If you smoke cigarettes, using combined oral contraceptives (COCs) like Tri-Vylibra Lo raises your risk for serious health problems, such as strokes, heart attacks, and blood clots.

Though rare, Tri-Vylibra Lo can cause liver problems, such as liver damage and liver tumors. These problems are linked more with earlier formulations of COCs that contained higher levels of estrogen (50 mcg or higher), and less so with Tri-Vylibra Lo since it only contains 25 mcg of estrogen.

Tri-Vylibra Lo can raise your levels of blood sugar and triglycerides (a type of fat). If you've been diagnosed with prediabetes or diabetes, your risk of having your blood sugar rise is much higher. This is because Tri-Vylibra Lo can prevent your body from breaking down sugar efficiently. Additionally, this medication can also affect your level of triglycerides. High triglycerides might lead to a higher risk of pancreatitis (pancreas inflammation). Speak with your prescriber before starting Tri-Vylibra Lo if you have a history of high blood sugar or triglycerides. They might help you choose another birth control or monitor your blood work more closely if you take this medication.

Tri-Vylibra Lo and other COCs can raise your blood pressure. Your prescriber might ask you to check your blood pressure regularly.

If you have uncontrolled high blood pressure, Tri-Vylibra Lo might not be the best option for you.

Headaches are a common side effect of COCs like Tri-Vylibra Lo. But, if you experience a new migraine, a migraine that's worse than normal, or a new headache that keeps coming back or is severe, call your prescriber so you can be checked out.

Breakthrough bleeding and spotting are common side effects of hormonal birth control pills. This is more common during the first 3 months of using Tri-Vylibra Lo. Let your prescriber know if you experience any vaginal bleeding outside of your period, or if your period has stopped completely. There are other causes besides your birth control pills for irregular bleeding that your healthcare professional will evaluate.

Let your care team know if you experience symptoms of depression or worsening depression while taking Tri-Vylibra Lo. In cases of serious depression, your prescriber might have you stop taking it.

Certain medications can make Tri-Vylibra Lo get broken down faster in your body, making it work less well to prevent pregnancy. Some examples include carbamazepine (Tegretol) and phenytoin (Dilantin). Use a back-up method or other form of birth control for at least 28 days after stopping any of these medications. Other medications can raise the amount of Tri-Vylibra Lo in your body, which can lead to more side effects. Make sure to tell your prescriber or pharmacist all of your medications so they can make sure they don't interact with Tri-Vylibra Lo.
