Antistax tablets contain a dry extract of red vine leaves and are used for the treatment of mild forms of chronic venous insufficiency, such as swollen legs, varicose veins, heaviness or pain in the legs[1].
Common side effects reported with Antistax tablets include:
- Hypersensitivity reactions of the skin, such as itching, reddening, hives, and generalized pruritic rash[3][5].
- Gastrointestinal symptoms such as stomach upset, nausea, constipation, or general stomach discomfort[3][5].
These side effects are considered uncommon and not everyone experiences them[3][5].
If you develop sudden swelling, redness, tightness, heat, or pain in one leg, you should consult your doctor immediately, as these could indicate a more serious condition, such as thrombophlebitis[1][4].
Additional warnings:
- Do not use Antistax if you are allergic to red vine leaf extract or any other ingredients in the product[1][3][4].
- Its use is not recommended during pregnancy or breastfeeding due to insufficient data on safety[1][3][5].
- Use in children and adolescents under 18 is not advised, as data are lacking[1][3][4].
Interactions: No interaction studies have been conducted, but always inform your doctor about any other medication you are taking[1][3][4].
Clinical tolerance to Antistax appears favorable, as no significant side effects were observed in comparative studies, but minor adverse effects such as those listed above may occasionally occur[7].
