Orlistat vs Xenical: Making Your Purchase Decision
Period Effects: Orlistat vs Xenical Comparison
Both orlistat 120mg and Xenical 120mg contain the same active ingredient at identical doses, meaning their potential effects on menstrual cycles are the same. Irregular menstruation is listed as an uncommon side effect, potentially affecting up to 1 in 100 women taking either formulation. The mechanism behind this potential effect isn't fully understood, but may relate to changes in fat-soluble vitamin absorption or weight loss itself.
If you experience menstrual irregularities while taking either orlistat or Xenical, discuss this with your prescriber. The choice between generic orlistat and branded Xenical won't influence period-related side effects, as both contain orlistat 120mg working identically in your body.
Price Comparison: Why Choose Orlistat Over Xenical?
Generic orlistat 120mg offers substantial savings compared to branded Xenical. A 4-week supply (84 capsules) costs £32.99 for orlistat versus £42.99 for Xenical - saving you £10 per month. With discount code EDM10, orlistat costs just £29.69 compared to Xenical at £38.69, maintaining the £9 monthly saving.
For 12-week supplies, the savings become even more significant: orlistat at £86.39 with EDM10 versus Xenical at £116.09 with EDM10 - that's nearly £30 saved over three months. Both formulations work by blocking approximately one third of dietary fat absorption through identical lipase inhibition mechanisms.
Clinical Effectiveness: No Difference Between Versions
Both generic orlistat and branded Xenical deliver the same clinical outcomes when used alongside a reduced-calorie, lower-fat diet. Each 120mg capsule blocks approximately one third of dietary fat from absorption, with unabsorbed fat passing naturally through your digestive system. Side effect profiles are identical, including potential effects on menstrual regularity.
The prescribing criteria remain the same for both options: adults with BMI 30 or above, or BMI 28 or above with weight-related health conditions such as type 2 diabetes or high blood pressure. Your prescriber will determine suitability through individual clinical assessment regardless of which formulation you prefer.
Alternative Option: Alli 60mg
For those seeking a lower-strength option, Alli 60mg provides half the dose of prescription-strength orlistat. At £26.09 for a 4-week supply with EDM10, Alli offers a gentler introduction to orlistat therapy with typically milder gastrointestinal side effects. However, the clinical effect on fat absorption is proportionally reduced compared to the 120mg prescription formulations.
