Tylex is a medication that has gained popularity due to its ability to relieve pain and discomfort. It is a combined preparation containing two active components: paracetamol and codeine. This combination allows providing effective relief of pain symptoms of different origin.

What Is Tylex CD ?

Tylex CD is a medication containing 500 mg of paracetamol and 30 mg of codeine in each tablet. Paracetamol is widely known for its analgesic and antipyretic effects, while codeine is a weak opioid agonist that enhances pain relief.

Codeine & Paracetamol

Mexican Codeine and Paracetamol are two key components of Tylex that interact to enhance the overall effects of the drug. Paracetamol blocks the synthesis of prostaglandins, the substances responsible for the appearance of pain and inflammation, while codeine acts on opioid receptors in the brain to reduce the perception of pain.

What Are Tylex CD Tablets Used For ?

Tylex CD tablets are used to relieve various types of pain, from dental pain to muscle spasms. It can also be prescribed for post-surgery, migraines, and back pain.


The dosage of Tylex CD should be prescribed by a doctor depending on the individual needs of the patient. It is generally recommended to take one tablet every 4-6 hours, as needed. The recommended dosage should not be exceeded to avoid possible overdose.


An overdose of the Tylex medicine can lead to serious consequences such as liver damage or even death. Signs of overdose may include nausea, vomiting, loss of appetite, drowsiness, and confusion. Medical attention should be sought immediately if an overdose of the drug is suspected.


The drug is contraindicated in case of individual intolerance to its components, as well as in liver, kidney, lung and heart dysfunctions. Also, its use should be avoided in asthma, chronic obstructive pulmonary disease (COPD) and other respiratory disorders.

Side Effects

Tylex CD (paracetamol-codeine) is an effective combination medicine used to relieve pain of various origins. Most people tolerate it well without serious side effects.   However, like any medicine, Tylex can cause adverse reactions:

Common Side Effects

Nausea and vomiting: These are some of the most common side effects when taking Tylex CD. To reduce the risk of these symptoms, it is recommended to take the drug after meals.

Dizziness and drowsiness: Tylex CD may cause feelings of dizziness and drowsiness, which may affect your ability to concentrate and drive or operate machinery. To avoid accidents, try to avoid activities that require increased concentration until you know how your body reacts to the drug.

Dry mouth: Some patients may experience dry mouth. Drinking adequate amounts of water and moisturizing the mucous membranes is recommended.

Serious Side Effects

Although serious side effects from Tylex CD are rare, they can still occur in the form of:

Allergic reactions: Redness of the skin, itching, rash, and swelling of the face, lips, tongue, or throat may indicate an allergic reaction to the drug.

Abdominal or stomach pain: If you get severe abdominal or stomach pain, it may be a sign of problems with the liver or other organs.

Fast pulse or heartbeat: An unusually high pulse or heartbeat may be associated with the unwanted effects of Tylex CD. If this occurs, stop taking it and seek medical attention.

In addition to the side effects listed above, there is a risk of developing dependence with long-term and improper use of Tylex CD. The drug contains codeine, which belongs to the class of opioids. Taking codeine should be strictly in accordance with the doctor’s recommendations and should not exceed the prescribed dose.

How Long The Effect Lasts

The effect of Tylex usually begins to appear 30-60 minutes after taking it and lasts up to 4-6 hours. However, the duration of action may vary depending on the individual characteristics of the body.


The half-life of Tylex is the time in which the amount of the drug in the body is reduced by half. For codeine, this time is about 3 hours, and for paracetamol it is about 1-4 hours.

Interaction With Other Medicines

Tylex is a combination drug that promotes pain relief through paracetamol and codeine. However, it is important to realize that interactions with other medications may affect the effectiveness and safety of the drug. It is important to familiarize yourself with possible interactions before starting treatment.

With Other Analgesics

Taking Tylex CD together with other analgesics containing paracetamol or other active ingredients may result in exceeding the recommended dose of paracetamol. This may increase the risk of developing liver toxicity.

With Other Opioids

Tylex CD already contains codeine, which is an opioid. Therefore, concomitant administration of other opioid-containing medications (e.g. morphine, oxycodone, etc.) may increase the risks of respiratory depression, drowsiness, and dependence. The use of other opioid medications is not recommended during treatment with Tylex.

With Benzodiazepines & Sedatives

Codeine and benzodiazepines (e.g., diazepam, alprazolam) may cause additional central nervous system depression, leading to drowsiness, slowed reaction time, and potential hazards. The interaction of sedatives with codeine may exacerbate this effect, so concomitant administration of these drugs should be avoided.

With Antidepressants

There is a risk of interaction between Tylex CD and certain antidepressants such as serotonin reuptake inhibitors (e.g. fluoxetine, sertraline). This may increase the risk of developing serotonin excess syndrome, which is characterized by symptoms such as agitation, sweating, trembling, and others.

With Alcohol

Alcohol may also increase the drowsiness and central nervous system depression caused by codeine. Alcohol consumption while taking Tylex CD may increase not only health but also safety risks.
