In the presence of eye problems, the Normax preparation is recommended to use 1-2 drops in each affected eye, four times a day. If required, then on the first day of use, the indicated dosage can be increased. In this case, 1-2 drops of the drug are used every two hours.

If the patient has chronic or acute trachoma, Normax is used in the amount of two drops in each eye, from 2 to 4 times a day for 1-2 months.
The dosage of the drug for ear diseases is similar to that described above (1-2 drops in each ear canal, four times a day). However, before the treatment procedure, it is imperative to carry out ear sanitation.
Drops must be at body temperature before use in otolaryngology. To do this, they must be warmed in the palm of your hand. Further, the patient should take a position “on his side” or simply throw his head back (to the right / left) to facilitate the procedure of instillation of the drug solution.
After the drug enters the ear canal, it is necessary to give the drops the opportunity to drain deep inside. To do this, experts recommend pulling the earlobe down and back a little. In this position, it is advisable not to change the position for about two minutes. In some cases, doctors advise patients to place a small lump of cotton wool in the ear canal.
