Explains potential side effects and safety considerations for the Blood Flow Protocol and when to contact your clinician.

Updated over a week ago

This article applies specifically to the Blood Flow treatment plan.

Requirements may differ for other Maximus programs.


Medications used in the Blood Flow Protocol are generally well tolerated when used as directed. However, side effects can occur.

Your clinician reviews your health history to help minimize potential risks.

Possible Side Effects

Some individuals may experience temporary effects such as:

  • headache

  • facial flushing

  • nasal congestion

  • mild dizziness

  • digestive discomfort

These effects are typically mild and may decrease as your body adjusts.

Medication Interactions

Certain medications may interact with PDE-5 inhibitors.

You should inform your clinician about:

  • prescription medications

  • over-the-counter medications

  • supplements

  • recreational substances

One important interaction is with nitrate medications, which cannot be combined with PDE-5 inhibitors.

Your clinician evaluates potential interactions before recommending treatment.

Cardiovascular Considerations

Because these medications influence blood vessel function, individuals with certain cardiovascular conditions may require additional evaluation before treatment.

Your clinician will review your health history to determine whether the protocol is appropriate.

When to Message Your Clinician

Message your clinician if you:

  • experience unexpected symptoms

  • notice side effects that concern you

  • start new medications

  • have questions about your treatment

Your clinician can review your situation and provide guidance.
