It is often recommended to take the tablets with warm milk or water after meals to aid absorption and reduce the risk of stomach upset. Do not exceed the recommended dose, and consult your doctor before starting it if you have any medical conditions or are taking other medicines.

No, Himalaya Tentex Forte should not be taken without consulting a doctor. Sexual problems can have many underlying causes, and a doctor can assess your condition, review your overall health, and decide whether this medicine is suitable for you, along with proper diet and lifestyle advice.
