Rinocidina 7.5 mg + 3 mg nasal drops, solution
Naphazoline nitrate + tyrothricin
What it is and what it is used for
Rinocidina is a medicine based on naphazoline nitrate (nasal decongestant) and tyrothricin (an antibiotic effective in the local treatment of nasal infections).
This medicine is used in the topical treatment of bacterial inflammations of the nasal mucosa (rhinitis) and paranasal sinuses (sinusitis).
Consult your doctor if you do not feel better or if you feel worse after 7 days.

Warnings and precautions
Consult your doctor or pharmacist before using Rinocidina
- if you are elderly and/or your prostate volume is increased (prostatic hypertrophy), because your urine could be retained in your bladder (urinary retention).
- if you suffer from heart disease, especially in the case of high blood pressure (hypertension), the use of the medicine will be evaluated by your doctor on a case-by-case basis
- if sudden symptoms appear such as: severe headache, nausea, vomiting, vision problems. The doctor may decide to stop the therapy. In most cases, these symptoms improve or resolve within a few days following appropriate treatment.
- in case of loss of smell
The use, especially if prolonged, of products applied directly to the affected area (topical products) can lead to sensitisation phenomena; in such a case, it is necessary to interrupt the treatment and, if necessary, consult the doctor who must establish an appropriate therapy.
The prolonged use of vasoconstrictors (a category of medicines to which Rinocidina belongs) can alter the normal function of the nasal and paranasal sinus mucosa, also inducing habituation to the medicine. The use of the medicine for long periods of time can be harmful.
Children and Adolescents
RINOCIDINA is contraindicated in children under 12 years of age (see paragraph Do not use Rinocidina).
Possible side effects
Like all medicines, this medicine can cause side effects, although not everyone experiences them.
The medicine can cause a worsening of the sensation of nasal obstruction, irritation and swelling of the blood vessels of the inner wall of the nose (rebound phenomena of sensitisation and mucosal congestion). Rapid absorption of the medicine through the inflamed inner walls of the nose (mucosa) can lead to the following effects involving the whole body (systemic):
• an increase in arterial blood pressure (arterial hypertension); an excessive slowing of the heartbeat (reflex bradycardia)
• headache
• urinary problems (micturition disorders)
