Medication and comparison guides
Start with a medicine you know, or compare the ingredients and treatment patterns.
Understanding treatment
What are ED medicines, and how do they work?
Sildenafil and tadalafil belong to a group called phosphodiesterase type 5 inhibitors, or PDE5 inhibitors.
Medication comparison
Sildenafil or tadalafil: what is the difference?
Both are established oral treatments. The main practical differences concern timing and how long the response window lasts.
| What to compare | Sildenafil | Tadalafil |
|---|---|---|
| Recognizable brands | Viagra, Sidegra | Talafil, Casey |
| Typical timing | Usually taken around 1 hour before sex; response varies | As-needed treatment can begin working from around 30 minutes |
| Response window | A shorter window, usually several hours | Can last up to 36 hours |
| Food | A large meal can delay its effect | Food has less effect on timing |
| Treatment pattern | Usually taken when needed | As-needed or prescribed daily treatment, depending on the plan |
| Choosing an option | Your physician checks health, interactions, response and preferences. A longer response window does not mean a continuous erection. | |
Use the schedule prescribed for you. Brand availability is confirmed with the clinic; do not combine ED tablets or change the dose yourself.
Who this may help
What can contribute to erectile dysfunction?
ED often has more than one contributor. Identifying the pattern helps the physician choose safer and more effective first-line care.
Medication safety
How safe are erectile dysfunction medicines?
Sildenafil and tadalafil have an established role in ED care and are well tolerated by many patients. A brief health and medication review helps us select treatment with confidence.
- Never combine PDE5 inhibitors with nitrate medicines for chest pain or recreational nitrites such as poppers.
- Riociguat must not be combined with these medicines. Alpha-blockers and other medicines can also affect suitability or dosing.
- Tell the doctor about heart symptoms, recent heart attack or stroke, low blood pressure, and kidney, liver or eye conditions.
- If sexual activity has been medically discouraged, discuss that before starting treatment.
What to expect
Side effects and when to get help
Not everyone experiences side effects. Tell Kauri if a symptom bothers you so the treatment plan can be reviewed.
Your visit
What happens during an ED consultation at Kauri?
The visit is direct, private and clinically focused. You do not need to know the cause or choose a medicine before arriving.
Connected specialist care
What happens if tablets are unsuitable or do not work?
Not responding immediately does not always mean oral medication has failed. Kauri first reviews correct use, timing, tolerability, treatment expectations and whether an underlying contributor needs attention.
When first-line medical treatment is unsuitable or remains ineffective, we can recommend evaluation by a urologist or another appropriate specialist.
- Penile injections or intraurethral treatment
- Vacuum erection devices
- Assessment for selected procedural treatments
- Penile implant consultation
- Complex neurological, vascular or post-surgical ED
- Psychosexual or relationship-focused therapy
Patient questions
ED medication and treatment: frequently asked questions
Can Kauri treat erectile dysfunction?
Yes. Kauri provides private physician assessment and oral ED treatment with sildenafil or tadalafil when appropriate, with testing and follow-up tailored to your health. Specialist referral is available when another treatment is needed.
Do ED tablets increase sexual desire?
No. Sildenafil and tadalafil support the blood-flow response to sexual stimulation; they do not directly increase libido. Reduced desire deserves a separate review of health, hormones, medicines and emotional factors.
Is tadalafil better than sildenafil?
Neither is best for everyone. Tadalafil offers a longer response window, while sildenafil suits many people who prefer a shorter planned window. Your physician considers response, side effects, medicines and preferences.
Are Sidegra and Viagra the same medicine?
Both contain sildenafil. The brand, strength and availability can differ. Kauri reviews the active ingredient and appropriate prescription rather than choosing by brand alone.
Are ED medicines safe?
For many patients, prescribed ED medicines are effective and well tolerated. Safety depends on your cardiovascular health, other medicines and correct use. Never combine them with nitrates or poppers.
Can I take ED medicine with my usual medication?
Your physician must check the combination first. Nitrates and riociguat must not be combined with PDE5 inhibitors; alpha-blockers and some other medicines also require review. Bring a full medication and supplement list.
Will I need blood tests?
Tests are selected according to your symptoms and health history. Glucose or HbA1c, cholesterol and testosterone may help identify contributors; additional tests are arranged when relevant.
Does low testosterone always cause ED?
No. ED has several possible causes. Low testosterone can affect desire and erections in some patients, but TRT is considered only when evaluation supports testosterone deficiency.
What if the first tablet does not work?
Arrange a review before increasing the dose or mixing treatments. Timing, food, stimulation, anxiety and underlying health can affect response. Your physician can adjust the plan or recommend specialist care.
Do I have to take ED medication forever?
No. Treatment duration depends on the cause and your response. Some people use medication when needed; others benefit from ongoing treatment and periodic review. Treating contributing health problems can change what you need.
