Repatha is a brand-name injection doctors may prescribe to treat certain types of high cholesterol in adults and some children. It may also be prescribed to reduce the risk of heart attack, stroke, and the need for heart surgeries in adults. However, the idea of administering an injectable medication can sometimes feel intimidating. That’s why many people turn to social media platforms, such as Reddit, to read what the experience is like for other people using Repatha.

In this article, we’ll look at answers to some of the most common questions sourced from real Repatha users, and compare them to our medically-reviewed answers to help you prepare for your first dose.

It depends. In some cases, such as if you have a certain type of high cholesterol, your insurance may cover your Repatha prescriptions from the start. Repatha is prescribed to reduce low-density lipoprotein (LDL) cholesterol (or “bad cholesterol”) in the following people:

Your doctor may also prescribe Repatha to reduce the risk of certain cardiovascular events, including heart attack, stroke, and unstable angina.

In other cases, your doctor may prescribe a different medication first, such as a statin, to treat your condition. Statin drugs are often a first-line treatment for people with high cholesterol and are generally a less expensive option than Repatha injections.

But if statins alone don’t work to manage your condition or you are unable to tolerate the side effects, your doctor may switch you to Repatha or add it to your current treatment regimen.

Note: Your insurance may require prior authorization before it will cover the cost of Repatha.

In Repatha’s clinical trials, people taking Repatha did not report weight loss as a side effect. However, a subreddit of the drug suggests some Repatha users may have a different experience.

Gastrointestinal (GI) side effects are possible with Repatha use and may include gastroenteritis and nausea, vomiting, and diarrhea. These GI side effects may contribute to a loss of appetite and dehyrdation—both of which can contribute to weight loss.

If you concerned about weight loss, talk with your doctor. They can look for potential causes and suggest ways to maintain your weight.

At the 3-month mark, you can expect to see a significant reduction in your LDL cholesterol.

Based on Repatha’s clinical trials, people taking the drug for 3 months experienced a substantial decrease in LDL cholesterol. The effects of the drug varied depending on the condition the drug was being used to treat and whether study participants took Repatha alone or in combination with other medications.

“Combining a balanced diet and exercise with your cholesterol-lowering medication can actually help improve your overall cholesterol levels. In fact, participating in physical activity, such as brisk walking or cycling, can increase your high-density lipoprotein (HDL) cholesterol levels (good cholesterol).”

Typically, Repatha is a long-term treatment. But if you have questions about what to expect while using it, talk with your doctor.

It’s possible. One person’s response to a drug may be different than someone else’s. Some people may have no side effects, while others may experience mild or serious ones.

Although it is not possible to predict which side effects (if any) you may encounter, some of the most common ones reported in Repatha’s clinical trials include:

If you have questions about any of Repatha’s side effects, speak with your doctor or pharmacist.

Because one person’s experience with Repatha may differ from another, it’s helpful to weigh clinical data against real-world experiences regarding insurance hurdles, potential weight changes, and common side effects, such as nausea and vomiting or back pain. Most people see a significant drop in their cholesterol levels within the first three months of treatment.
