Headaches are among the most commonly reported side effects from ED medications. Some patients also describe mild pressure behind the eyes or a heavy sensation in the forehead or temples.
Why It Happens
ED medications cause vasodilation (widening of blood vessels), which can affect blood vessels in the head and around the eyes. This change in blood flow can lead to:
Tension-type headaches
Sinus-like pressure
Occasional eye heaviness or discomfort
What It Feels Like
Mild to moderate ache, often behind the eyes or at the temples
Dull pressure rather than sharp pain
Can start 30–60 minutes after dosing
Usually fades after a few hours
How to Manage
Hydration: Dehydration can worsen symptoms. Drink 1–2 glasses of water before and after dosing.
Avoid alcohol: Alcohol can amplify vasodilation and make symptoms worse.
Use over-the-counter pain relief: Paracetamol is generally well-tolerated. Avoid ibuprofen if you’re unsure about stomach tolerance.
Cool compress: A cold pack on the forehead or back of the neck may help reduce discomfort.
Dark, quiet room: Reducing visual and auditory stimulation can ease symptoms.
When to Speak With Your Doctor
If headaches are intense, frequent, or worsen over time
If pressure behind the eyes becomes painful or affects vision
If over-the-counter strategies don’t help
Your doctor may consider reducing the dose or changing medication.
Headaches and mild eye pressure are common with ED medications due to blood vessel changes. These side effects are usually manageable and short-lived. If they persist or impact your quality of life, contact your prescribing doctor through the portal.
