How to Make ED Medication Work Better: Factors That Actually Matter
Reviewed by the Kamagra AUS Pharmacy Team on 6 January 2026 · Next review June 2027
Summary
A look at the everyday factors — timing with food, arousal, alcohol, and stress — that genuinely affect how well ED medication performs, without touching on dosing.

It's Rarely Just About the Medicine
When a PDE5 inhibitor like sildenafil doesn't seem to work as well as expected, the instinct is often to assume the medicine itself is the problem. In reality, how well these medicines perform is influenced by a range of everyday factors that have nothing to do with the active ingredient's strength. Understanding these factors — rather than changing your own dose — is usually the more useful first step, and it's worth raising any of them with your prescriber if something isn't working as expected.
Timing Relative to Food
What and when you eat can genuinely change how a PDE5 inhibitor behaves in your body:
- A large, high-fat meal shortly before taking sildenafil can slow down how quickly it's absorbed, which may delay or blunt its effect.
- Taking the medicine on a lighter stomach, or well before or after a heavy meal, tends to give more predictable absorption for many people.
- This effect varies between individuals, and not everyone notices a difference — but it's a well-recognised factor worth being aware of.
Arousal Still Matters
This is one of the most misunderstood points about PDE5 inhibitors: they are not a substitute for sexual stimulation. The medicine supports the physical mechanics of an erection, but arousal — physical and mental — is still required for it to have an effect. Adequate foreplay, a relaxed environment, and genuine interest in the moment all still matter as much as they would without any medicine involved.
Alcohol
Alcohol is a common factor that undermines how well ED medication performs:
- Alcohol is a vasodilator and central nervous system depressant, and in combination with a PDE5 inhibitor it can increase side effects such as dizziness, flushing, or a drop in blood pressure.
- Heavier drinking is also independently linked with difficulty achieving or maintaining an erection, regardless of medication.
- Keeping alcohol light, or avoiding it altogether around the time you take your medicine, is a reasonable general approach — but check with your prescriber if you have specific questions.
Stress, Anxiety, and Mental State
Psychological factors can outweigh anything happening at a physical level:
- Performance anxiety — worrying about whether the medicine will "work" — can itself interfere with arousal, creating a frustrating cycle.
- General life stress, relationship tension, or fatigue can all reduce sexual response independently of any medicine.
- Some people find that addressing stress through exercise, sleep, open communication with a partner, or professional support (such as a GP or counsellor) makes a meaningful difference alongside medical treatment — though results vary from person to person and there's no assurance of a particular outcome.
General Health Factors
Broader lifestyle and health factors that some people find helpful to pay attention to include:
- Regular physical activity and maintaining a healthy weight, which support overall cardiovascular health.
- Managing underlying conditions like high blood pressure, high cholesterol, or diabetes, all of which are linked to erectile function.
- Reducing smoking, which affects blood vessel health.
None of these come with a promised outcome, and the evidence for how much difference lifestyle change makes varies from person to person — but they're reasonable general health measures regardless of ED medication.
What Not to Do
It's worth being clear about what isn't the right response if a medicine seems underwhelming:
- Don't take an extra dose or take it more often than prescribed.
- Don't mix it with other erectile dysfunction products without medical advice.
- Don't combine it with nitrate medicines under any circumstances — this combination can cause a dangerous drop in blood pressure.
If something consistently isn't working the way you expected, the right move is to go back to your prescriber rather than experimenting on your own. They may adjust the medicine, the approach, or investigate other contributing health factors, and they can also check whether an underlying condition might be playing a role. You can browse the erectile dysfunction category to see the range of prescription options available, but any change to what you take, or how you take it, should always be made in consultation with a doctor or pharmacist.

Frequently asked questions
Does eating before taking sildenafil really make a difference?+
For some people, yes. A large, high-fat meal can slow absorption and delay or reduce the effect. Many people find lighter meals or an empty stomach gives more predictable results, though this varies between individuals.
Why doesn't the medicine work if I'm not aroused?+
PDE5 inhibitors support blood flow in response to sexual stimulation rather than producing an erection independently. Arousal — both physical and mental — is still a necessary part of the process.
Can stress alone stop ED medication from working?+
Stress and performance anxiety can meaningfully interfere with sexual response, sometimes enough to outweigh the physical support the medicine provides. This is worth discussing with a doctor if it's a recurring issue.
Is it safe to have a drink before taking ED medication?+
Light drinking may be fine for some people, but alcohol can increase side effects and independently affect erectile function. If in doubt, ask your prescriber for guidance specific to your health history.
Should I take a higher dose if the standard one isn't working?+
No — never adjust your own dose. If a medicine isn't performing as expected, speak to your prescriber, who can review contributing factors and adjust your treatment appropriately.
