Prostil is useful in the treatment of tinnitus, but it is only part of the treatment of tinnitus. Tinnitus is mostly caused by vascular spasm and viral infection. Treatment requires the administration of vasodilator drugs, such as prostaglandin and betahistine hydrochloride, hormones, such as dexamethasone and prednisone, and nutritional nerve drugs, such as methylcobalamin, etc. If necessary, treatment can be combined with hyperbaric oxygen, etc. The treatment course is usually ten days, and the noise environment should be avoided to reduce the damage to the ear. For acute tinnitus, it is usually accompanied by hearing loss, and the early treatment effect is better. For chronic tinnitus, the treatment effect is worse or even ineffective, and eventually treatment such as hearing aids can be worn. Therefore, tinnitus needs to be treated actively.
