Drug Class: Third-Generation Cephalosporin Antibiotic | Form: Oral Capsule | Prescription Status: Prescription Only (Rx)
What Is Cefspan 400mg Capsule?
Cefspan 400mg Capsule is a prescription antibiotic containing Cefixime 400mg — a third-generation cephalosporin with broad-spectrum bactericidal activity against a wide range of gram-positive and gram-negative bacteria. Third-generation cephalosporins represent an advanced class of beta-lactam antibiotics with significantly enhanced gram-negative coverage and greater resistance to bacterial beta-lactamase enzymes compared to earlier generation cephalosporins — making Cefixime effective against many organisms that have developed resistance to older antibiotics.
The 400mg capsule is the standard adult dose of Cefixime, typically administered once or twice daily — making it one of the more convenient oral antibiotic regimens available for treating a wide range of serious bacterial infections across multiple organ systems. Cefixime's oral bioavailability, broad spectrum, and once-daily dosing option make it a clinically valuable choice for outpatient management of infections that previously required injectable antibiotics.
Cefspan must only be used under medical supervision for confirmed or strongly suspected bacterial infections. It has no activity against viruses and will not treat viral infections such as the common cold or flu.
What Is Cefspan 400mg Used For?
Cefspan 400mg is prescribed for bacterial infections caused by Cefixime-susceptible organisms, including:
- Respiratory tract infections — acute bronchitis, community-acquired pneumonia, and acute exacerbations of chronic bronchitis caused by susceptible organisms including Haemophilus influenzae and Streptococcus pneumoniae (سانس کی نالی کا انفیکشن)
- Urinary tract infections (UTIs — پیشاب کی نالی کا انفیکشن) — uncomplicated and complicated infections of the bladder (cystitis), urethra (urethritis), and kidneys (pyelonephritis) caused by gram-negative organisms including E. coli and Klebsiella pneumoniae
- Ear infections — otitis media (کان کا انفیکشن) — middle ear infections caused by Haemophilus influenzae, Moraxella catarrhalis, and Streptococcus pyogenes
- Throat infections — pharyngitis and tonsillitis (گلے کا انفیکشن) — bacterial sore throat and tonsil infection, including those caused by Streptococcus pyogenes (Group A Streptococcus)
- Typhoid fever (ٹائیفائیڈ) — enteric fever caused by Salmonella typhi and Salmonella paratyphi — Cefixime is a widely used oral treatment for typhoid in Pakistan
- Uncomplicated gonorrhoea — cervical and urethral gonorrhoea caused by Neisseria gonorrhoeae under specialist guidance
- Skin and soft tissue infections — mild to moderate bacterial infections of skin and underlying soft tissue caused by susceptible organisms
Cefspan is effective only against bacterial infections. It will not treat viral infections including the common cold, flu, or COVID-19. Unnecessary use of antibiotics contributes to antibiotic resistance — always use only when prescribed by a doctor.
How Does Cefspan 400mg Work?
Cefixime 400mg — Third-Generation Cephalosporin Cell Wall Inhibitor: Cefixime belongs to the beta-lactam antibiotic family and works by irreversibly binding to penicillin-binding proteins (PBPs) — enzymes located on the inner surface of the bacterial cell membrane that are essential for the final stages of bacterial cell wall synthesis. The bacterial cell wall is a rigid structural layer made of peptidoglycan that maintains the shape and integrity of the bacterium and protects it from osmotic pressure.
By blocking PBPs, Cefixime prevents the cross-linking of peptidoglycan chains — the process that gives the cell wall its strength. The bacterial cell wall becomes structurally weakened and unable to withstand internal osmotic pressure. The bacterium swells, the cell wall ruptures, and the bacterial cell dies — making Cefixime a bactericidal antibiotic that kills bacteria outright rather than simply slowing their growth.
Third-Generation Advantage: Compared to first and second-generation cephalosporins, Cefixime has significantly enhanced gram-negative coverage — including organisms commonly responsible for UTIs, respiratory infections, and typhoid — and greater stability against many bacterial beta-lactamase enzymes that destroy earlier generation beta-lactam antibiotics. This enhanced stability against resistance mechanisms is what makes third-generation cephalosporins effective against organisms that no longer respond to older antibiotics.

Who Should NOT Take Cefspan 400mg?
