GLP-1 Medications (Ozempic, Wegovy, Mounjaro): What Mississippi Patients Need to Know Before Starting

What a GLP-1 is and how it works

GLP-1 stands for glucagon like peptide 1, a hormone your body naturally produces in response to eating. It tells the pancreas to release insulin, tells the liver to reduce glucose output, slows stomach emptying, and reduces appetite. GLP-1 receptor agonist medications are synthetic versions designed to act like that natural hormone but last much longer in the body, typically a week per injection.

Tirzepatide is technically a dual agonist, acting on both GLP-1 and GIP receptors, which appears to produce slightly more weight loss in clinical trials.

The products on the market

The category includes several products with overlapping but distinct indications. Naming gets confusing because the same molecule is sold under different brand names for different indications.

Who is a candidate

GLP-1 medications are not for everyone. The standard candidates include adults with type 2 diabetes whose A1C is not at goal on metformin alone, adults with obesity (BMI 30 or higher) or overweight (BMI 27 or higher) with at least one weight related condition, and increasingly, patients with cardiovascular disease, heart failure, or chronic kidney disease whose providers want the protective benefit.

The decision is clinical, made by your prescriber. If your physician has suggested one and you are wondering whether it is worth pursuing, the conversation worth having is with the pharmacist who will fill it, ideally before the first injection.

What to expect in the first 12 weeks

GLP-1 medications are dose titrated. You start at a low dose for a month, increase, and continue stepwise increases over several months until you reach the maintenance dose appropriate for your indication. Trying to start at maintenance dose is the most common mistake patients make and almost always leads to GI side effects severe enough to stop the medication.

Week by week, the typical pattern looks like this:

• Weeks 1 to 4: Starting dose. Mild nausea, occasional reflux, slight loss of appetite. Most patients tolerate this stage well.
• Weeks 5 to 8: First dose increase. Side effects often return briefly. Most resolve within 5 to 10 days as the body adjusts.
• Weeks 9 to 12: Second dose increase for some patients. Appetite reduction becomes more noticeable. Most patients have seen the scale move by this point.
• Months 3 to 6: Continued titration toward maintenance dose. Weight loss and A1C reduction accelerate for most patients.
• Beyond 6 months: Maintenance dose, sustained changes for most patients who stay on the medication and continue the behavioral support.

Managing the side effects

• Eat smaller, more frequent meals rather than three large ones.
• Stop eating at the first sign of fullness. Pushing past it almost always produces nausea or reflux.
• Avoid greasy, fried, or very heavy meals during the first weeks of each dose increase.
• Stay well hydrated. Mild dehydration significantly worsens GI side effects.
• If nausea persists, talk to your pharmacist or prescriber about anti nausea medication for the titration period.
• Slow constipation can usually be managed with adequate fiber and water before adding a stool softener.

Interactions and contraindications

GLP-1 medications slow stomach emptying. That can affect the absorption of certain oral medications, particularly those that depend on rapid absorption. If you take time sensitive oral medications, this is worth reviewing with a pharmacist. Patients with a personal or family history of medullary thyroid carcinoma or MEN2 should not take this class. Patients with a history of pancreatitis are usually advised against it. Pregnant patients should not be on these medications.

The supply and source issue

These medications have been in periodic shortage since 2022. Compounded versions have proliferated outside legitimate pharmacy channels, often at lower prices. I would be careful.

FDA has warned about safety issues with compounded versions sourced from unregistered facilities. Dosing errors, contamination, and counterfeit products have all been reported. The legitimate compounded supply, manufactured by FDA registered facilities under physician prescriptions, is more carefully controlled. The supply you might encounter through a social media ad, a wellness clinic with no pharmacy oversight, or an online retailer offering surprisingly low prices is the source I would not trust.

Nutrient considerations during GLP-1 therapy

Patients on GLP-1 medications often eat significantly less, which is the point. The risk is that protein intake, micronutrient intake, and electrolyte balance can drift below where they need to be. Patients losing weight rapidly can also lose muscle mass alongside fat if protein and resistance training are not part of the plan.

Pharmacist supervised nutrition support during GLP-1 therapy is one of the more useful adjuncts. The Fairview Wellness+ line carries pharmacist selected protein support, B vitamin support, and electrolyte options designed for this exact situation.

When to call a pharmacist

• You are about to start your first GLP-1 prescription.
• You are at a dose titration step and the side effects are worse than expected.
• You take other prescription medications and want to confirm there are no interactions.
• You are considering a compounded GLP-1 product from any source and want a professional opinion.
• You have run out and your refill is delayed due to a shortage.
• You have lost a significant amount of weight and are uncertain whether your other medication doses still fit.
