Are you an adult who has serious health issues as a result of your weight? Have you tried diet and exercise but still haven’t lost enough weight? If you answered yes to any of these questions, you may be a candidate for a prescription weight-loss medication.
Prescription drugs are medications that your doctor has prescribed for you. They cannot be purchased off the shelf in a drug store, as nonprescription medications can.
Just remember that you should use prescription weight-loss medications in addition to, not instead of, a healthy diet and exercise.
Who may use weight-loss medications?
In some circumstances, your doctor could advise you to use a medicine for weight loss. They consist of the following if you haven’t been successful in losing weight despite diet and exercise:
- BMI (body mass index) is more than 30. This indicates that you have obesity, a condition marked by an excess of body fat.
- More than 27 BMI. You also suffer from an obesity-related significant medical condition, such as diabetes or high blood pressure.
Your doctor considers your medical history and current health issues before selecting a medication for you. Then your doctor discusses the advantages and disadvantages of prescription weight-loss medications with you.
Not everyone should use these medications. For instance, if you’re attempting to get pregnant, are pregnant, or are nursing, you shouldn’t take prescription weight-loss medications.

What medications have been approved for weight loss?
The Food and Drug Administration (FDA) has approved six weight-loss drugs for long-term use:
- Bupropion-naltrexone (Contrave)
- Liraglutide (Saxenda)
- Orlistat (Xenical, Alli)
- Phentermine-topiramate (Qsymia)
- Semaglutide (Wegovy)
- Setmelanotide (Imcivree)
The majority of prescription weight-loss medications work by making you feel less hungry or fuller. Some people do both. The exception is orlistat. It has an impact on how your body absorbs fat.
A combination drug is bupropion-naltrexone. Naltrexone is used to treat alcohol and opioid addiction. Bupropion is both an antidepressant and a quit-smoking aid, which is a drug that helps people quit smoking. Bupropion, like all antidepressants, comes with a warning about the risk of suicide. Bupropion-naltrexone can cause an increase in blood pressure. As a result, at the start of treatment, your provider will need to check your blood pressure on a regular basis. Nausea, headache, and constipation are all common side effects.
Liraglutide is also used to treat diabetes. It is administered on a daily basis. A common complaint is nausea. Its use may be limited if you vomit.
Orlistat can also be obtained without a prescription in a reduced-strength form (Alli). Side effects of orlistat include passing gas and having loose stools. When taking this medication, you must eat a low-fat diet. In rare cases, people have had serious liver injury with orlistat. However, researchers have not discovered that the drug causes liver damage.
Phentermine-topiramate is a combination of phentermine, a weight-loss medication, and topiramate, an anticonvulsant. Because it acts like a stimulant drug called an amphetamine, phentermine has the potential to be abused. An increase in heart rate and blood pressure, as well as insomnia, constipation, and nervousness, are all possible side effects. Topiramate raises the likelihood of birth defects.
Phentermine (Adipex-P, Lomaira) is also used to lose weight on its own. It’s one of four similar weight-loss drugs that have been approved for use for less than 12 weeks, a term known as short-term use. The other drugs in this class are rarely prescribed.
Semaglutide is also used to help manage type 2 diabetes. You take it as a weekly shot to manage obesity.
It can have the following side effects:
- Vomiting and nausea
- Pain in the abdomen
The FDA has only approved setmelanotide for people aged 6 and up who are obese due to one of the following rare inherited conditions:
- Deficiency of pro-opiomelanocortin
- Type 1 proprotein subtilisin-kexin deficiency
- Lack of leptin receptors
To use the medication, you must have test results proving that you have one of these conditions. Setmelanotide does not address any of the genetic issues that contribute to these conditions. But it can help you lose weight. It has the ability to suppress your appetite and make you feel fuller. It may also assist you in burning calories while your body is at rest.
Setmelanotide is administered to you on a daily basis. It can have the following side effects:
- Skin that is swollen or irritated where the needle was inserted
- Darker skin patches
- Pain in the abdomen
- Unwanted sexual responses
- Suicidal ideation
Setmelanotide should never be given to a child under the age of six. It can cause dangerous reactions in newborns and babies.
Drugs for weight loss are not a simple solution. But they might assist you in implementing the lifestyle modifications you need to make in order to reduce your weight and enhance your health.
