Non-Stimulant ADHD Meds vs Saffron: What Parents Should Know
If stimulants like Ritalin or Adderall didn't work for your child or caused too many side effects your doctor may have mentioned non-stimulant ADHD medications. These work differently and take longer but they don't have the same crash or appetite loss.
This guide compares the four non-stimulant meds approved for kids (guanfacine, atomoxetine, viloxazine and clonidine) to saffron. We'll cover how they work, side effects, how long they take and whether your child can take saffron with them.
What non-stimulant ADHD meds are there for kids?
Four medications are approved in the US for kids with ADHD:
- Guanfacine ER (Intuniv) - ages 6-17
- Atomoxetine (Strattera) - ages 6+
- Viloxazine (Qelbree) - ages 6+
- Clonidine ER (Kapvay) - ages 6-17
All four are prescription-only. Doctors usually try stimulants first (Ritalin, Adderall, Concerta) because they work faster and have more research backing them. Non-stimulants are second-line options when stimulants don't work or aren't tolerated.
In Australia:
Guanfacine and atomoxetine are available on the PBS (Pharmaceutical Benefits Scheme) after stimulants have been tried. Viloxazine and clonidine ER are not available.
In the UK:
Guanfacine and atomoxetine are licensed for ADHD when stimulants don't suit. Viloxazine is not available. Clonidine ER is sometimes used off-label by specialists.
How do they work and how long until they work?
None of these are stimulants. They don't force dopamine or norepinephrine spikes. They work on different brain receptors and neurotransmitter systems.
| Medication | How it works | Time to see results |
|---|---|---|
| Guanfacine (Intuniv) | Affects norepinephrine receptors in the prefrontal cortex. Improves working memory and impulse control | About 2 weeks |
| Atomoxetine (Strattera) | Blocks norepinephrine reuptake. Increases norepinephrine in the brain | Up to a month, sometimes longer |
| Viloxazine (Qelbree) | Increases norepinephrine and serotonin. Exact mechanism still being studied | From week 1 in trials but full effect may take longer |
| Clonidine (Kapvay) | Similar to guanfacine. Affects norepinephrine receptors | Trials measured at 5 weeks |
All four take longer to work than stimulants (which work in 30-60 minutes). You need patience and consistency.
Saffron for comparison:
Believed to reduce dopamine reuptake, helping the brain recycle existing dopamine. Most parents see changes in 2-4 weeks. Not as fast as stimulants but similar timing to non-stimulant meds.
What are the side effects?
Non-stimulants avoid the appetite loss and sleep problems common with stimulants but they have their own side effects.
| Medication | Most common side effect (vs placebo) | Boxed warning |
|---|---|---|
| Guanfacine | Sleepiness 38% vs 11% | None (but taper when stopping to avoid blood pressure rebound) |
| Atomoxetine | Stomach pain 18% vs 10%; decreased appetite 16% vs 4% | Suicidal thoughts (0.4% vs 0%) |
| Viloxazine | Sleepiness 16% vs 4% | Suicidal thoughts (0.9% vs 0.4%) |
| Clonidine | Sleepiness 31-38% vs 4% | None (but taper when stopping) |
Sources: Intuniv, Strattera, Qelbree and Kapvay prescribing information.
Sleepiness is the big one. Guanfacine and clonidine both cause significant drowsiness especially in the first few weeks. Some kids adjust. Others stay tired. Doctors usually start at a low dose and increase slowly.
Suicidal thoughts warning:
Atomoxetine and viloxazine carry FDA boxed warnings. The risk is small (under 1%) but real. Parents and doctors need to watch for mood changes, new or worsening depression or talk of self-harm especially in the first few weeks.
Saffron side effects (for comparison):
In the 2019 trial comparing saffron to methylphenidate (Ritalin), 13% of kids on saffron reported side effects vs 78% on the stimulant. Most were mild stomach upset.
Can my child take saffron with guanfacine or Strattera?
There are no documented interactions between saffron and any of these four medications in the medical literature.
That said you must talk to your child's doctor before combining them. Your doctor needs to know everything your child is taking so they can monitor for unexpected interactions or changes in how the medication works.
Some parents use saffron to smooth out side effects or fill gaps when the medication isn't enough. These are decisions to make with your doctor not on your own.
Are they available in Australia and the UK?
