Patient leaflet - Paracetamol Codeine and Caffeine 500 mg / 8 mg / 30 mg soluble tablets
1. WHAT CODASOLVE EFFERVESCENT TABLETS ARE AND WHAT THEY ARE USED FOR
Codasolve Effervescent Tablets contain the active ingredients codeine phosphate hemihydrate 8 mg, paracetamol 500 mg and caffeine 30 mg.
This medicine can be used in patients over 12 years of age for the short term treatment of acute moderate pain which is not relieved by paracetamol, ibuprofen or aspirin alone. They are used to relieve migraine, headache, dental pain, period pain, backache, rheumatic pain, strains and sprains, and sciatica.
Codeine belongs to a group of medicines called opioid analgesics which act to relieve pain. Paracetamol is another analgesic to relieve pain. Caffeine acts to further help the effectiveness of paracetamol.
2. WHAT YOU NEED TO KNOW BEFORE YOU TAKE CODASOLVE EFFERVESCENT TABLETS
This medicine contains codeine which can cause addiction if you take it continuously for more than three days. This can give you withdrawal symptoms from the medicine when you stop taking it. This medicine contains paracetamol.
During treatment with Codasolve Effervescent Tablets, tell your doctor straight away if:
If you have severe illnesses, including severe renal impairment or sepsis (when bacteria and their toxins circulate in the blood leading to organ damage), or you suffer from malnutrition, chronic alcoholism or if you are also taking flucloxacillin (an antibiotic). A serious condition called metabolic acidosis (a blood and fluid abnormality) has been reported in patients in these situations when paracetamol is used at regular doses for a prolonged period or when paracetamol is taken together with flucloxacillin. Symptoms of metabolic acidosis may include: serious breathing difficulties with deep rapid breathing, drowsiness, feeling sick (nausea) and being sick (vomiting).
Other medicines and Codasolve Effervescent Tablets
Tell your doctor or pharmacist if you are taking or have recently taken any other medicines, including medicines obtained without a prescription.
Certain medicines can interfere with the effectiveness of each other.
It is particularly important to tell your doctor or pharmacist before taking this medicine if you are also on:
- metoclopramide or domperidone (for sickness or stomach problems)
- colestyramine (used to treat high cholesterol)
- monoamine oxidase inhibitors (MAOIs) (used to treat depression)
- probenecid (used to treat gout and hyperuricemia)
- pregabalin and gabapentin (increased risk of respiratory depression)
- blood thinning medicines (anti coagulants) such as warfarin and you need to take a painkiller on a daily basis over a long period. However, you can take occasional doses of Codasolve Effervescent Tablets
gabapentin or pregabalin to treat epilepsy or pain due to nerve problems (neuropathic pain).

- You need to take the medicine for longer than advised by your doctor
- You need to take more than the recommended dose
- You might feel that you need to carry on taking your medicine, even when it doesn’t help to relieve your pain
- You are using the medicine for reasons other than prescribed, for instance, ‘to stay calm’ or ‘help you sleep’
- You have made repeated, unsuccessful attempts to quit or control the use of the medicine
- When you stop taking the medicine you feel unwell, and you feel better once taking the medicine again (‘withdrawal effects’)
If you notice any of these signs, speak to your doctor to discuss the best treatment pathway for you, including when it is appropriate to stop and how to stop safely (See section 3, If you stop taking Codasolve Effervescent Tablets).

If you have Gilbert’s Syndrome (familial non-haemolytic jaundice)

Taking higher doses or more frequent doses of opioids, such as codeine (an active ingredient of this medicine), may increase the risk of addiction. Overuse and misuse can lead to overdose and/or death.
Rarely, increasing the dose of this medicine can make you more sensitive to pain. If this happens, you need to speak to your doctor or pharmacist about your treatment. Please refer Section 3 ‘How to take Codasolve Effervescent Tablets’ for information on correct dosages and time intervals.

Talk to your doctor or pharmacist if you experience any of the following symptoms while taking Codasolve Effervescent Tablets
- You experience pain or increased sensitivity to pain (hyperalgesia) which does not respond to a higher dosage of your medicine.
Sleep-related breathing disorders
Codasolve Effervescent Tablets can cause sleep-related breathing disorders such as sleep apnoea (breathing pauses during sleep) and sleep related hypoxemia (low oxygen level in the blood).

Warnings and precautions
Tolerance, dependance, and addiction
This medicine contains codeine which is an opioid medicine. It can cause dependence and/or addiction.
Repeated use of opioids can result in the drug being less effective (you become accustomed to it, known as tolerance). Repeated use of Codasolve Effervescent Tablets can also lead to dependence, abuse and addiction, which may result in life-threatening overdose. The risk of these side effects can increase with a higher dose and longer duration of use.
Dependence or addiction can make you feel that you are no longer in control of how much medicine you need to take or how often you need to take it. The risk of becoming dependent or addicted varies from person to person. You may have a greater risk of becoming dependent on or addicted to Codasolve Effervescent Tablets if:
- You or anyone in your family have ever abused or been dependent on alcohol, prescription medicines or illegal drugs (“addiction”).
- You are a smoker
You have ever had problems with your mood (depression, anxiety, or a personality disorder) or have been treated by a psychiatrist for other mental illnesses.
- if you are taking other medicines that can affect liver function
- if you have glucose-6-phosphatase dehydrogenase deficiency
- if you have haemolytic anaemia
- if you have glutathione deficiency
- if you are dehydrated
- if you have a poor diet such that the diet causes health problems
- if you weigh less than 50kg
- if you are elderly
- if you have a condition called myasthenia gravis which weakens the muscles
They may reduce your dose or increase the time interval between doses of your medicine.
Codeine is transformed to morphine in the liver by an enzyme. Morphine is the substance that produces pain relief. Some people have a variation of this enzyme, and this can affect people in different ways.
In some people, morphine is not produced or produced in very small quantities, and it will not provide enough pain relief. Other people are more likely to get serious side effects because a very high amount of morphine is produced.
If you notice any of the following side effects, you must stop taking this medicine and seek immediate medical advice: Slow or shallow breathing, confusion, sleepiness, small pupils, feeling or being sick, constipation, lack of appetite.
Talk to your doctor or pharmacist before taking Codasolve Effervescent Tablets:
- If you are or have ever been addicted to opioids, alcohol, prescription medicines, or illegal substances
If you have previously suffered from withdrawal symptoms such as agitation, anxiety, shaking or sweating, when you have stopped taking alcohol or drugs.
