What to Avoid When Taking Weight Loss Drugs

Avoid Combining with Other Medications

Combining weight loss drugs with other medications can lead to adverse interactions. It's crucial to consult your GP before taking them if you're already on prescribed medication.

Some drug interactions can amplify side effects or decrease the effectiveness of your existing medication. Always keep your healthcare provider informed about any supplements or over-the-counter medicines you're using.

Steer Clear of Alcohol

Alcohol can interfere with how weight loss drugs work in your body. Drinking alcohol while on these medications can increase the risk of experiencing side effects like dizziness or gastrointestinal issues.

Moreover, alcohol is high in calories and may counteract the benefits of your weight loss efforts. It's wise to limit or abstain from alcohol consumption when taking these drugs.

Avoid High Caffeine Intake

High caffeine intake can exacerbate the side effects of weight loss drugs, such as increased heart rate and anxiety. Many weight loss medications already contain stimulants that mimic the effects of caffeine.

Try to limit your intake of caffeinated beverages like coffee, tea, and energy drinks to avoid compounding these effects. Opting for decaffeinated options might be beneficial.

Not Following the Prescription

Ensuring you follow the prescribed dosage and schedule from your healthcare provider is essential. Taking more than recommended will not speed up weight loss and can increase side effects.

Skipping doses or suddenly stopping the medication can lead to withdrawal symptoms or weight rebound. Stick closely to the guidance provided to maintain effectiveness and safety.

Avoid Fatty or Greasy Foods

Many weight loss drugs affect how your body processes dietary fat. Eating high-fat meals can increase the possibility of unpleasant digestive side effects.

Focus on a balanced diet rich in fruits, vegetables, and lean proteins. This approach supports your medication and overall weight loss goals.

Using Expired or Unapproved Drugs

Ensure your medication is in date and acquired from a reputable source. Taking expired or unapproved weight loss drugs may not only be ineffective but also unsafe.

Always consult your healthcare provider before trying any new medication. This includes checking if it's approved by relevant UK health authorities, such as the MHRA.
