Around 2.5 million people across the UK could be using weight-loss medications to manage their weight, according to Jason Murphy, Head of Pharmacy and Superintendent Pharmacist at Chemist4U. Until recent months, these treatments had only been available in the form of injections. The emergence of weight-loss pills has left many wondering which option may be best for them.
Both forms of medication work in the same way, mimicking the GLP-1 hormone that naturally occurs in the body to reduce appetite and slow the rate at which food leaves the stomach. Both support clinically proven weight management when used alongside a reduced-calorie diet and increased physical activity.
Eligibility
Eligibility is broadly similar for pills and injections. They are recommended for adults living with obesity who meet certain BMI criteria or have weight-related co-morbidities. However, there are a number of reasons that either option might not be suitable. If you are pregnant, trying to become pregnant, or breastfeeding, you are not eligible. The same applies if you have certain medical conditions or a family history of them, such as certain thyroid cancers, multiple endocrine neoplasia type 2 (MEN2), gastrointestinal disorders, or gallbladder disease. It is crucial to speak to a regulated provider if you are considering weight-loss medication, as they can assess your eligibility safely and recommend the most suitable course of treatment.
Daily pills or weekly injections
The choice between injections and pills largely comes down to personal preference and suitability. Weight-loss injections such as Wegovy and Mounjaro are taken weekly, while weight-loss pills are taken daily. Those who regularly take daily medicines may find pills more convenient, while others may find it easier to remember an injection once a week. This will vary from patient to patient, so it is worth discussing with a prescriber which option is more compatible with your daily life.
Needle phobia
One major reason people choose pills over injections is needle phobia. Chemist4U’s research found that anxiety around injections is high among adults, with 13% of people who had considered GLP-1s previously deciding against them for this reason. The newer option of an oral alternative has already widened access for people who were uncomfortable or unable to inject themselves but would still benefit from weight-loss medication.
Travel and storage
For frequent travellers, pills may also be the better option. Unlike injections, they do not require refrigeration or sharps bins for disposal, making them potentially more convenient for those travelling regularly for work or holidays.
Fasting
Timing is another key difference. Weight-loss pills are recommended to be taken every morning on an empty stomach after a fast of at least eight hours, with no eating or drinking for a further 30 minutes afterwards. Injections carry no such restrictions.
Private providers across the UK now offer both options following the recent availability of oral treatments, though access through the NHS remains limited for many patients. Regulated consultations remain essential to ensure these medications are used safely and appropriately by those managing obesity or related health conditions.
