Anadol 100 mg/2 ml Injection

Anadol 100 mg/2 ml injection is manufactured and marketed by Square Pharmaceuticals PLC, Pabna in Bangladesh. It contains Tramadol Hydrochloride, an opioid-type painkiller used for moderate to moderately severe pain. Anadol is a strictly prescription-only medicine: it can cause drowsiness, dependence and addiction when misused, and it must never be bought or taken casually for everyday aches.

Tramadol works in two ways. It attaches to opioid receptors in the brain and spinal cord, dulling how pain signals are felt, and it also increases the brain chemicals serotonin and noradrenaline, which further dampens pain pathways. This double action makes it effective for significant pain — but the same brain effects explain its risks of sedation, dependence and withdrawal symptoms.

Anadol is prescribed only when milder painkillers (such as paracetamol or NSAIDs) are insufficient or unsuitable. Doctor-approved uses include:

• Moderate to moderately severe acute pain, such as after surgery or significant injury
• Severe musculoskeletal pain (for example disc-related back pain) for short periods
• Cancer-related pain as part of a structured pain-management plan
• Other chronic painful conditions when a specialist judges an opioid-type drug is justified

It is not a medicine for headaches, routine body aches or self-treatment, and it should never be used to stay awake, improve mood or boost energy — such misuse is dangerous and habit-forming.

Dosage must be set by a doctor — never adjust it yourself. Typical adult dosing:

• Immediate-release: 50–100 mg every 4–6 hours only when needed for pain
• Maximum: 400 mg in 24 hours (lower in elderly people and in kidney or liver disease)
• Sustained-release forms: usually twice daily, swallowed whole — never crushed or chewed

Anadol may be taken with or without food. Use the lowest effective dose for the shortest possible time. Do not take it more often than prescribed, do not share it with anyone, and after regular use for more than a couple of weeks never stop suddenly — your doctor will taper the dose gradually to avoid withdrawal symptoms.

Side effects are common, especially when starting:

• Common: nausea, vomiting, dizziness, drowsiness, constipation, dry mouth, sweating, headache
• Less common: itching, confusion, sleep disturbance, blurred vision, difficulty passing urine
• Serious (emergency): seizures (fits), very slow or shallow breathing, extreme sleepiness or unresponsiveness, serotonin syndrome (high fever, agitation, muscle twitching, rapid heartbeat), allergic swelling of the face or throat

Long-term use can lead to tolerance (needing more for the same effect), dependence and addiction. Stopping suddenly causes withdrawal — restlessness, anxiety, sweating, body aches, insomnia and diarrhoea — which is why the dose must be tapered under medical guidance.

Anadol demands strict caution:

• Use it only with a valid prescription and exactly as directed — misuse of tramadol is a serious and growing problem in Bangladesh
• Do not drive, ride motorcycles or operate machinery until you know how it affects you
• Never mix it with alcohol, sleeping pills or other sedatives — the combination can dangerously suppress breathing
• Tell your doctor if you have epilepsy, head injury, breathing problems, kidney or liver disease, depression, or any history of substance misuse
• Keep it locked away from others, especially teenagers and young adults
• Do not stop suddenly after regular use — ask your doctor for a tapering plan

Dangerous interactions are possible — tell your doctor about every medicine you take:

• Antidepressants (SSRIs such as escitalopram or sertraline, SNRIs, TCAs) — risk of serotonin syndrome and seizures
• MAO inhibitors — must not be used together or within 14 days
• Sedatives: benzodiazepines, sleeping pills, antihistamines, antipsychotics, alcohol — dangerous breathing suppression
• Other opioids — additive overdose risk
• Carbamazepine — reduces tramadol's effect and may increase seizure risk
• Warfarin — bleeding tendency may rise; monitoring needed

Avoid alcohol completely while taking Anadol.

Anadol must not be used in the following situations:

• Children under 12 years (and not after tonsil or adenoid surgery in anyone under 18)
• Severe breathing problems, such as a severe asthma attack or respiratory depression
• Acute intoxication with alcohol, sleeping pills, opioids or other sedating drugs
• Use of MAO-inhibitor antidepressants currently or within the last 14 days
• Uncontrolled epilepsy
• Known allergy to tramadol or other opioids
• Severe kidney or liver failure, unless a specialist specifically adjusts therapy

People with a history of drug or alcohol addiction should generally avoid tramadol; safer alternatives exist.

Pregnancy: Tramadol Hydrochloride is not recommended during pregnancy. Regular use, particularly in the later months, can cause the newborn to suffer withdrawal symptoms (irritability, tremors, poor feeding, breathing problems) after birth. It should be used only if a doctor judges the benefit clearly outweighs the risk.

Breastfeeding: Tramadol passes into breast milk and can make the baby unusually sleepy or affect breathing, so it is generally not recommended while breastfeeding. If a nursing mother genuinely needs strong pain relief, the doctor will choose the safest option and monitor the baby for excessive drowsiness or poor feeding.

Store Anadol at room temperature below 30°C in its original pack, away from light and moisture. Because tramadol is a frequently misused medicine, keep it locked away and strictly out of reach of children, teenagers and anyone it was not prescribed for. Never share your tablets with others, even for similar pain. Count and keep track of your tablets, return unused medicine to a pharmacy where possible, and never keep leftover tramadol at home for future self-medication. Do not use it beyond the expiry date.
