Finding Your Best Blood Pressure Medicine
Why Different People Need Different Medicines
The safest and best medicine for you depends on your body and other health conditions. Your doctor will suggest medicines based on everything they know about your health.
For example, some blood pressure medicines can help with migraines. But that same medicine might not be the best treatment for someone else. This is why there’s no single best blood pressure medicine for everyone.
How the Process Usually Goes
- Start with 1-2 medicines
- See how well they’re working after 4 weeks
- Adjust the dose if needed
- Finding the right combination often takes a few tries
Why It Takes Time to Find the Right One
Even when your doctor picks the best medicine to start with, it might not be the best fit. There’s no way of knowing exactly how your body will react. This is why finding the right treatment usually takes a few tries.
Starting a Medication
What to Expect
- Checking in with your care provider every 2-4 weeks at first (may be more frequent if you have very high blood pressure)
- Medication adjustments, usually every 4 weeks
- May take time to find the safest medicine for you and your body
- You may have to change your dose or medicine in the future
How Long Does It Take for the Medicine to Work?
Most medicines take 4 weeks to take full effect.
Stopping or Changing a Medication
