The intervention arm will receive phenytoin ointment 20mg per 1cm2 of wound surface area applied in a layer and followed by compression bandage. This will be applied weekly for 12 weeks.
The placebo product will contain emulsifying wax, white soft paraffin and liquid paraffin and 20 mg per 1cm2 of wound surface area will applied, followed by compression bandage weekly for 12 weeks.
Both investigators and patients will be blinded to the intervention; the investigators will record the batch number and product investigation number at the time of the use. The details whether each product contain active drug or the placebo will be recorded by the pharmacists in the study team who have no contact with the study participants and no role in assessing outcomes.
