxamine cause headaches?

Yes, Fluvoxamine can cause headaches, especially at the start of treatment with this medication. Fluvoxamine is an antidepressant belonging to a class of drugs known as selective serotonin reuptake inhibitors (SSRIs). This medication is used in the treatment of obsessive-compulsive disorder (OCD) and many other depressive illnesses (1).

Fluvoxamine therapy can cause many side effects like headaches, nausea, dizziness, insomnia, dry mouth, nervousness, and increased sweating at the start of therapy. Normally these side effects tend to resolve within 1-2 weeks as your body adjusts to the medication.

Antidepressants including Fluvoxamine, can lower blood sodium levels, causing hyponatremia. If blood sodium levels go too low they can cause symptoms like headaches, confusion, fatigue and nausea. This effect is more common in the starting few weeks when antidepressant therapy is initiated. Elderly patients are also at a higher risk of Fluvoxamine-induced headaches.

What is the incidence of headaches caused by Fluvoxamine?

The incidence of Fluvoxamine-induced headaches varies among patients taking therapy. Research studies suggest that it is a commonly occurring side effect. Many patients experience this side effect at the start of treatment.

A study assessing the pharmacokinetics and pharmacodynamics of Fluvoxamine in depressive disorders reported headaches as a side effect of Fluvoxamine therapy in more than 20% of patients receiving this medication (2).

Another research study evaluating the side effect profile of all SSRIs reported the incidence of Fluvoxamine-induced headache to be almost 21% in individuals receiving treatment. This study also associated Fluvoxamine to be related to a higher incidence of gastrointestinal (GI) side effects as a result of therapy (3).

A study analysing the safety profile of Fluvoxamine in 24,624 patients receiving treatment reported headaches to be a frequently occurring side effect with an incidence of 4.7%. Almost 1.1% of patients discontinued Fluvoxamine due to this reason (4).

How to get rid of Fluvoxamine-induced headaches?

You can take OTC painkillers like Paracetamol, Naproxen or Ibuprofen to help you manage Fluvoxamine-induced headaches. Paracetamol is considered the safest option to manage any type of headache, due to its wide safety profile.

Naproxen and Ibuprofen are also good options but because they belong to a class of medications called NSAIDs, they can produce GI side effects in individuals. They may help you relieve your headache, but may also cause unwanted effects on your stomach.

Headaches caused by Fluvoxamine or other antidepressants (like bupropion or escitalopram) can go away on their own when your body gets used to the medication. If your headaches do not subside or get worse, make sure to reach out to your healthcare provider regarding your concerns.

Tips to manage Fluvoxamine-induced headaches

In addition to OTC medications, there are various tips and techniques which can help relieve your headache. Some of them are as follows:

  • Take a break from activities that may worsen your headache and rest in a quiet and dark environment.
  • Try getting some sleep. Sometimes getting too little sleep can also increase your headache.
  • Applying a cold or warm press to the affected area can help reduce some of the symptoms. You can try applying a cold pack or warm towel to your head.
  • Manage your stress by practising relaxation and stress management techniques meditation.
  • Dehydration can cause headaches to worsen so keep yourself well hydrated. Drink plenty of water and fluids.
  • Try drinking tea or coffee but in moderation. Caffeine can increase the effects of OTC painkillers.
  • Avoid triggers like strong odours, loud noises, bright lights and certain foods.
  • Lower your alcohol intake as it can also aggravate your headache.
  • Avoid electronic devices like tablets or mobile phones, because light from these devices can strain your eyes and increase your headache.
  • Try a gentle massage to the temples, base of the skull, neck and shoulders. Using essential oils like peppermint, rosemary and lavender oil can also help.
  • Try to maintain good posture to get rid of any pressure on your neck.
  • Take a healthy diet and maintain a regular exercise routine.
  • Keep a journal and record your headache incidences to identify any possible patterns.

Understanding Fluvoxamine-induced headaches

To summarise, Fluvoxamine can cause headaches. This fact has been well proven by research studies. It is a side effect of the medicine and not everyone experiences it. It can subside on its own after a few days when your body adjusts to the medication.

To the best of my knowledge and after thorough research, taking OTC painkillers and making some adjustments to your routine and lifestyle can help you with Fluvoxamine-induced headaches. If these do not help and the headache does not subside, you should discuss this with your healthcare provider. They can better assess the situation and make changes to the prescription if needed.
