What is Gabastone 100mg and its Active Ingredient?
Gabastone 100mg contains gabapentin, an anticonvulsant medication that calms overactive nerves. Different gabapentin brands may not be interchangeable, so always follow your doctor's instructions. The 100mg strength is available and is sometimes used when initiating treatment, particularly for pain, before potential adjustments.
Primary FDA-Approved Uses
The FDA has approved gabapentin for:
- Epilepsy (Partial Seizures): Used with other medications to control partial-onset seizures in adults and children aged 3 and older. It manages, but does not cure, epilepsy.
- Postherpetic Neuralgia (PHN): Relieves nerve pain following a shingles infection.
Common Off-Label Uses
Doctors may also prescribe gabapentin off-label for other conditions:
- Diabetic Neuropathy: Nerve pain and tingling caused by diabetes.
- Restless Legs Syndrome (RLS): Helps reduce the urge to move legs in moderate-to-severe RLS. A different formulation, Horizant, is FDA-approved for RLS.
- Other Neuropathic Pain: Chronic nerve pain from injuries or conditions affecting the back and neck.
- Hot Flashes: Can help treat hot flashes in menopausal women or those undergoing breast cancer treatment.
How Gabastone Works in the Body
Gabapentin is believed to work by affecting calcium channels on nerve cells. This action reduces the release of neurotransmitters that cause pain signals and seizures, thus calming nerve activity.
Administration
Gabapentin comes in capsules, tablets, and oral solutions. The medication is typically initiated at a lower strength and then adjusted based on individual response and tolerance to find the most effective amount for the specific condition being treated. Immediate-release forms like Gabastone are usually taken several times a day. It is important to take the medication as prescribed and not to stop suddenly, as this can lead to withdrawal symptoms or an increase in seizure frequency.
Common Side Effects and Warnings
Common side effects include dizziness, drowsiness, unsteadiness, fatigue, nausea, vomiting, and swelling. Less common but more serious side effects include allergic reactions, severe breathing issues (especially with opioids), and worsening depression or suicidal thoughts, which require immediate medical help.
