How Nac Aq Injection works

Diclofenac blocks the chemicals your body makes at a site of injury or inflammation, which reduces pain, swelling and fever.

How to take Nac Aq Injection

This is given by a doctor or a nurse. Do not attempt to inject it yourself unless you have been trained and told to. Follow the dose and the duration written on your prescription.

Take it exactly as your doctor prescribed. Do not change the dose or stop early on your own.

Missed dose and overdose

If you miss a dose

Take it as soon as you remember. If your next dose is almost due, skip the one you missed — never take two doses together to catch up.

If you take too much

An overdose of this medicine can cause stomach bleeding, kidney failure, drowsiness and fits. Do not wait for symptoms to appear — go to the nearest emergency department and take the pack or strip with you.

Side effects of Nac Aq Injection

Most side effects of Nac Aq are mild and settle as the body adjusts. Reported side effects include:

  • Indigestion
  • Stomach pain
  • Nausea
  • Heartburn
  • Dizziness
  • Swelling of the ankles and feet

Stop the medicine and seek help immediately for a rash, swelling of the face or lips, wheezing or difficulty breathing. Tell your doctor about any side effect that persists or worries you.

Safety advice for Nac Aq Injection

PregnancyNot recommended in pregnancy — it may harm the developing baby. Tell your doctor at once if you are or might be pregnant.
BreastfeedingUse with caution while breastfeeding; watch the baby for any unusual symptoms.
AlcoholDo not drink alcohol while taking this medicine.
DrivingMay cause drowsiness or affect your concentration. Do not drive until you know how it affects you.
KidneyConsult your doctor if you have kidney disease.
LiverConsult your doctor if you have liver disease.
Habit formingNo

Warnings and precautions

Take it with or just after food, and for the shortest time that works. Stop and seek urgent care for black or tarry stools, vomiting blood, or severe stomach pain — this group can cause bleeding from the stomach. Long or high-dose use raises the risk of heart attack, stroke and kidney injury, particularly in older people and those already at risk. Avoid if you are dehydrated or have an illness with vomiting or loose motions — the kidneys are vulnerable then. Must be avoided in the last three months of pregnancy.

Do not take Nac Aq if

Not for anyone with a known allergy to this medicine or to any ingredient in the pack. Not for people with an active stomach ulcer, severe kidney or heart failure, or asthma triggered by aspirin or anti-inflammatory painkillers. Not in the third trimester of pregnancy.

Interactions with other medicines

Combining with a blood thinner or aspirin sharply raises the bleeding risk. Reduces the effect of blood pressure medicines and water tablets, and together with them can harm the kidneys. Never take two anti-inflammatory painkillers at the same time.

How to store Nac Aq Injection

Store as printed on the carton — some injections need refrigeration and must not be frozen. Keep out of the reach of children.

Expert advice for Nac Aq Injection

Use the lowest dose for the shortest period. If you need a painkiller regularly, see your doctor rather than continuing on your own. Paracetamol is the safer choice for simple fever and headache.
