Alternatives to Zenzedi If You Can't Fill Your Prescription

If you've been struggling to find Zenzedi at your pharmacy, you're dealing with a frustration that thousands of patients share in 2026. The ongoing ADHD stimulant shortage has made brand-name Zenzedi one of the hardest medications to locate.

Pro tip: Before switching medications, try Medfinder to search for Zenzedi availability at pharmacies near you — you may find it closer than you think.

But if Zenzedi truly isn't available in your area, there are several effective alternatives worth discussing with your healthcare provider. Here's what you need to know about each one.

What Is Zenzedi?

Zenzedi is the brand name for dextroamphetamine sulfate, an immediate-release CNS stimulant. It belongs to the amphetamine drug class and works by increasing levels of dopamine and norepinephrine in the brain — two neurotransmitters that play key roles in attention, focus, and impulse control.

Zenzedi is FDA-approved to treat ADHD in pediatric patients ages 3–16 and narcolepsy. It is also widely prescribed off-label for adult ADHD. As a Schedule II controlled substance, it is subject to strict DEA manufacturing quotas and prescribing regulations.

Zenzedi is manufactured by Azurity Pharmaceuticals and comes in immediate-release tablets in doses from 2.5 mg to 30 mg. Unlike Adderall, which contains a 3:1 mix of dextroamphetamine and levoamphetamine, Zenzedi is pure dextroamphetamine — which some patients find provides a cleaner, more focused effect with fewer side effects.

How Does Zenzedi Work?

Dextroamphetamine, the active ingredient in Zenzedi, works by entering nerve terminals in the brain and triggering the release of dopamine and norepinephrine. It also blocks the reuptake of these neurotransmitters, keeping them active in the synaptic gap longer.

The result is improved focus, attention, and wakefulness. As an immediate-release formulation, Zenzedi typically takes effect within 30–60 minutes and lasts approximately 4–6 hours per dose. Most patients take it 2–3 times daily.

Because Zenzedi contains only the dextro-isomer of amphetamine (not the levo-isomer), it is more potent at dopamine receptor sites compared to mixed amphetamine products. This is why some patients specifically prefer Zenzedi or generic dextroamphetamine over Adderall. For a deeper dive, see our guide: How Does Zenzedi Work? Mechanism of Action Explained.

Alternative Medications to Zenzedi

If you can't find Zenzedi, these are the most commonly considered alternatives. Always consult with your healthcare provider before making any changes to your medication.

1. Generic Dextroamphetamine Sulfate (IR Tablets)

This is the closest alternative to Zenzedi because it contains the exact same active ingredient — dextroamphetamine sulfate — in the same immediate-release tablet form. The only difference is the manufacturer and inactive ingredients (fillers, dyes, binders).

• Why consider it: Same drug, same doses, same duration of action. Significantly cheaper ($30–$80 with coupons vs. $550+ for brand Zenzedi).
• Availability: More widely stocked than brand Zenzedi, though still affected by the broader stimulant shortage.
• Caveat: Some patients report differences in how generics feel compared to the brand, likely due to variations in inactive ingredients and absorption rates.

2. Adderall (Mixed Amphetamine Salts)

Adderall contains a combination of dextroamphetamine and levoamphetamine in a 3:1 ratio. It's available as both immediate-release (Adderall) and extended-release (Adderall XR) tablets.

• Why consider it: The most widely prescribed ADHD stimulant in the U.S., so it's more commonly stocked at pharmacies. The mixed salts may provide a slightly different effect profile that works better for some patients.
• Key difference: The levoamphetamine component adds more norepinephrine activity, which some patients experience as increased physical energy or peripheral stimulation.
• Availability: Generic Adderall IR is one of the more available stimulants, though it has also experienced shortages.

3. Vyvanse (Lisdexamfetamine)

Vyvanse is a prodrug of dextroamphetamine — meaning it converts to dextroamphetamine in your body after being absorbed. This creates a smoother onset and longer duration of action (up to 12–14 hours).

• Why consider it: Same active metabolite as Zenzedi. Longer-acting, which means one dose per day instead of 2–3. Lower abuse potential due to the prodrug mechanism. Generic lisdexamfetamine became available in 2023.
• Key difference: You lose the ability to fine-tune dosing throughout the day that IR formulations like Zenzedi provide.
• Availability: Generic Vyvanse availability has been improving but is still inconsistent in some areas.

4. Methylphenidate (Ritalin, Concerta, Focalin)

Methylphenidate is a different stimulant class from amphetamines. It works primarily by blocking the reuptake of dopamine and norepinephrine (rather than triggering their release like amphetamines do).

• Why consider it: Not affected by the same DEA amphetamine production quotas, so supply may be more stable. Available in numerous formulations (IR, ER, patch, liquid). Well-studied with decades of clinical use.
• Key difference: Different mechanism of action means some patients respond better to one class than the other. Side effect profiles differ slightly — methylphenidate may cause less appetite suppression for some patients.
• Availability: Generally more available than amphetamine products in 2026.

Final Thoughts

If you can't find Zenzedi, you have several effective alternatives to discuss with your prescriber:

1. Generic dextroamphetamine — same active ingredient, more widely available, much cheaper
2. Adderall — mixed amphetamine salts, most commonly stocked stimulant
3. Vyvanse — long-acting dextroamphetamine prodrug, one dose per day
4. Methylphenidate — different stimulant class, potentially more stable supply
