  • before eye surgery, to help keep the pupil open during surgery, or
  • after eye surgery or injury, to control pain and/or inflammation,
  • to reduce the symptoms, such as red, runny or itchy eyes associated with seasonal allergic conjunctivitis (hayfever). 2. Things to consider before you start to use Voltarol Ophtha

Some people MUST NOT have Voltarol Ophtha. Talk to your doctor if:

  • you think you may be allergic to diclofenac sodium, aspirin or any other NSAIDs, or to any of the other ingredients of the eye drops. (These are listed at the end of the leaflet.) You should also ask yourself these questions before you have Voltarol Ophtha:
  • Do you have an eye infection?
  • Are you using any other eye drops?
  • Do you have any bleeding disorders?
  • Are you pregnant or breast feeding? If the answer to any of these questions is YES, tell your doctor or pharmacist because Voltarol Ophtha might not be the right medicine for you. Are you taking other medicines? Voltarol Ophtha may interfere with other drugs you might be taking or using. Tell your doctor if you are taking any of these drugs.
  • Medicines to prevent your blood clotting.
  • Eye drops or ointment containing steroids such as hydrocortisone or betamethasone. Always tell your doctor or pharmacist about all the medicines you are taking. This means medicines you

have bought yourself as well as medicines on prescription from your doctor. Pregnancy, breast-feeding and fertility If you are pregnant or breast-feeding, think you may be pregnant or are planning to have a baby, ask your doctor or pharmacist for advice before taking this medicine. Pregnancy Voltarol Ophtha should not be used if you are in the last 3 months of pregnancy. You should not use Voltarol Ophtha during the first 6 months of pregnancy unless clearly necessary and advised by your doctor. If you need treatment during this period, the lowest dose for the shortest time possible should be used. Oral forms (e.g. tablets) of diclofenac can cause adverse effects in your unborn baby. It is not known if the same risk applies to Voltarol Ophtha when it is used in the eye. Will there be any problems with driving or using machinery? Some people may have problems with their eyes such as blurred vision, while they are being treated with Voltarol Ophtha. If you are affected, you should not drive or use machinery. Other special warnings

  • The eye drops contain polyoxyl 35 castor oil which can sometimes cause skin reactions.
  • If you are using more than one sort of eye drops leave five minutes between applications. 3. How to use Voltarol Ophtha When Voltarol Ophtha is being used during eye surgery the doctor will work out the correct dose.

If you have been prescribed the drops to use at home the doctor will tell you how and when to use them. Always follow the doctor's instructions carefully. The usual dose is 1 drop in the affected eye 4 times a day. How often you use the drops, and how long you use them for, will be different depending on your condition. The dose will be on the pharmacist's label. Check the label carefully. If you are not sure, ask your doctor or pharmacist. Instructions for using the eye drops are given at the end of this leaflet. These drops should not be used in children under 18 years old. What if you forget to use the drops? If you miss a dose continue with the next dose as normal. Do not double the dose to make up for the one you missed. What if you use too much? If you use too much or if you accidentally swallow the eye drops, see your doctor at once or go to your nearest hospital casualty department. Take your medicine with you.

Technical information intended for healthcare professionals (doctors and pharmacists). The Summary of Product Characteristics (SmPC) is the official document approved by the MHRA/EMA. It does not replace the patient leaflet or a doctor’s advice.

v. The relief of the ocular signs and symptoms of Seasonal Allergic Conjunctivitis (SAC).

vi. Treatment of inflammation and discomfort after strabismus surgery

vii. Treatment of ocular pain and discomfort after radial keratotomy

4.2. Posology and method of administration

Voltarol Ophtha eye drop solution is for instillation into the conjunctival sac only. It should never be injected subconjunctivally, nor should it be directly introduced into the anterior chamber of the eye.

NOTE: The contents remain sterile until the original closure is broken. Each Voltarol Ophtha SDU is for single use only. Discard the single dose unit immediately after use. Patients must discard residual contents after use.

Paediatric use: Voltarol Ophtha and Voltarol Ophtha SDU are not indicated for use in children. Paediatric experience is limited to a few published clinical studies in strabismus surgery.

4.3. Contraindications

Patients with known hypersensitivity to any of the ingredients.

Like other non-steroidal anti-inflammatory agents, Voltarol Ophtha is also contraindicated in patients in whom attacks of asthma, urticaria or acute rhinitis are precipitated by acetylsalicylic acid or by other drugs with prostaglandin synthetase inhibiting activity. Intraocular use during surgical procedure is also contraindicated.

