Some side effects of Promensil include stomach upset, nausea, headaches and muscle pain. This natural supplement designed specifically to address the common symptoms experienced by menopausal and post-menopausal women can be safe when taken as recommended. However, there can be rare side effects associated with Promensil, such as breast tenderness, increase in weight and hives, notes WebMD.
In some cases, this supplement can also cause an allergic reaction. The allergic reaction may be triggered by sensitivity to the ingredients found in Promensil, such as red clover. Promensil contains isoflavones extracted from red clover, calcium and vitamin D3. Another possible side effect is vaginal bleeding, as stated by Consumer Health Digest.
The method in which Promensil works is that it contains red clover isoflavones, which are phytoestrogens or plant-based estrogen. Because there is a decrease in estrogen levels during menopause, many women can experience troublesome symptoms, such as hot flashes and night sweats. Unlike hormone replacement therapy, Promensil is a natural supplement alternative that may help with these symptoms, but this clam has not been proven by clinical research studies.
However, the red clover extract in Promensil also can have certain contraindications, precautions and interactions. For example, women with breast cancer or different types of gynecologic cancer should not take this supplement. Similarly, pregnant or lactating women should also avoid the use of this product. The product is solely intended for menopausal women, as stated by Consumer Health Digest. Because there may be interactions between this supplement and certain prescribed medications, it is advisable to speak with a doctor before using this supplement.
