There is no single right treatment for ED. The best option depends on the cause, your other health conditions, what you have tried before, and what you can stick with. This page walks through every option used in South Africa, what it is for, and roughly where it sits in the order of things to try.
First Line: Oral PDE5 Inhibitors
The big four oral medications are sildenafil, tadalafil, vardenafil, and avanafil. In South Africa, sildenafil and tadalafil are the most commonly prescribed and are widely available as generics. They all belong to the same family, called PDE5 inhibitors, and they all work by improving blood flow to the penis when you are aroused.
Worth being clear on one thing: these are not aphrodisiacs. They do nothing without sexual stimulation. They simply make the plumbing respond properly when arousal is there.
- Sildenafil (originally Viagra, now widely generic). Onset 30 to 60 minutes. Works for around four hours. Taken on demand.
- Tadalafil (originally Cialis, now widely generic). Onset 30 to 60 minutes. Works for up to 36 hours, which is why it is sometimes called the weekend pill. Can also be taken in a low daily dose.
- Vardenafil (Levitra). Similar profile to sildenafil. Slightly more selective in its mechanism.
- Avanafil (Stendra). Newer option with a faster onset. Less commonly available in SA.
Roughly seven in ten men respond well to first line oral medication. We compare them in detail on the sildenafil vs tadalafil vs vardenafil page.
Get The Right Tablet At The Right Dose
An online consultation matches the medication and dose to your medical history. It takes around ten minutes.
Start ConsultationLifestyle Changes
The least exciting answer but often the most important. Lifestyle changes do two things: they reduce ED itself, and they make the medication work better when you do use it.
The big levers in order of impact for most men:
- Cardio exercise. Three to four sessions a week of anything that elevates the heart rate for 30 minutes. Running, cycling, swimming, brisk walking. The single most studied lifestyle change with real effect on ED.
- Stop smoking. The vascular damage starts to reverse within months.
- Manage weight. Even modest weight loss in overweight men improves erectile function and testosterone.
- Cut excess alcohol. Heavy drinking damages both nerves and erections directly.
- Sleep. Treating untreated sleep apnoea has a marked effect in affected men.
- Stress and anxiety. Brief counselling or even a few sessions of a course like Mindfulness Based Stress Reduction can help.
Psychological Treatment
For ED with a clear psychological component, particularly performance anxiety in younger men, brief therapy is often more effective than medication alone. Sex therapy, CBT, and couples counselling are the standard approaches.
A common approach is to combine a short course of medication (to break the anxiety cycle by ensuring success) with a few sessions of therapy. The medication is then often reduced or stopped over time.
Hormone Treatment
For the small subset of men with genuinely low testosterone, testosterone replacement therapy (TRT) can help. Important to be honest about this: TRT is not an ED treatment for most men. If your testosterone is normal, TRT will not fix your erection. If it is low and there are other symptoms (fatigue, low mood, loss of muscle mass), it can make a real difference.
A blood test sorts this out. TRT in SA needs prescribing and monitoring by a doctor.
Second Line: Injections, Pellets, And Devices
For men who do not respond to oral medication or cannot take it, there are well established second line options. These are not commonly first line because they involve more effort or are more invasive.
Intracavernosal injection (ICI)
A small injection of alprostadil (or a combination called bimix or trimix) directly into the side of the penis before sex. Effective in most men who do not respond to tablets. Sounds dramatic, but it is a small fine needle and most men adapt quickly. Onset is 5 to 15 minutes.
Intraurethral pellet (MUSE)
A small pellet of alprostadil placed into the urethra using a thin applicator. Less effective than injection but avoids the needle.
Vacuum erection device (VED)
A clear plastic cylinder placed over the penis and a hand pump that creates a vacuum. The vacuum draws blood in, then a constriction ring is placed at the base to maintain it. Works mechanically rather than chemically. Useful when medication is contraindicated, and often used after prostate surgery.
Third Line: Surgery
Penile implant surgery is the final option when nothing else works. A device is surgically implanted that allows the man to produce an erection on demand. The satisfaction rates are very high in carefully selected men, but it is irreversible and only considered after all other options have been tried.
Implants are not commonly placed in SA but are available in urological centres in major cities.
What Most Men Actually Do
The honest pattern looks like this:
- An online or in person consultation
- A prescription for sildenafil or tadalafil at a starting dose
- A frank conversation about cardio, alcohol, and sleep
- Follow up after a few weeks to adjust dose or switch medication if needed
That sequence works for the majority. The rest are stepped up to second line treatments through a urologist.

Frequently Asked
For most men, an oral PDE5 inhibitor (sildenafil, tadalafil, or vardenafil) at an appropriate dose is the first line. Lifestyle adjustments work alongside. Second line options are used when first line is not effective or not tolerated.
Sildenafil takes 30 to 60 minutes for the effect, lasts around four hours. Tadalafil takes a similar time, but lasts up to 36 hours, which is why some men prefer it. Lifestyle changes show benefit over weeks to months.
Not necessarily. Many men use medication for a period while addressing underlying causes, and over time some can reduce or stop the medication. Others use it long term, which is fine and safe.
Some have weak evidence (L arginine, panax ginseng, DHEA) but none come close to prescription medication for effectiveness. Be cautious with unregulated herbal products. They sometimes contain undisclosed prescription drugs in unknown doses.
