You have been taking Acthéane for a few weeks and your scale shows one or two kilos more. The reflex is natural: to suspect the medication. This concern often arises on forums dedicated to menopause, to the point of becoming a persistent misconception. Acthéane is a homeopathic medication marketed by Boiron, used against hot flashes and functional disorders of menopause. Its composition contains no hormones, which radically distinguishes it from hormone replacement therapies.
Acthéane without hormones: why the comparison with hormone therapy doesn’t hold
The confusion comes from a common shortcut. Many women associate any treatment related to menopause with hormones. Hormone replacement therapies (HRT) act on estrogens and progestins. Their impact on metabolism and fat distribution is documented.

Acthéane does not work in this way at all. Its homeopathic formula contains no hormonal substances of the estrogen or progestin type. Applying the same fears to Acthéane as to an HRT amounts to comparing two products that have nothing in common pharmacologically.
To delve deeper into the link between Acthéane and weight, it is essential to first establish this fact: no hormonal mechanism in this medication can explain a modification of lipid or carbohydrate metabolism.

Official Acthéane leaflet and side effects: what the reference sources say
The leaflet published by the ANSM (National Agency for the Safety of Medicines) and the Vidal sheet for Acthéane do not mention weight gain among the side effects. Boiron’s website does not either.
You may be wondering if the absence of mention means a total absence of risk? In pharmacovigilance, a side effect is included in a leaflet only when a sufficient statistical signal is detected. No pharmacovigilance signal related to weight gain has been reported for Acthéane in the publicly accessible databases.
The warnings in the leaflet concern other points:
- Intolerance to fructose, galactose, or a lactase deficiency of Lapp, due to the excipients (sugars) present in the tablets.
- The necessity to consult a doctor if no improvement is observed after three months of treatment.
- The requirement to take it away from meals, with no link to any metabolic effect.
In summary, neither health authorities, nor the manufacturing laboratory, nor the French drug databases associate Acthéane with a variation in weight.
Menopause and weight gain: the real factor behind the scale
The period during which women take Acthéane coincides with menopause, a phase of major physiological upheavals. This is where the key to the misunderstanding lies.
During menopause, the drop in estrogens alters the distribution of body fat. The basal metabolism slows down. The weight gain observed is related to menopause itself, not to the symptomatic treatment used against hot flashes.
Several mechanisms accumulate during this period:
- The decrease in muscle mass, which reduces energy expenditure at rest.
- Changes in sleep (night awakenings, sweats), which disrupt appetite regulation.
- Stress and chronic fatigue, which promote abdominal storage and compensatory eating behaviors.
- An often involuntary reduction in physical activity, related to the frequent joint pain during this period.
Attributing these kilos to Acthéane is to confuse temporal coincidence with a cause-and-effect relationship. The medication is taken during menopause, weight gain occurs during menopause, but the former is not responsible for the latter.
Medications that cause weight gain: how to distinguish a true weight effect
Some medications do indeed cause weight gain. This is the case for several families of psychotropics (certain antidepressants, antipsychotics), long-term corticosteroids, or hormonal treatments containing estrogens or synthetic progestins. These medications act on identified metabolic or hormonal receptors.
For a medication to cause weight gain, it generally must meet at least one of these conditions: modify appetite via neurotransmitters (serotonin, dopamine, histamine), disrupt carbohydrate or lipid metabolism, or promote water retention through hormonal action.
Acthéane, as a homeopathic preparation, does not present any of these mechanisms of action. Its homeopathic dilution implies an extremely low concentration of active ingredient, with no known interaction with the metabolic pathways involved in weight regulation.
A useful reflex in the face of any weight concern
If you notice weight gain during treatment, discuss it with your doctor or pharmacist. Mention all the medications you are taking, including dietary supplements. A comprehensive assessment allows for identifying the true cause rather than discontinuing a potentially useful treatment based on unfounded suspicion.
Stopping Acthéane out of fear of an undocumented weight effect could deprive you of relief from hot flashes, without any benefit on the scale. The problem would then be twofold: untreated menopause symptoms and continued weight gain, since the cause lies elsewhere.
Weight gain during menopause is a physiological phenomenon, not a side effect of Acthéane. No official data links this homeopathic medication to a variation in weight. Searching for the cause in the treatment diverts attention from the real levers of action: adapted physical activity, diet adjusted to new metabolic needs, and regular medical follow-up.
