What is Symlin for weight loss?

Symlin (pramlintide) is a medication used to help manage type 1 and type 2 diabetes in people already using insulin therapy. It received U.S. Food and Drug Administration (FDA) approval in March 2005. Symlin is the brand name. A version of generic pramlintide isn’t available. 


Symlin is in a class of medications called amylin analogs. Amylin is a natural hormone produced by your pancreas. It helps regulate blood glucose levels. As an amylin analog, Symlin mimics how amylin acts in your body. 


Symlin is a prescription medication. It’s available as an injection called SymlinPen that comes in a pre-filled, disposable pen-injector device. You inject yourself with the SymlinPen immediately before eating a meal. Your provider determines the best dose for your injection based on your individual needs and how you tolerate Symlin. 


While not approved for weight loss, some providers prescribe Symlin off-label because it can lead to weight loss.

How does Symlin for weight loss work?

Symlin is a synthetic version of amylin, a hormone naturally produced by your pancreas. Amylin helps reduce food intake, slow gastric (stomach) emptying, and decrease blood sugar levels. 


When your stomach empties more slowly, you may feel fuller longer, which can lead to decreased appetite and reduced calorie intake. Though Symlin is approved for diabetes management, some people experience weight loss as a secondary benefit. 


The starting dose of Symlin depends on your diagnosis and individual needs. People with type 1 diabetes typically start with a dose of 15 micrograms before a meal and a 50% reduction in mealtime insulin dose. As you adjust to the medication, your provider may increase your dose in increments of 15 micrograms up to 60 micrograms. If you have type 2 diabetes, your starting dose may be 60 micrograms before a meal combined with a 50% reduction in mealtime insulin if applicable. The dose can be increased to up to 120 micrograms as needed. 


In a clinical trial where 88% of participants titrated up to higher doses like 240 or 360 micrograms per milliliter, 31% of people taking Symlin lost greater than 5% of their body weight in 16 weeks.

Who can take Symlin for weight loss?

Symlin is FDA-approved to control blood glucose levels in adults with type 1 and type 2 diabetes already using insulin therapy at mealtime. It’s not approved for weight loss but may be prescribed off-label to help treat obesity if a provider feels it’s medically necessary for someone. Symlin can support weight loss and management by decreasing appetite and increasing satiety.

Symlin weight loss dosages and how to use it

Symlin is an injection available in 15-, 30-, 45, or 60 microgram doses. People with type 1 diabetes start with 15 micrograms and gradually increase their dose. Individuals with type 2 diabetes who also take mealtime insulin start at 60 micrograms and increase to 120 micrograms after 3 days if they tolerate the medication without significant nausea. 


You inject yourself subcutaneously (under the skin) in your stomach or thigh before each major meal of the day. Injecting Symlin in your arm isn’t recommended because it may absorb better in your thigh or abdomen. Make sure it’s at room temperature before you inject it and take each injection immediately before eating a full meal. 


For weight loss, your provider will likely start you on a lower dose and monitor side effects and how your body adjusts to the medication before increasing your dose. 


Symlin shouldn’t be mixed with an insulin dose. Instead, take it as a separate injection from insulin. And don’t inject insulin and Symlin at the same site. Injection Symlin and insulin at sites at least 2 inches from each other.


If you miss a dose of Symlin, wait until your next dose and take only the prescribed amount.

Symlin side effects and warnings

If you have side effects from Symlin for weight loss or its FDA-approved use, you’ll most likely have hypoglycemia (severe low blood sugar), lightheadedness, dizziness, shakiness, sweating, hunger, rapid heartbeat, confusion or trouble concentrating, changes in vision, headache, irritability, or drowsiness. 


You’re more likely to have hypoglycemia if you take more Symlin or insulin than prescribed, change doses without checking your blood sugar, eat a smaller meal than usual, have a low blood sugar level before eating, or drink alcohol. 


The most common adverse reactions for Symlin include nausea, vomiting, headache, dizziness, fatigue, and anorexia. 


Before taking Symlin, you should know that it can interact with other medications like insulin, drugs that affect how food is digested, absorbed, moves through your body, or eliminated, like atropine, or medications that affect glucose metabolism, like antidepressants, such as Prozac (fluoxetine) or monoamine oxidase inhibitors (MAOIs). 


Though Symlin can lead to common or serious side effects, there are benefits. It can help with glucose control, slow gastric emptying, and keep you feeling fuller longer. These benefits can lead to a loss of at least 5% of your body weight in 16 weeks. 


If you take Symlin and have any side effects, work with your provider and consider reporting negative side effects to the FDA by visiting MedWatch or calling 1-800-FDA-1088.

What does Symlin cost for weight loss?

Symlin is pricey. The price for SymlinPen 60, which contains 1,000 micrograms per milliliter, is $1,100.31 for 3 milliliters, according to drugs.com with its discount. SymlinPen 120 contains 1,000 micrograms per milliliter and costs $1,304.86 for 5.4 milliliters with the drugs.com discount. These are the costs you’ll pay before insurance. 

If you have insurance that covers Symlin, your provider will need to submit a prior authorization request explaining that the medication is medically necessary for you. If approved by your insurance, they may cover some or all of the cost of the medication depending on your plan. Insurance is more likely to cover Symlin for the treatment of diabetes. It’s less likely to approve the prior authorization for weight loss. 

There’s no less costly generic version of Symlin available today.

To find drug discount cards and save money on medication with or without insurance, visit sites like drugs.com, GoodRx, WellRx, NeedyMeds, or SingleCare Rx.

How does Symlin compare to other weight-loss medications?

You may lose weight as a secondary benefit when using Symlin, which isn’t approved for weight loss. Other types of medications approved for or used off-label for weight loss include glucagon-like peptide-1 (GLP-1) medications, like Ozempic (semaglutide) or Wegovy (semaglutide), a GLP‐1/GIP (gastric inhibitory polypeptide) medication like Zepbound (tirzepatide) or Mounjaro (tirzepatide), or an opioid antagonist medication like Contrave (bupropion HCI/naltrexone HCI). 


Wegovy and Zepbound are approved for weight management in people with obesity or who are overweight and have at least one weight-related condition. They are often most effective when coupled with a reduced-calorie diet and an increase in physical activity. Contrave is approved for weight loss and management in people who are overweight or obese. Ozempic and Mounjaro are approved to help control blood sugar in people with type 2 diabetes. 


Symlin for weight loss may lead to a loss of at least 5% of your body weight in 16 weeks, likely when taken at higher doses. With Wegovy, people lost up to 14.9% of their body weight in 68 weeks. In 72 weeks, someone taking Zebpound may lose up to 20.9% of their body weight. Where people taking Contrave can lose 5 to 10% of their body weight in 56 weeks. 


Common side effects of these medications are similar and include nausea, vomiting, diarrhea, headache, and decreased appetite. But, each medication has benefits. Symlin, Ozempic, Zepbound, and Contrave can all lead to weight loss. Symlin, Ozempic, and Zepbound can help manage blood sugar. Ozempic, Wegovy, and Zepbound may reduce the risk of cardiovascular problems. And Contrave helps reduce food cravings and can reduce appetite. Knowing how these medications compare can help you and your provider decide which is medically appropriate for you. 


The best way to find out which weight loss medication, if any, is best for you is to talk to a weight loss provider.
