It is best to avoid sex while using Clintin-CL Vaginal Softgel Capsule and to wait at least 2 to 3 days after finishing the full course. Having sex too soon can make the treatment less effective, cause irritation, and increase the risk of reinfection or transmitting the infection to your partner. If you are unsure or still have symptoms, please consult your doctor or gynaecologist before resuming sexual activity.
