Why doctors warn against them:
These drugs work by narrowing blood vessels. Unfortunately, that same mechanism can:
Raise blood pressure
Increase heart rate
Trigger palpitations
Doctors frequently see spikes in blood pressure during cold season because patients don’t realize their “simple cold medicine” is affecting their cardiovascular system.
People with hypertension are often advised to:
Avoid decongestants
Choose “heart-safe” or “blood pressure–friendly” alternatives
Read labels carefully
- Certain Migraine and Headache Medications
Some migraine medications work by constricting blood vessels in the brain.
While effective for pain, this action can:
Increase systemic blood pressure
Stress the cardiovascular system
Doctors may recommend alternative treatments or careful monitoring for patients with hypertension who suffer from migraines.
This is a perfect example of why self-medicating without medical guidance can be risky.
- Hormonal Medications and Therapies
Hormones have powerful effects on the body, including blood pressure regulation.
Some hormonal treatments may:
Increase fluid retention
Affect vascular tone
Interact with blood pressure medications
Doctors often monitor blood pressure more closely when patients:
Start hormone replacement therapy
Use certain contraceptives
Undergo hormonal treatments
This doesn’t mean these medications are unsafe—but they require individual assessment.
- Certain Antidepressants and Mental Health Medications
Mental health treatment is essential, and no one should stop psychiatric medication without medical supervision.
However, doctors acknowledge that some medications used for:
Depression
Anxiety
Attention disorders
Can affect:
Heart rate
Blood vessel tone
Blood pressure
