How to ease nausea and stomach side effects
- Eat smaller meals, slowly, and stop as soon as you feel full
- Go easy on greasy, fried, very sweet or spicy foods
- Don’t lie down right after eating
- Sip water through the day, and add fiber slowly if you’re constipated
- Eat protein at each meal, even when you’re not hungry
- Tell your provider early. They can hold your dose or step up more slowly.
The American Association of Clinical Endocrinology also advises enough fluids, adding fiber gradually, and enough protein to protect your muscle.

How long do side effects last?
They’re usually strongest in the first days after you start or raise your dose, and ease over the next few weeks as your body adjusts. If a side effect doesn’t ease, or keeps you from eating or drinking, call us. You don’t have to push through.

Vision: In November 2026 the FDA required a warning for GLP-1 medicines about a rare eye condition, NAION, that can cause sudden vision loss in one eye. The risk appears very low. Sudden vision loss needs emergency care immediately. Report new blurred vision or other sudden vision changes to a healthcare professional right away.
Mood: In January 2026 the FDA removed the warning about suicidal thoughts from GLP-1 weight loss labels after finding no increased risk. If your mood changes, tell your provider anyway.

Surgery or sedation: These medicines slow your stomach. Tell anyone doing a procedure with anesthesia or sedation that you take one. Guidance from surgery and anesthesia groups says most people can keep taking it, often with a liquid diet the day before.

Cost and insurance
What you pay each month
Your visits and your medicine are priced separately, so you only pay for what your insurance doesn’t cover.
| Your situation | Visits and labs | Medicine | Each month |
|---|---|---|---|
| Self-pay program, individually prescribed compounded dose 2.5–7.5 mg | $99 | $199 | $298 |
| Self-pay program, individually prescribed compounded dose 10–15 mg | $99 | $299 | $398 |
| Insurance covers your medicine | Your plan-dependent cost | Your plan-dependent pharmacy cost | Your plan-dependent cost |
| Insurance does not cover medicine; compounded treatment individually prescribed if appropriate | Your plan-dependent cost | $199 or $299 | Your plan-dependent visit/lab cost plus eligible prescribed medicine |
- $99 a month, no insurance needed: a visit with your provider every month and lab work every 3 months. Self-pay patients can sign up for this program.
- With insurance: we bill your plan for your visits and labs. Your cost depends on your plan, including copay, coinsurance and deductible.
- If your plan covers tirzepatide (Zepbound or Mounjaro): we send your prescription to your pharmacy, and your out-of-pocket cost depends on your plan. Many plans need prior approval first, and we help with the paperwork.
- If prescribed for your individual medical need: compounded tirzepatide is $199 a month at 2.5, 5 or 7.5 mg, or $299 a month at 10, 12.5 or 15 mg. Compounded medicine is considered only when an individual medical need cannot be met by an FDA-approved drug and applicable requirements permit it. Cost or lack of insurance coverage alone does not determine eligibility. Your provider determines your dose and follow-up plan.
Compounded tirzepatide is not FDA-approved. The FDA does not review compounded medicines for safety, effectiveness or quality. Your provider talks with you about whether it’s right for you. Prices as of November 2026. HSA and FSA cards are accepted. Compounded medicine is considered only when an individual medical need cannot be met by an FDA-approved drug and applicable requirements permit it. Cost or lack of insurance coverage alone does not determine eligibility.
