How to Find Myobloc in Stock Near You (Tools + Tips)

Tracking down Myobloc (rimabotulinumtoxinB) can feel like a scavenger hunt. This brand-only botulinum toxin type B injection is a specialty medication — not a drug stocked on the shelf at your corner pharmacy. But with the right approach, you can find it without spending your afternoon on hold. Here's a practical, step-by-step guide.

Step 1: Ask Your Prescriber First

Many neurologists and movement disorder specialists who prescribe Myobloc stock it directly in their office. Because Myobloc is administered by injection in a clinical setting, it's common for the prescribing physician's practice to purchase it and administer it on-site. Before you start calling pharmacies, ask your doctor's office: "Do you stock Myobloc, or will I need to obtain it separately?" In many cases, you won't need to go to a pharmacy at all.

Step 2: Call Specialty Pharmacies

If you do need to source Myobloc through a pharmacy, specialty pharmacies are your best starting point. These are pharmacies that specialize in high-cost, complex medications — including injectables, biologics, and cold-chain drugs. Some national specialty pharmacy networks to try:

CVS Specialty — separate from regular CVS retail; handles injectable and biologic medications

Walgreens Specialty — specialty pharmacy division with cold chain capability

Optum Rx / UnitedHealth Specialty

Accredo — major specialty pharmacy handling neurology medications

Hospital outpatient pharmacies — particularly those affiliated with neurology or movement disorder clinics

Step 3: Use medfinder to Make Calls for You

One of the most efficient ways to find Myobloc in stock is to use medfinder. You tell medfinder your medication, dosage, and location — medfinder then calls pharmacies in your area to check which ones have it available and texts you the results. This is especially useful for a specialty medication like Myobloc, where calling a dozen places yourself could take an entire morning.

Step 4: Contact Myobloc's Manufacturer for Help

Solstice Neurosciences (a Supernus Pharmaceuticals subsidiary) has a dedicated support line for Myobloc patients and healthcare providers. You can reach Myobloc patient support at 1-888-461-2255. They may be able to direct you to a local pharmacy or distributor that carries the medication, and they can also connect you with the manufacturer's copay assistance program if cost is a barrier.

Step 5: Check Your Insurance Network's Preferred Specialty Pharmacy

If you have commercial insurance and have obtained prior authorization for Myobloc, your insurance plan may have a preferred or required specialty pharmacy to dispense it. Check your insurance card or call the member services number on the back to ask which specialty pharmacy is in-network for specialty injectables. Using an in-network pharmacy can significantly reduce your out-of-pocket costs.

What to Have Ready When You Call

When calling pharmacies to check Myobloc availability, have the following information ready:

Drug name: Myobloc (rimabotulinumtoxinB)

Vial size needed: 2,500 units, 5,000 units, or 10,000 units

Quantity: how many vials you need for the treatment session

Your insurance information (if applicable)

Prior authorization number (if already obtained)

Keep in Mind: Cold Chain Requirements

Myobloc must be stored refrigerated at 36°F–46°F (2°C–8°C). It must not be frozen or shaken. When picking up or having it shipped, confirm the pharmacy uses appropriate cold chain packaging and that you can transport it properly. If you're having Myobloc shipped to your home, make sure there's a responsible adult available to receive it promptly.

Don't Wait Until You're Out

Because Myobloc effects last roughly 3–4 months, most patients are on a regular injection schedule. Start looking for your next vials 4–6 weeks before your appointment, especially if you've had access challenges in the past.
