SymlinPen
Pramlintide, also known by the brand name SymlinPen, helps lower blood sugar in adults with Type 1 diabetes or Type 2 diabetes when fast-acting or mealtime insulin isn't enough. It's an amylin analog that's given as an injection under the skin before meals. This medication works by slowing down your digestion and preventing the release of a hormone that causes your blood sugar to go up. Though it's used at the same time as your mealtime insulin, it shouldn't be mixed and must be injected separately. Potential side effects include nausea, low appetite, and headache.

How SymlinPen (pramlintide) works
SymlinPen (pramlintide) is an amylin analog. It's a man-made version of human amylin, a natural hormone made in our body. The medication helps to lower blood sugar by:
- Slowing your digestion, which can affect how your body absorbs nutrients
- Blocking a hormone called glucagon, which stops your liver from releasing more sugar
- Making you feel full for longer, which reduces the number of calories your consume

Pharmacist tips for SymlinPen (pramlintide)
- Before using SymlinPen (pramlintide), you should receive training from a healthcare professional on how to use it safely and correctly. If you have any questions, contact your care team.
- Allow your SymlinPen (pramlintide) to come to room temperature before injecting it. This will lessen pain and discomfort from the injection.
- Inject SymlinPen (pramlintide) right before a meal. If you skip the meal, don't take a dose. Instead, wait until your next meal before taking your usual dose.
- Change the site of where you give yourself SymlinPen (pramlintide) injection each time to prevent skin irritation.
- SymlinPen (pramlintide) can affect the way some medications get absorbed into your body. You might need to take certain medications (like birth control pills, antibiotics, or pain medicines) 1 hour before or 2 hours after SymlinPen (pramlintide). Talk with your pharmacist about the best times to take your medications.
- Use a new needle each time you inject SymlinPen (pramlintide) to prevent contamination. Don't share your SymlinPen (pramlintide) with anyone, even if the needle is changed. This can put you and others at risk for infections.
- Never mix SymlinPen (pramlintide) with insulin in the same syringe. They should be given as separate injections, and at least 2 inches away from each other.
- SymlinPen (pramlintide) is almost empty when the tip of the plunger is near the thickest line on the cartridge. Make sure to refill your medication before you run out.
- Store unopened SymlinPen (pramlintide) pens in the refrigerator up until the expiration date. Open pens can be kept at room temperature or in the refrigerator for 30 days.
How to use SymlinPen (pramlintide):
- Check your SymlinPen (pramlintide) to make sure it isn't expired, and pull the cap off. Then, attach a new pen needle.
- If you're using SymlinPen (pramlintide) for the first time, you'll need to prime your pen. To do this, turn the dial to 15 mcg and pull the knob out as far as it'll go. Hold the pen with the needle pointing up and push the knob until it stops. You should see a stream of liquid. If you don’t see the stream, repeat this process up to 6 times.
- Once you're ready to inject, turn the dial to your correct dose. You should see a line, arrow, and number of your dose. If not, you don't have enough medication in your pen.
- Insert the needle into your skin and push the knob in all the way. Hold for 10 seconds, then pull the needle out.
- Replace the needle cover and carefully unscrew the needle from the pen. Place it into a sharps container. Then replace the pen cap.
Common questions about Symlinpen
You can inject Symlinpen under the skin of your stomach area (not within 2 inches of your belly button) or thigh. But be sure to inject it at least 2 inches away from your insulin injection. Make sure to first wipe the area clean with an alcohol swab and let it dry before injecting your dose.
Each Symlinpen carton comes with two multi-dose pen injectors. How many doses each pen will last you depends on your specific dose. SymlinPen 60 can be used if your dose is 15 mcg, 30 mcg, 45 mcg, or 60 mcg. It contains a total of 1,500 mcg in each pen. This means if your dose is 60 mcg and you're using it 3 times a day, each pen will last you about 8 days. SymlinPen 120 can be used if your dose is 60 mcg or 120 mcg. Each pen contains a total of 2,700 mcg. This means if your dose is 120 mcg and you're using it 3 times a day, each pen will last you about 7 days. Follow up with your prescriber to learn how long each Symlinpen pen will last you and when to request a refill from the pharmacy.
No, don't take Symlinpen without insulin. It's only FDA approved as an add-on treatment to your mealtime insulin. This medication doesn't replace your daily insulin, but it might lower how much insulin you need before meals.
Symlinpen isn't FDA-approved as a weight loss medication. But because it can make you feel fuller and reduce the calories your body absorbs from meals, it's possible that you might experience some weight loss. In studies lasting up to 1 year, people taking Symlinpen lost about 2 to 4 lbs of body weight. Speak with your prescriber if you have questions about this medication and weight loss.
No, the pen needles that you need to attach to your Symlinpen aren't included. You'll need to get 29, 30, or 31 gauge pen needles separately.
Yes, you can take Symlinpen with metformin (Glumetza). There aren't any known interactions between these medications. Be sure to attend your follow-up appointments so your prescriber can review how well your diabetes medications are working for you and adjust them as needed.
There isn't a specific amount of times per day that you should take Symlinpen. It should be taken just before each major meal, or one that's at least 250 calories or 30 grams of carbohydrates. Work with your prescriber to plan how often you should be using this medication.
It's not known whether Symlinpen is safe in pregnancy as there haven't been enough studies. But it's typically not a first-choice option to control blood sugar or diabetes during pregnancy. If you are planning to or have become pregnant, speak with your OB-GYN provider about medication options that are best during pregnancy.

Risks and warnings for SymlinPen (pramlintide)
SymlinPen (pramlintide) can cause some serious health issues. This risk may be even higher for certain groups. If this worries you, talk to your doctor or pharmacist about other options.
Low blood sugar
- Risk factors: Taking other diabetes medications that can lower blood sugar | Use more SymlinPen (pramlintide) or insulin than prescribed | Eating less food or smaller meals than normal | More physically active | Drink alcohol
Though SymlinPen (pramlintide) on its own doesn't cause low blood sugar (hypoglycemia), taking it with other diabetes medications (e.g., insulin, sulfonylureas) or drinking alcohol can raise your risk. This usually happens within 2-3 hours after injecting this medication. Your insulin dose will be lowered when you first start using SymlinPen (pramlintide). You might need to check your blood sugar levels more often to avoid this potentially life-threatening side effect. Talk to your prescriber about the symptoms of low blood sugar and how to treat it. Until you know how SymlinPen (pramlintide) affects you, don't drive, use heavy machinery, or participate in dangerous activities.
Injection site reactions
SymlinPen (pramlintide) can cause injection site reactions on the skin. These reactions include redness, swelling, itching, or bruising. They usually go away on their own in a few days to a few weeks. Speak to your prescriber if your symptoms don't go away or if they become bothersome.
Stomach emptying problems
- Risk factors: History of stomach problems | Medications that affect stomach emptying
Because SymlinPen (pramlintide) slows your digestion, it's not recommended if you have stomach emptying problems or are taking medication that can affect how food moves through your gut. Tell your prescriber about all the medications you're currently taking or if you have a history of stomach problems.
Medication interactions
SymlinPen (pramlintide) can interact with other medications. Some medications (e.g., birth control pills, antibiotics, or pain medicines) should be taken 1 hour before you inject SymlinPen (pramlintide) or 2 hours after. It's important to let members of your care team know about all the prescription and non-prescription medications you're taking.
