Does Hydrochlorothiazide cause headaches? 

Does Hydrochlorothiazide cause headaches? 

Yes, Hydrochlorothiazide can cause headaches. It is considered a possible initial side effect of this medication, but it is usually nothing to worry about. Headaches on Hydrochlorothiazide usually begin to go away as your body adjusts to the medication. 

Most people don’t feel severe headaches. However, meds affect people differently. If Hydrochlorothiazide causes unbearable headaches in your case, reach out to your healthcare provider. 

The incidence of headaches with Hydrochlorothiazide

The incidence of headaches with Hydrochlorothiazide can vary among individuals. Research suggests that headaches are a possible side effect of this medication and the drug can also trigger hair loss in some people (1). However, not everyone who takes Hydrochlorothiazide will experience these side effects. 

The exact incidence is not well defined, as it can depend on factors such as the dose, duration of treatment, and individual susceptibility. It is always important to consult with your healthcare provider if you experience persistent or severe headaches while taking Hydrochlorothiazide.

What factors can contribute to Hydrochlorothiazide-induced headaches?

When it comes to Hydrochlorothiazide-induced headaches, several factors can contribute to their occurrence. These factors may include (2,3):

  • Dehydration: Hydrochlorothiazide is a diuretic medication that increases urine production, which can lead to dehydration if sufficient fluids are not consumed. Dehydration can trigger headaches.
  • Electrolyte imbalance: Hydrochlorothiazide can cause a loss of electrolytes such as sodium and potassium. An imbalance in these electrolytes can potentially lead to headaches.
  • Blood pressure changes: Hydrochlorothiazide is primarily used to treat high blood pressure. Abrupt changes in blood pressure, especially if it drops too low, can cause headaches.
  • Medication interactions: Hydrochlorothiazide may interact with other medications, such as nonsteroidal anti-inflammatory drugs (NSAIDs), that can increase the risk of developing headaches.
  • Individual sensitivity: Some individuals may be more sensitive to the effects of Hydrochlorothiazide and may experience headaches as a side effect.

How to get rid of headaches caused by Hydrochlorothiazide? 

You can take OTC painkillers like Tylenol (Acetaminophen) and Advil/Motrin (Ibuprofen) to get rid of Hydrochlorothiazide-induced headaches. These meds are usually enough to deal with your headache while your body adjusts to the medication. 

You can also try to avoid things that can trigger headaches or make your existing headache worse, like using smart gadgets, exposure to sharp lights and sounds, too much exertion, etc. 

However, if your headaches don’t go away within a few days or become severe, talk to your healthcare provider.