Australia:
- Guanfacine: Yes, PBS listed (subsidized after stimulants tried)
- Atomoxetine: Yes, PBS listed
- Viloxazine: No
- Clonidine ER: No (immediate-release clonidine exists but not the ER version approved for ADHD)
UK:
- Guanfacine: Yes, licensed for ADHD when stimulants don't suit
- Atomoxetine: Yes, licensed
- Viloxazine: No
- Clonidine: Off-label use by specialists only (not formally licensed for ADHD)
If you're outside the US your options are more limited.
Is there a natural non-stimulant option?
Saffron is the closest thing to a natural non-stimulant option with research backing it.
Saffron is not a stimulant. It doesn't spike dopamine or increase heart rate. It's believed to support steady dopamine levels by reducing reuptake. The effect builds over 2-4 weeks similar to non-stimulant medications.
In a 2019 trial saffron was compared head-to-head with methylphenidate (a stimulant not a non-stimulant but still relevant). Both groups improved equally. Side effects: 13% on saffron vs 78% on the medication.
No trial has compared saffron directly to guanfacine, Strattera, Qelbree or clonidine. We can't say saffron works as well as those medications because the comparison hasn't been done.
What we can say: saffron has been studied in about 270 kids and teens over 6 weeks to 3 months with positive results and minimal side effects. If you're looking for a non-medication option before trying prescriptions or if your child can't tolerate medication side effects saffron is a researched alternative.
For the full research breakdown see our saffron for kids guide.
Has saffron been tested against them?
No. No trial has compared saffron to guanfacine, atomoxetine, viloxazine or clonidine.
The only head-to-head comparison is saffron vs methylphenidate (Ritalin) which is a stimulant. That trial showed equal effectiveness with far fewer side effects for saffron.
Without direct comparisons we can't make claims about saffron working as well as non-stimulant meds. We can only say saffron has its own body of research (four trials, 270 kids and teens) showing it helps with ADHD symptoms.
Non-stimulant meds vs saffron: side by side
| Non-Stimulant Meds | Saffron | |
|---|---|---|
| Prescription required | Yes | No |
| Time to work | 2 weeks to 1+ month | 2-4 weeks |
| Most common side effect | Sleepiness (guanfacine, clonidine 30-38%) | Mild stomach upset (~10%) |
| Boxed warnings | Yes (Strattera, Qelbree: suicidal thoughts) | No |
| Head-to-head with other ADHD meds | Not against each other | Yes (vs Ritalin, equal results) |
| Trials in kids | Many (decades of research) | 4 trials, ~270 participants |
| Where they sit in guidelines | Second-line (after stimulants) | Not in formal guidelines (supplement, not medication) |
| Availability | US: all four. AU/UK: limited | US, AU, UK, EU, Canada |
Non-stimulant meds have more total research and are part of formal treatment guidelines. Saffron has less total research but no prescription requirement and fewer side effects.
The bottom line
Non-stimulant ADHD medications (guanfacine, Strattera, Qelbree, clonidine) work through different brain pathways than stimulants. They take 2 weeks to a month to show results. The most common side effect is sleepiness (30-40% for guanfacine and clonidine). Two of them carry boxed warnings for suicidal thoughts.
Saffron is not a medication but it's been studied in kids with ADHD. Four trials, 270 participants, 2-4 weeks to see results, 13% side effect rate (mostly mild stomach upset). No trial has compared saffron to non-stimulant meds directly.
If stimulants didn't work for your child non-stimulant meds are the standard next step. If you want to try a non-medication option first or your child can't tolerate medication side effects saffron is a researched alternative.
Always talk to your child's doctor before starting, stopping or combining anything.
Frequently Asked Questions
There are no documented interactions but you must talk to your doctor first. Never adjust medication doses on your own.
It varies by child. Viloxazine tends to cause less sleepiness than guanfacine or clonidine but it carries a suicidal thoughts warning. Strattera has more stomach side effects. There's no perfect option. Your doctor will help you weigh the trade-offs.
For most kids no. A large review of 133 trials found stimulants more effective than non-stimulants. But effectiveness isn't everything. If stimulants cause severe side effects a less effective medication that your child tolerates is better than a highly effective one they can't take.
Mighty Minds is formulated for kids. If you're an adult looking for saffron we make Saffron Plus Capsules with a higher dose plus adaptogens.
ADHD treatment often requires trial and error. Medication, behavioral therapy, school accommodations and parent training all play a role. If you've tried multiple options without success ask your doctor for a referral to a specialist (developmental pediatrician or child psychiatrist).
