1. What INTERFRIN is and what it is used for
This medicine belongs to the group of medicines called Sympathomimetics. It is a nasal decongestant that contains oxymetazoline as the active ingredient. Oxymetazoline, when administered nasally, produces local vasoconstriction, decongesting the nasal mucosa.
It is indicated for the local and temporary relief of nasal congestion in adults and children from 6 years of age.
You should consult a doctor if your symptoms worsen or do not improve after 3 days of treatment.
2. What you need to know before using INTERFRIN

- If you are allergic to oxymetazoline, other nasal decongestants, or any of the other components of this medicine (listed in section 6).
- If you have recently undergone head surgery (if you have had any cranial, transnasal, or transoral surgical intervention).
Warnings and precautions
Inform your doctor or pharmacist before starting to use INTERFRIN if:
- You are being treated with antidepressant medications, phenothiazine (a tranquilizer), or methyldopa (for high blood pressure).

- If you have any thyroid disease (hyperthyroidism)
- If you have ever experienced insomnia or dizziness when treated with other sympathomimetic medications, such as those used to treat heart disease, hypotension (low blood pressure), or asthma.
In rare cases, oxymetazoline can increase nasal congestion instead of reducing it due to its temporary effects and prolonged use; this is known as rebound effect.
Insomnia can rarely occur after using the medicine. If this happens, avoid using it in the late afternoon or evening.
