The typical dosage used for HCSE is 300 milligrams twice daily for two to 16 weeks.
Sclerotherapy
Sclerotherapyis the most common procedure for varicose veins.
It treats both spider veins and small varicose veins.
During the procedure, a chemical is injected into different areas of the veins using ultrasound imaging for guidance.
Taking daily walks and wearing compression stockings for two to three weeks is needed to prevent possible side effects.
Radiofrequency or laser energy is then used to heat the vessel, causing it to close.
It may take up to one year for the vein to disappear.
Common side effects of endovenous ablation include bruising, pain, and changes in skin color.
Serious side effects such as numbness, skin burns, and blood clots are rare.
The laser light then fades the vein away without causing damage to the skin.
Three or more treatments might be needed to get complete results.
Full recovery takes one to four weeks.
Though ligation and stripping were once common treatments, the procedures are now only done in severe cases.
Summary
Treatment for varicose veins has significantly improved thanks to modern technological advances.
Although surgical procedures were once common treatments for varicose veins, they are now only used in extreme cases.
This is mainly because they require longer recovery than less invasive interventions and have more potential side effects.
