Combination Therapy for ED: 6 Options That Work Better

At BlueChew, we know ED treatment isn't one-size-fits-all. Some men respond great to a single medication, while others need a little extra support. That's where combination therapy comes in: using two or more treatments that work in different ways to get better results.

Why combine? Research shows that using more than one approach can make a real difference, especially for men who don't fully respond to a single treatment. Below, we'll break down what combination therapy is, six combinations worth knowing, and how BlueChew's MAX, VMAX, and GOLD fit in.

• Combination therapy means using two or more ED treatments at the same time.
• Research shows combination approaches often work better than a single treatment, especially for men who don't fully respond to one.
• Options include medication plus lifestyle changes, testosterone therapy, devices, shockwave therapy, therapy, or a second PDE5 inhibitor.
• BlueChew's MAX and VMAX pair a fast-acting ingredient with long-lasting tadalafil, and GOLD adds apomorphine and oxytocin.
• Combination treatments should only be prescribed by a provider. Never combine ED medications on your own.

Combination therapy for ED means using two or more treatments at the same time. Instead of putting all your hope in one pill, shot, or device, you stack treatments that work in different ways, tackling erection issues from multiple angles.

Think of it like training for a marathon: running helps, but pairing it with strength training, sleep, and nutrition gives you the best shot at the finish line. For erections, that might look like medication plus lifestyle changes, medication plus a device, or even two PDE5 inhibitors together.

1. Medication + Lifestyle Changes

Taking a PDE5 inhibitor while improving your diet, exercise, and sleep often leads to better results. Research found men who paired medication with aerobic exercise had better erection scores than men on medication alone.

A Mediterranean-style diet is linked to better erectile function too, and in men with sleep apnea, research found the biggest improvements when sleep treatment was combined with ED medication. There are plenty of natural ways to enhance your erections alongside treatment.

2. Medication + Testosterone Therapy

For some men who don't respond to PDE5 inhibitors alone, low testosterone is part of the problem. Testosterone is closely tied to sex drive and erections, and a systematic review found that treating low testosterone can make PDE5 inhibitors more effective. This only applies to men with confirmed low testosterone, so a blood test comes first.

3. Medication + Vacuum Erection Devices

Vacuum erection devices (VEDs) use suction to pull blood into the penis, and a ring helps keep it there. Add a PDE5 inhibitor, and you're improving blood flow chemically and mechanically. Studies show the combination can lead to better erections than either alone, and other research found it can improve sexual satisfaction.

4. Medication + Shockwave Therapy

Low-intensity shockwave therapy uses sound waves to stimulate blood vessel growth in the penis. It's been studied in men who don't respond to PDE5 inhibitors alone: in one sham-controlled trial, 54% of men who couldn't have sex on a PDE5 inhibitor were able to after shockwave therapy, compared with none in the sham group, and in a 12-month follow-up study, most men who improved kept their results a year later. A review of sham-controlled trials found mostly positive results, though treatment protocols vary widely. It's still being studied, so talk to a urologist about whether it's right for you.

5. Medication + Talk Therapy

Performance anxiety is one of the biggest erection killers, and it can get in the way of even the strongest medication. Research shows men who combined cognitive-behavioral therapy (CBT) with ED medication reported better erectile function and higher satisfaction than those on medication alone. Treating both the mind and the body often works best.

6. Two PDE5 Inhibitors Together

One of the most promising approaches pairs two PDE5 inhibitors: tadalafil (long-acting) with sildenafil or vardenafil (faster-acting). The idea is a quick start plus coverage for up to 36 hours.

The research is encouraging. A 2014 study found men taking tadalafil and sildenafil together had stronger erections and greater satisfaction than men on tadalafil alone, without more side effects. A 2024 study found men who hadn't responded to one medication saw significant improvements in rigidity and function on a combination. If one ingredient alone hasn't done the trick, it's a common reason some men don't respond to Viagra or Cialis alone.

BlueChew offers three combination formulas, each in a single sublingual tablet that typically starts working within 15–30 minutes and lasts up to 36 hours.

MAX pairs sildenafil and tadalafil for a quick response and long-lasting coverage. VMAX swaps in vardenafil, which some men respond to better than sildenafil. GOLD goes a step further, adding apomorphine, which acts on arousal pathways in the brain, and oxytocin, linked to intimacy. Each has its strengths, as the GOLD vs. MAX and VMAX comparison shows.

Is Combination Therapy Safe?

When it's prescribed by a provider, yes, combination therapy can be safe and effective. A few ground rules:

• Never combine separate ED medications on your own. BlueChew's combinations come in a single prescribed tablet at set doses.
• Don't take any ED medication with nitrates for chest pain or guanylate cyclase stimulators, because the combination can cause a dangerous drop in blood pressure.
• Expect the usual side effects: headache, flushing, nasal congestion, and indigestion. GOLD can also cause nausea or dizziness.

Rare but serious side effects, like chest pain or an erection lasting more than 4 hours, need emergency care.

When one treatment doesn't fully deliver, combining approaches often can, whether that's pairing medication with exercise, therapy, or a second ingredient. If your ED medication isn't working like it used to, a provider can help you figure out what to add.

With MAX, VMAX, and GOLD, BlueChew makes combination therapy simple: one tablet, one prescription, and coverage for whenever the moment strikes.

What is combination therapy for erectile dysfunction?

Combination therapy means using two or more ED treatments together, such as medication plus lifestyle changes, testosterone therapy, a vacuum device, talk therapy, or a second PDE5 inhibitor. BlueChew's combination formulas pair two PDE5 inhibitors in one tablet.

Why would someone combine two ED medications?

Some men don't get their best results from one medication. Pairing tadalafil with sildenafil or vardenafil can improve erection firmness and satisfaction, and research found it didn't increase side effects.

Is it safe to combine ED medications?

Only when a provider prescribes the combination. Never mix separate ED medications on your own, and never take ED medication with nitrates.

What's the difference between MAX, VMAX, and GOLD?

MAX combines sildenafil and tadalafil. VMAX combines vardenafil and tadalafil. GOLD combines sildenafil and tadalafil with apomorphine and oxytocin to support arousal as well as erections. All three typically start working within 15–30 minutes and last up to 36 hours.

Will I have more side effects with combination therapy?

Not necessarily. In research, combining tadalafil and sildenafil didn't increase side effects compared with one medication alone. GOLD's apomorphine can also cause nausea or dizziness, especially the first time.

How do I know if I need combination therapy?

If a single medication gives you partial or inconsistent results, or performance anxiety is getting in the way, a provider may suggest a combination. Talk to your provider about what fits your situation.
