Dry Mouth from Medications | Rheo™ Oral Pouches by OPS
Is your medication drying out your mouth?
Your treatment is doing its job — but it left your mouth bone-dry. Rheo™ brings hours of hydration and saliva support, without getting in the way of your meds.
The medication is helping you — but the dry mouth that came with it is miserable.
GLP-1s for weight and blood sugar. Stimulants for ADHD. Antidepressants, blood-pressure pills, allergy meds — and radiation or chemo for cancer. They can all leave your mouth dry as a side effect, because they slow the saliva your mouth depends on.
You’re not going to stop a medication that’s helping you. The goal is simple: bring the moisture back. Rheo™ gives you hours of hydration and stimulates your own saliva — a discreet pouch you can use anytime, right alongside your treatment.
- Constant dryness from a daily pill. If you take it every day, the dry mouth is there every day too.
- A dry mouth that hurts your teeth. Reduced saliva raises your risk of cavities and infection.
- Bad breath and trouble swallowing. Everyday side effects that chip away at your confidence.
- Not wanting to quit what’s working. You need relief that fits around your treatment, not instead of it.
Medications that commonly cause dry mouth
If any of these are part of your routine, your dry mouth may be a side effect — not a coincidence.
GLP-1 medications
Popular weight and blood-sugar medications frequently list dry mouth among their side effects.
ADHD stimulants
Stimulant medications are well known for reducing saliva and leaving your mouth dry.
Blood pressure & antidepressants
Two of the most common prescription categories that cause chronic dry mouth.
Cancer treatment
Radiation and chemotherapy for head, neck, and throat cancers can sharply reduce saliva.
Allergy & cold medicine
Antihistamines and decongestants dry out your whole system, mouth included.
Many others
Hundreds of prescriptions can reduce saliva — if your dry mouth started with a new med, that’s often why.
Relief in three easy steps
No routine to learn. One pouch, whenever you need it.
Tuck
Slip one pouch comfortably between your lip and gum. No chewing, spraying, or dissolving.
Swish
A small sip of water or your own saliva activates the hydration formula right away.
Enjoy
Keep it in for hours of comfort — and it keeps supporting your natural saliva after it’s out.
Four active ingredients, one pouch
Thoughtfully engineered by a dentist to hydrate, stimulate saliva, and protect your teeth.
Xylitol
Stimulates natural saliva and helps starve decay-causing bacteria.
Nano-Hydroxyapatite
Helps protect and strengthen enamel, the building block of teeth.
Hyaluronic Acid
Attracts and holds moisture to soothe dry oral tissue.
Citric Acid

They tried everything. Then they tried Rheo™.
“The pouches are a great alternative to lozenges or sprays to relieve dry mouth from my medications. Highly recommend.”
“By far the best I’ve used — long-lasting moisture and relief, not just a quick fix.”
“One pouch lasts about 3 hours for me and it’s completely discreet. The best option I’ve tried.”
“We built the dry-mouth solution we couldn’t find for our own patients.”
Rheo™ was created by a husband-and-wife team — Dr. Ryan, a dentist, and Dr. Rachel, a pharmacist — who saw every day how few dry-mouth products actually worked. Most only masked the problem for a few minutes. So they engineered a pouch that lasts, supports your natural saliva, and protects your teeth while it works.

Your dry-mouth questions, answered
Will Rheo™ interfere with my medication?
Rheo™ is a sugar-free oral hydration pouch, not a drug — it’s designed to relieve dry-mouth discomfort alongside your routine. As always, check with your pharmacist or doctor if you have questions.
How long does one pouch last?
Most people get hours of comfort from a single pouch — far longer than a spray or lozenge that fades in minutes. Many reviewers keep one in for 2–3 hours.
Is it safe to use every day?
Yes. Rheo™ is sugar-free, alcohol-free, nicotine-free and made in an FDA-registered facility. It’s designed for daily, long-term use. It is not a medical treatment and doesn’t replace professional dental or medical care.
Will it damage my teeth?
The opposite — it’s formulated with xylitol and nano-hydroxyapatite to help protect enamel and support a healthier mouth while it hydrates.
Can I use my HSA or FSA?
Yes. Rheo™ is HSA/FSA eligible — just select the option at checkout.
