Uses of Isojol Tablet

Influenza (flu)
Herpes Simplex Virus Infections
Genital warts
Respiratory tract infection

Benefits of Isojol Tablet

Influenza (flu)
Flu brings fever, body ache, cough, weakness, and sore throat, making daily tasks difficult. Isojol Tablet improves your immune response to help your body fight the flu virus more efficiently. It may shorten the duration of symptoms, reduce their intensity, and support quicker recovery, helping you return to normal routine sooner.

Herpes Simplex Virus Infections
Herpes infections cause painful blisters, burning, and discomfort around the mouth or genitals. Isojol Tablet helps your body fight the virus more effectively by strengthening immune activity, which reduces outbreak severity and helps the sores heal faster. With regular use, it may also lower the chances of recurrent flare-ups, helping you feel more comfortable and recover sooner.

Genital warts
Genital warts are caused by a viral infection that leads to small, persistent skin growths in intimate areas, often causing embarrassment and irritation. Isojol Tablet supports the immune system in clearing the virus, helping reduce the size and number of warts over time. It promotes faster recovery, helps prevent new warts from forming, and improves overall comfort and confidence.

Respiratory tract infection
Respiratory infections affect the nose, throat, or lungs and can cause cough, congestion, fever, and breathing difficulty. Isojol Tablet improves the body’s natural defense mechanisms, helping it combat the viral infection more effectively. It can reduce symptom severity, speed up recovery, and improve breathing comfort, supporting better overall health during illness.
