The Potential Side Effects of Sertraline

Sertraline is known for its effectiveness in treating depression and anxiety, but like any medication, it can come with side effects. Palpitations are among the cardiovascular side effects that some individuals may experience. These palpitations are characterized by the feeling of your heart racing, fluttering, or skipping beats.

Understanding Palpitations

Palpitations are not uncommon, and they can be triggered by various factors. In the context of sertraline use, it’s important to differentiate between occasional palpitations and those that are directly linked to the medication. Palpitations can be a result of anxiety, caffeine intake, or even strenuous physical activity.

Factors Influencing Palpitations:

  • Individual Sensitivity: People react differently to medications, and some may be more prone to palpitations than others while taking sertraline.
  • Interaction with Other Medications: If you’re taking other drugs along with sertraline, there’s a possibility of drug interactions that could contribute to palpitations.
