Pregnancy & Lactation
The safety of Diclofenac eye drops in pregnancy & lactation has not been established and its use therefore is not recommended unless the potential benefit to the mother outweighs the possible risk to the child.
Precautions & Warnings
Diclofenac eye drops may mask the signs of infection. So physicians should be alert to the development of infections in patients receiving the drug. During prolonged use, it is recommended that physicians conduct periodic examinations of the eye, including measurement of the intraocular pressure. Contact lenses should not be worn during treatment.
Accidental ingestion of Diclofenac Sodium presents virtually no risk of unwanted effects, since one 5 ml bottle of eye drop solution contains only 5 mg of Diclofenac Sodium, which is equivalent to about 3% of the recommended maximum oral dose for adults.
Ophthalmic Non-Steroid drugs
