Hello.
Strattera (atomoxetine) is primarily used for ADHD. One of the known side effects of Strattera is an increase in heart rate or blood pressure. This side effect can be concerning, especially for individuals with certain conditions like POTS (Postural Orthostatic Tachycardia Syndrome), which already affects heart rate.
For some people, side effects might diminish over several weeks as the body gets used to the medication. For others, side effects might persist as long as they're on the medication.
Given that you have multiple diagnoses, it's essential to consider potential interactions and cumulative effects. For example, both ADHD and POTS can have symptoms of elevated heart rate, and medication might exacerbate this. Additionally, anxiety from GAD could also contribute to an elevated heart rate.
If you're experiencing a side effect from a medication, it's crucial to communicate with your prescribing physician. They can provide guidance on whether the side effect is expected, if and when it might resolve, and if any changes to your treatment plan are needed.
An increase in resting heart rate from 70 to 87 BPM is notable. It's crucial to determine if this change is solely due to Strattera or if other factors might be involved. If Strattera is the primary cause, your doctor might need to reconsider the dose or explore alternative treatments.
Lifestyle factors, other medications, caffeine intake, and various other considerations could also play a role in heart rate changes. It would be a good idea to discuss all potential contributing factors with your healthcare provider.
Hope this helps.
