Powder For Suspension
Famotack 40 mg/5 ml Powder For Suspension
Generic: Famotidine
Manufacturer: Square Pharmaceuticals PLC, Gazipur
Therapeutic class: H2 Receptor Antagonist (H2 Blocker)
What is Famotack?
Famotack 40 mg/5 ml powder for suspension from Square Pharmaceuticals PLC, Gazipur contains Famotidine, a histamine H2-receptor antagonist (H2 blocker) that reduces stomach acid production. It is used for heartburn, acid indigestion, gastro-oesophageal reflux and peptic ulcers. Famotack is milder than proton pump inhibitors, making it a practical choice for less severe or occasional acid symptoms.
Famotidine works by blocking histamine H2 receptors on the acid-producing cells of the stomach lining. Histamine normally signals these cells to release acid; with the receptors blocked, both the amount and concentration of acid fall. The effect begins within about an hour and lasts roughly 10-12 hours, which is why it is often dosed once or twice daily.
Indications
Famotidine is indicated for:
- Heartburn and acid indigestion — relief and prevention of occasional symptoms
- Gastro-oesophageal reflux disease (GERD) — mild to moderate cases
- Duodenal and gastric ulcers — treatment and prevention of recurrence
- Zollinger-Ellison syndrome — conditions of acid hypersecretion
- Stress ulcer and aspiration prophylaxis — in selected hospital settings
It is sometimes preferred when a milder, shorter-acting acid reducer is enough, or for night-time symptom control. A registered doctor should confirm which indication applies to you.
Dosage & Administration
Usual adult doses of Famotack:
- Heartburn/indigestion: 10-20 mg once or twice daily; may be taken 15-60 minutes before food that triggers symptoms
- GERD: 20 mg twice daily for 6-12 weeks
- Duodenal/gastric ulcer: 40 mg at bedtime (or 20 mg twice daily) for 4-8 weeks; 20 mg at bedtime for maintenance
Famotack can be taken with or without food. Doses are reduced in significant kidney impairment, so tell your doctor about kidney disease. The exact dose and duration must be decided by a registered doctor; in children, dosing is weight-based and strictly per the doctor's prescription.
Side Effects
Famotidine has a good safety record. Possible side effects include:
- Common: headache, dizziness, constipation, diarrhoea
- Less common: dry mouth, nausea, fatigue, skin rash
- Rare: confusion or agitation (mainly in the elderly or those with kidney failure), irregular heartbeat, liver enzyme changes, low blood counts
Most effects are mild and temporary. Seek medical attention if you develop a fast or irregular heartbeat, marked confusion, easy bruising, yellowing of the skin, or signs of allergy such as swelling and breathing difficulty.
Precautions & Warnings
Precautions while using Famotidine:
- Kidney impairment: doses usually need reduction; elderly patients with poor kidney function are prone to confusion
- Persistent heartburn despite 2 weeks of treatment, difficulty swallowing, vomiting blood or black stools require medical evaluation — acid reducers can mask stomach cancer symptoms
- Avoid smoking, alcohol, and late heavy meals, which counteract acid control
- Do not combine with other H2 blockers; tell your doctor if you also use a PPI
- Use the lowest dose that controls symptoms, for the shortest necessary time
Drug Interactions
Famotidine has fewer drug interactions than older H2 blockers like cimetidine, but note:
- Acid-dependent drugs: reduced absorption of ketoconazole, itraconazole, atazanavir, rilpivirine and some iron salts
- Antacids: may slightly reduce famotidine absorption — separate by 1-2 hours if possible
- Tizanidine: levels may increase with strong acid suppression combinations
- Probenecid: can raise famotidine blood levels
Famotidine does not significantly inhibit liver CYP enzymes, which is one reason doctors choose it. Still, list all your medicines to your doctor and pharmacist.
Contraindications
Famotidine should not be taken if:
- You have known hypersensitivity to famotidine, other H2-receptor antagonists, or any ingredient of the powder for suspension
- Cross-sensitivity exists between H2 blockers, so a previous reaction to ranitidine or similar drugs matters
Use with caution and medical guidance in moderate to severe kidney disease (dose adjustment needed), in the elderly, and in patients with long QT syndrome where high doses are used. If alarm symptoms are present, endoscopic evaluation should come before prolonged acid suppression.
Pregnancy & Lactation
Pregnancy: Famotidine has been used in pregnancy for many years without evidence of harm in available studies, and H2 blockers are often considered acceptable for pregnancy heartburn when lifestyle measures fail. Even so, it should be taken in pregnancy only on a doctor's advice, at the lowest effective dose.
Lactation: Famotidine passes into breast milk in small amounts, generally regarded as compatible with breastfeeding at usual doses; among H2 blockers it transfers relatively less. Nursing mothers should still confirm with their doctor before regular use.
Storage Conditions
Store below 30°C in a dry place, protected from light and moisture. Keep the powder for suspension in its original packaging, tightly closed, and out of the reach and sight of children. If using a suspension form, follow the label about shaking and any post-reconstitution shelf life. Do not use after the expiry date on the pack.
Frequently Asked Questions
Is Famotack weaker than omeprazole or other PPIs?
<p>Famotack (famotidine) reduces acid less profoundly than PPIs like omeprazole, but that is not always a disadvantage. It acts faster — within about an hour — making it useful for predictable, occasional heartburn and night-time symptoms. PPIs suit severe reflux, erosive oesophagitis and ulcer healing better. Doctors sometimes use both classes together for difficult night-time acid breakthrough. Your doctor will match the medicine to the severity of your condition.</p>
Can I take Famotack only when I get heartburn, instead of every day?
<p>For occasional heartburn, on-demand use of Famotack is reasonable — it starts working within about an hour, and taking it 15-60 minutes before a meal you expect to cause trouble can prevent symptoms. However, if you need it more than two or three times a week, or your doctor prescribed a fixed course for ulcer or GERD healing, take it regularly as directed and get reviewed rather than self-treating long term.</p>
Is long-term use of Famotack safe?
<p>Famotidine is considered one of the safer acid reducers, and maintenance use is common under medical supervision — for example 20 mg at night to prevent ulcer recurrence. Long-term users should have periodic doctor reviews, kidney function checks where relevant, and reassessment of whether treatment is still needed. Unsupervised use for months is not advisable, because ongoing symptoms may signal a condition needing investigation.</p>
