Diet pills, also known as appetite suppressants, are weight-loss medications for people with obesity. They work by lessening your appetite or making you feel full faster. While they can be effective, they are not a cure-all and should be used in conjunction with a reduced-calorie diet and regular exercise. Prescription diet pills can be addictive and are typically recommended for short-term use. They can also cause side effects such as drowsiness and dependence. To avoid these side effects, it is important to take precautions such as maintaining healthy sleep habits, limiting over-the-counter drugs that cause drowsiness, and consulting a doctor or pharmacist.

What You'll Learn
Natural sleep aids like melatonin and valerian supplements
Melatonin
Melatonin is a natural hormone produced by the brain in response to darkness, helping regulate your body's internal clock or circadian rhythm. When your body does not produce enough melatonin, your sleep can be disrupted, and you may have trouble falling or staying asleep. In such cases, melatonin supplements, a synthetic form of the hormone, may help. They are widely available over the counter and can help adjust sleep timing in people with jet lag, shift work disorder, or a delayed sleep phase.
It is important to note that melatonin supplements are not heavily regulated, and dosages can vary significantly, especially in chewable forms. The recommended dosage is generally between one to five milligrams, taken 30 minutes before bedtime. It is also advised to start with the lowest dose and gradually increase it if needed, without exceeding the recommended amount. Melatonin is fast-acting and can make you feel sleepy within 20 to 40 minutes, lasting for about five hours.
Valerian
Valerian is an herb commonly used as a sleep aid and is available in various commercial preparations. It is considered safe for use, with few reported side effects. However, the evidence supporting its effectiveness as a sleep aid is inconclusive. Most studies have found no significant difference between valerian and a placebo in improving sleep quality, even in individuals with insomnia.
While natural sleep aids like melatonin and valerian supplements may be helpful in certain cases, it is always advisable to consult a healthcare professional before taking any supplements, especially if you are pregnant, breastfeeding, or taking other medications.

Prescription vs. over-the-counter (OTC) diet pills
There are two types of diet pills: prescription weight-loss pills and over-the-counter (OTC) weight-loss pills. Prescription weight-loss pills are medications you get through your doctor. Over-the-counter weight-loss pills and herbal supplements can be purchased without a prescription and are available in many vitamin shops and drug stores.
Prescription diet pills are stronger than over-the-counter ones. You need a prescription from a healthcare provider to get these pills. Providers don’t typically recommend using prescription sleeping pills long-term because they’re not a cure for insomnia and there’s a risk of dependence and addiction. They may help in some cases, but providers will usually only prescribe them for short-term relief. Prescription appetite suppressants can help with weight loss for people with obesity. They work to lessen your appetite or make you feel full faster. Long-term prescription appetite suppressants are generally safe if you take them as prescribed.
On the other hand, you don’t need a healthcare provider to write you a prescription for an OTC medication. The only over-the-counter weight-loss pill approved by the FDA, Alli, contains a lower dose of Orlistat (60 mg), the same medication in Xenical. It works by reducing the body's absorption of fat. One review of 33 randomized controlled trials involving 9,732 participants reports that Orlistat provides a "slight but significant decrease in body weight." Some OTC appetite suppressants or weight-loss supplements contain ephedra, ephedrine, or caffeine (stimulants). And some have been linked to reports of heart attack, seizure, stroke, and death. It’s important to talk to your healthcare provider first if you’re thinking of taking OTC appetite suppressants or supplements.
Both prescription and OTC weight loss pills have one of three goals: reduce your appetite, making it easier to make healthy food choices; increase your body's ability to burn fat, creating a larger calorie deficit; or inhibit your body's ability to absorb the fat in the foods you eat. Some diet pills are approved by the U.S. Food and Drug Administration (FDA) while others don't require FDA approval.

