Baclofen: Uses, Dosage, Side Effects, and More

Baclofen is a muscle relaxant medication that acts as a gamma-aminobutyric acid (GABA) agonist. It binds to GABA receptors in the spinal cord, activating them, which leads to a reduction in the release of neurotransmitters that cause muscle spasms.

Baclofen is available in tablet form with concentrations of 10 mg and 25 mg of the active substance, making Baclofen 10 and Baclofen 25 available.

Indications for Baclofen Use

Baclofen, as a muscle relaxant, is used to alleviate involuntary muscle spasms resulting from various conditions such as multiple sclerosis, spinal cord disorders, cerebrovascular diseases, cerebral palsy, meningitis, and traumatic head injury.

Baclofen for Disc-Related Issues

Disc-related issues, or what is commonly known as herniated discs, can exert pressure on nerves exiting the spinal cord, leading to disruptions in electrical signals transmitted from the nerve to nearby muscle tissues, resulting in painful muscle contractions.

Muscle relaxant medications can help alleviate spasms and reduce pain, allowing for easier movement, and one of the important medications in this category is Baclofen tablets.

Baclofen for the Stomach

One study suggests that this medication may help reduce symptoms associated with gastroesophageal reflux disease (GERD) by reducing the relaxation of the lower esophageal sphincter muscle.

However, there is not enough data to indicate the long-term effectiveness of the drug. Therefore, the study suggested that Baclofen might be a treatment option only for GERD patients who do not respond to proton pump inhibitors.

Baclofen Tablets for Anxiety

One study suggests that this medication may be effective in treating symptoms of post-traumatic stress disorder (PTSD), depression, and the associated anxiety in patients suffering from chronic PTSD.

“More extensive and precise studies are needed to confirm the effectiveness of Baclofen in treating post-traumatic stress disorder and anxiety.”

Baclofen Dosage

The appropriate dosage of Baclofen depends on the type of condition and the patient’s needs. Generally, the dosage starts at a low level and gradually increases to the appropriate level. Here are some typical dosages:

  • For adults: The dosage typically starts at 5 mg three times a day and gradually increases to 25 mg three times a day. In severe cases, the dose may be increased to 100 mg per day.
  • For children: The dosage varies based on age, ranging from 10 to 60 mg daily for children, depending on age and condition.

How to Take Baclofen Tablets

  • Baclofen should be taken according to the doctor’s instructions, and it should not be stopped without consulting a physician.
  • Tablets should be taken with water, and if you experience nausea, it is advisable to take them with a drink, milk, or with food.
  • Baclofen should not be discontinued abruptly due to the possibility of adverse effects, including confusion, hallucinations, and an increase in heart rate. Instead, the dosage should be gradually reduced over a period of one to two weeks, following a doctor’s advice.

Baclofen’s Side Effects

Some side effects may occur when taking Baclofen, including:

  • Fatigue or drowsiness.
  • Nausea.
  • Weakness in limbs or feelings of extreme tiredness, fatigue, and muscle pain.
  • Headache, dizziness, or light-headedness.
  • Breathing difficulties.
  • Changes in mood, confusion, hallucinations, or nightmares.
  • Dry mouth.
  • Vision problems.
  • Tremors or loss of muscle control.
  • Low blood pressure.
  • Gastrointestinal problems, including vomiting, constipation, or diarrhea.
  • Excessive sweating.
  • Skin rash.
  • Increased need to urinate or painful urination.

Baclofen, Pregnancy, and Breastfeeding

  • Baclofen crosses the placenta, so its use during pregnancy should be avoided unless absolutely necessary, and only after consulting a physician to assess the risks and benefits.
  • If Baclofen is taken during pregnancy, the newborn may experience withdrawal symptoms, such as seizures.
  • Regarding breastfeeding, only a minimal amount of the drug passes into breast milk, and although it is not expected to have negative effects on the baby, the use of the drug during breastfeeding should be discussed with a doctor.

Baclofen and Blood Pressure

  • Baclofen should be used cautiously in patients with high blood pressure, as it may negatively affect blood pressure. It may also interact with many high blood pressure medications.

Baclofen and Erectile Function

  • In some cases, but not in all, this medication may negatively affect certain sexual functions, such as erectile function. However, this effect usually ceases when the drug is discontinued.

How Baclofen Works

Baclofen, as a muscle relaxant, works by reducing the transmission of messages between nerve cells and muscles, thereby reducing the likelihood of muscle contraction and spasms.


Baclofen is an important medication used to treat painful muscle spasms and certain neurological disorders. It should be used under a doctor’s guidance, and any possible side effects should be monitored and reported to the physician. Pregnancy and breastfeeding should be approached with caution when using this medication.