4.4. Special warnings and precautions for use

The anti-inflammatory activity of ophthalmic non-steroidal anti-inflammatory agents (NSAIDs) may mask the onset and/or progression of ocular infections. In the presence of infection, or if there is a risk of infection, appropriate therapy (e.g. antibiotics) should be given concurrently with Voltarol Ophtha.

Although there have been no reported adverse events, there is a theoretical possibility that patients receiving other medications which may prolong bleeding time, or with known haemostatic defects may experience exacerbation with Voltarol Ophtha.

Caution should be exercised when topical NSAIDs such as diclofenac are used concomitantly with topical steroids (see section 4.5 Interaction with other medicinal products and other forms of interaction).

Following instillation of the eye drops, nasolacrimal occlusion or closing the eyes for 3 minutes may reduce the systemic absorption. This may result in a decrease in systemic side effects and an increase in local activity.

4.5. Interaction with other medicinal products and other forms of interaction

Concomitant use of topical NSAIDs such as diclofenac and topical steroids in patients with significant pre-existing corneal inflammation may increase the risk of developing corneal complications, therefore caution should be used.

To prevent the active substances from being washed out when additional ophthalmic medication is used, an interval of at least 5 minutes between each application should be adhered to.

4.6. Pregnancy and lactation

Pregnancy

There are no clinical data from the use of Voltarol Ophtha or Voltarol Ophtha Multidose during pregnancy. Even if systemic exposure is lower compared with oral administration, it is not known if the systemic Voltarol Ophtha or Voltarol Ophtha Multidose exposure reached after topical administration can be harmful to an embryo/foetus.

During the first and second trimester of pregnancy, Voltarol Ophtha or Voltarol Ophtha Multidose should not be used unless clearly necessary. If used, the dose should be kept as low and duration of treatment as short as possible.

During the third trimester of pregnancy, systemic use of prostaglandin synthetase inhibitors including diclofenac may induce cardiopulmonary and renal toxicity in the foetus. At the end of the pregnancy prolonged bleeding time in both mother and child may occur, and labour can be delayed. Therefore, Voltarol Ophtha or Voltarol Ophtha Multidose is not recommended during the last trimester of pregnancy.

Lactation

Diclofenac is excreted in breast milk. However, at therapeutic doses of Voltarol Ophtha no effects on the suckling child are anticipated. Use of ocular diclofenac is not recommended during breast feeding unless the expected benefits outweigh the possible risks.

4.7. Effects on ability to drive and use machines

Patients with blurred vision should refrain from driving a vehicle or operating machines.

4.8. Undesirable effects

Very frequent: Eye pain.

The other frequently observed adverse reaction is a transient, mild to moderate eye irritation.

Other less frequently observed reactions are eye pruritus, ocular hyperaemia and blurred vision immediately after instillation of the eye drops.

Punctate keratitis or corneal disorders have been observed, usually after frequent application.

In patients with risk factors of corneal disorders such as during the use of corticosteroids or with concomitant diseases such as infections or rheumatoid arthritis, diclofenac has been associated, in rare cases, with ulcerative keratitis, corneal thinning, punctuate keratitis, corneal epithelium defect and corneal oedema, which might become sight-threatening. Most patients were treated for a prolonged period of time.

Allergic conditions have been reported for ocular reactions such as conjunctival hyperaemia, allergic conjunctivitis, eyelid erythema, oedema, and pruritus, and systemic hypersensitivity reactions such as urticaria, rash, eczema, erythema, pruritus, cough and rhinitis.

In rare cases dyspnoea and exacerbation of asthma have been reported.

Reporting of suspected adverse reactions

Reporting suspected adverse reactions after authorisation of the medicinal product is important. It allows continued monitoring of the benefit/risk balance of the medicinal product. Healthcare professionals are asked to report any suspected adverse reactions via the Yellow Card Scheme. Website: www.mhra.gov.uk/yellowcard

4.9. Overdose

There is practically no risk of adverse effects due to accidental oral ingestion, since the eye drop solution in a block of 10 units contains only 3mg of diclofenac sodium, corresponding to about 1.8% of the recommended maximum daily adult dose of Voltarol after oral administration. By way of comparison, the maximum oral daily dose for diclofenac sodium recommended in children is 2mg/kg body weight.