Side effects and risks of appetite suppressants
Appetite suppressants can cause various side effects and carry certain health risks, especially when not used as directed. While FDA-approved medications are generally safe and effective when taken as prescribed, they can be problematic when used otherwise.
Short-term prescription appetite suppressants, in particular, require more caution due to their potential for severe side effects and addiction. These may include rapid or irregular heartbeat (tachycardia or arrhythmia), mood changes such as depression or anxiety, cognitive alterations like agitation, delirium, or psychosis, nausea, vomiting, diarrhoea or constipation, and abdominal pain. One of the risks associated with short-term appetite suppressants is their misuse or overuse, especially if there is a history of substance abuse.
Long-term prescription appetite suppressants are generally safer when taken as directed. However, they can still carry risks, especially when used for longer than 12 weeks. Additionally, certain over-the-counter (OTC) appetite suppressants or weight-loss supplements may contain stimulants such as ephedra, ephedrine, or caffeine, which have been linked to heart attacks, seizures, strokes, and even death in some cases.
Appetite suppressants are contraindicated for individuals with specific health conditions as they can exacerbate these issues. People with heart disease, uncontrolled high blood pressure, glaucoma, an overactive thyroid (hyperthyroidism), liver disease, or a history of eating disorders should refrain from taking them. Moreover, those taking antidepressants or anti-anxiety medications should also avoid appetite suppressants due to potential drug interactions and an increased risk of suicidal ideation.
It is crucial to consult a healthcare provider before starting any appetite suppressant medication to ensure safe and effective use, considering individual health histories, goals, and potential side effects.

Combining diet pills with other medications
Some dietary supplements can affect how other medications work in the body. For example, St. John's wort, an herbal supplement, can reduce the effectiveness of drugs for HIV/AIDS, heart disease, depression, organ transplants, and birth control pills. Similarly, warfarin (a blood thinner), ginkgo biloba (an herbal supplement), aspirin, and vitamin E can all increase the risk of internal bleeding or stroke when combined.
Foods and beverages can also interfere with the effectiveness of medications. For instance, grapefruit and grapefruit juice can affect the levels of certain prescription and non-prescription drugs in the body, increasing the likelihood of side effects. Alcohol can increase or decrease the effects of medication and may lead to internal bleeding and issues with the liver, heart, and lungs. It is generally recommended to avoid alcohol when taking any medication.
Additionally, certain drug combinations should be avoided due to potential adverse effects. For example, taking a cough medicine (antitussive) and a sleep aid (sedative) together can cause interactions. Combining two or more drugs with the same active ingredient can lead to side effects or an overdose. It is important to be aware of the potential risks and always follow the instructions provided with your medication.
If you are taking diet pills, it is crucial to disclose this information to your healthcare provider and ask about any possible interactions with other medications or supplements you are currently taking. They can advise on the safest course of treatment and help you manage your health effectively.

Addiction and dependence on sleep aids
Sleep aids and pills can be highly addictive, and dependence can develop in as little as a few weeks. While they may seem like a simple solution for insomnia and other sleep issues, they can quickly lead to more problems than anticipated. Sleep aids are widely used, with an estimated 1 in 7 people in the US suffering from long-term insomnia and approximately 1 in 3 people over 65 taking some form of sleep medicine.
The risk of addiction and dependence is a serious concern with sleep aids. Dependence often begins with the intermittent use of sleep aids to treat occasional insomnia, but as use increases, the body develops a reliance on the medication. This can lead to physical and psychological dependence, making it challenging to reduce dosage or stop taking the medication. Withdrawal symptoms can include irritability, tremors, and cramps, as well as worsened insomnia and other sleep issues.
Signs of addiction to sleep aids include a steady increase in dosage, as the amount previously prescribed becomes less effective over time. This is a classic sign of addiction, according to the National Institute on Drug Abuse (NIDA). Older types of sleeping pills, such as benzodiazepines (including Valium and Xanax), are highly addictive, while newer "Z-drugs" like Ambien and Sonata may be less physically addictive but can lead to psychological addiction.
Some individuals may also abuse sleeping pills to experience a high or a sense of euphoria. Other signs of addiction include being unable to stop taking the medication, experiencing negative consequences due to continued use, and avoiding social activities to use sleep aids. It is important to seek help as soon as possible, as addictions can quickly worsen.
To improve sleep without relying on sleep aids, individuals can try establishing healthy sleep habits. This includes reducing caffeine intake, setting regular sleeping times, and eliminating electronic use at least an hour before bedtime. Cognitive behavioral therapy (CBT) is another effective approach to improving sleep without medication.