Do not take Cefspan if you:
- Have a known allergy to Cefixime, any cephalosporin antibiotic, or penicillin — cross-sensitivity between penicillins and cephalosporins exists in approximately 1 to 10% of patients; inform your doctor of any penicillin allergy before taking cephalosporins
- Have had a severe allergic reaction (anaphylaxis) to any beta-lactam antibiotic — including penicillins, cephalosporins, or carbapenems
- Are under 6 months of age — safety not established in very young infants
Always consult your doctor before use if you:
- Have kidney impairment — dose reduction is required as Cefixime is primarily renally excreted
- Have a history of gastrointestinal disease — particularly colitis, as antibiotic-associated colitis including C. difficile infection is a risk with any broad-spectrum antibiotic
- Are pregnant or breastfeeding — use only when benefit clearly outweighs risk as assessed by your doctor
- Are taking anticoagulants — Cefixime may affect anticoagulant activity
- Have diabetes — some Cefixime formulations may contain sucrose; confirm with your pharmacist
Side Effects
Common (mild and usually transient):
- Diarrhoea or loose stools — the most common side effect; usually mild and resolves after completing the course
- Nausea or stomach discomfort — reduced by taking with food
- Abdominal pain or bloating
- Mild headache
- Mild skin rash or itching in some patients
Serious — Stop Use and Seek Medical Attention Immediately:
- Severe allergic reaction / anaphylaxis — sudden widespread rash, hives, swelling of face, lips, tongue or throat, difficulty breathing, rapid heartbeat, dizziness — this is a life-threatening emergency (یہ طبی ہنگامی صورتحال ہے)
- Antibiotic-associated colitis (C. difficile) — severe watery or bloody diarrhoea during or after antibiotic treatment, abdominal cramps, fever — stop antibiotic immediately and seek medical attention; C. difficile colitis can be serious if untreated
- Stevens-Johnson Syndrome / severe skin reactions — widespread blistering, peeling skin, painful mouth sores — rare but life-threatening; stop immediately
- Liver effects — yellowing of skin or eyes (یرقان), dark urine, severe fatigue — rare but reported with cephalosporins
- Seizures — rare, particularly in patients with kidney impairment receiving unadjusted doses
Drug Interactions
| Medicine / Substance | Possible Interaction |
|---|---|
| Warfarin and anticoagulants | Cefixime may enhance anticoagulant effect — INR monitoring recommended during treatment |

Frequently Asked Questions
Why must I complete the full course of Cefspan even when I feel better?
Feeling better during antibiotic treatment means the bacterial population has been significantly reduced — but not yet fully eliminated. Stopping the course early leaves a surviving bacterial population that can rapidly regrow, cause a relapse of infection, and — critically — develop resistance to Cefixime. Antibiotic resistance develops precisely when bacteria are exposed to partial courses that reduce but do not eliminate them. Completing the full course ensures the infection is fully eradicated and helps preserve Cefixime's effectiveness for future use in both you and the broader community.
I am allergic to Penicillin — can I still take Cefspan?
This requires careful assessment by your doctor before taking any cephalosporin. There is a degree of cross-reactivity between penicillins and cephalosporins — historically estimated at up to 10%, though more recent research suggests the true cross-reactivity rate with modern third-generation cephalosporins like Cefixime is considerably lower. The risk depends on the nature of your penicillin allergy — a mild rash is very different from anaphylaxis. Always disclose your penicillin allergy history to your doctor before any cephalosporin is prescribed so the benefit-to-risk assessment can be made correctly for your situation.
Is Cefspan effective for typhoid fever — how common is it used for this in Pakistan?
Yes — Cefixime is one of the most widely used oral antibiotics for typhoid fever in Pakistan and is specifically recommended in local treatment guidelines for uncomplicated typhoid. Salmonella typhi — the bacterium responsible for typhoid — is highly susceptible to third-generation cephalosporins. Cefixime's oral availability, once-daily dosing, and effectiveness against even fluoroquinolone-resistant typhoid strains make it particularly valuable in Pakistan's context where typhoid is endemic and multidrug-resistant strains are increasingly common. Treatment duration is typically 7 to 14 days as directed by your doctor based on clinical response.
Can Cefspan cause diarrhoea — when should I be concerned?
Mild loose stools or diarrhoea during antibiotic treatment is common and usually not serious — it results from Cefixime disrupting the normal gut bacterial flora. This typically resolves after completing the course. However, severe watery or bloody diarrhoea — particularly accompanied by abdominal cramps and fever — during or after antibiotic use can indicate Clostridioides difficile (C. difficile) colitis, a serious antibiotic-associated gut infection. If you develop severe diarrhoea, stop Cefspan and consult your doctor immediately — C. difficile colitis requires specific medical treatment and can become dangerous if left untreated.
Can Cefspan 400mg be taken once daily or does it need to be split into two doses?
Cefixime 400mg can be taken either as a single 400mg once-daily dose or split as 200mg twice daily — both regimens achieve equivalent therapeutic outcomes as demonstrated in clinical studies. Once-daily dosing is more convenient for most patients and generally supports better adherence. Twice-daily dosing may be preferred in severe infections or when gastrointestinal tolerance is a concern, as splitting the dose reduces peak drug concentration in the gut. Your doctor will specify the dosing frequency most appropriate for your infection type and severity.
