🔬 How This Medicine Works (Pharmacology)
Pharmacokinetics
How It Works
This medicine works by binding to specific penicillin-binding proteins (PBPs) located inside the bacterial cell wall. This binding inhibits the transpeptidation step of peptidoglycan synthesis, which is essential for the cross-linking of the bacterial cell wall. As a result, the cell wall becomes weak and the bacteria undergo lysis and death. This medicine is bactericidal, meaning it kills the bacteria directly. It is effective only against actively dividing bacteria.
Mechanism Steps
💡 How to Take pentids 400 tablet
Strength: Tablet containing Penicillin G 400,000 IU (equivalent to 250 mg)
Dosage Information
| Adult Dosage | The usual adult dose of this medicine for most infections is 400,000 IU (250 mg) to 800,000 IU (500 mg) every 6 to 8 hours, depending on the type and severity of the infection. For streptococcal pharyngitis, the typical dose is 400,000 IU every 6 hours for 10 days. For syphilis, higher doses may be used. Dose must be individualized by a qualified clinician based on indication, age, weight, renal and hepatic function. |
| Pediatric Dosage | Pediatric dosing is not established from available information. Consult a pediatrician for appropriate dosing in children. |
| Elderly Dosage | Elderly patients may have reduced kidney function, which can lead to higher blood levels of penicillin G. Dose adjustment may be necessary based on renal function. Elderly patients should be monitored for signs of toxicity, such as seizures. |
| Renal Impairment | In patients with renal impairment, the dose of penicillin G should be reduced or the dosing interval prolonged. For creatinine clearance less than 10 mL/min, the dose should be reduced to 25-50% of the usual dose. Consult a doctor for specific adjustments. |
| Hepatic Impairment | No specific dosage adjustment is required for hepatic impairment, as penicillin G is minimally metabolized by the liver. |
| Maximum Daily Dose | The maximum daily dose for oral penicillin G is not well established, but typical maximum is 4,000,000 IU (2.5 g) per day in divided doses. Higher doses may be used in severe infections under medical supervision. |

🤱 Lactation Safety
Penicillin G is excreted in breast milk in low concentrations. It is generally considered safe during breastfeeding. However, monitor the infant for diarrhea, thrush, or skin rash. If these occur, consult a pediatrician. The benefits of breastfeeding should be weighed against the potential risks.
💊 Overdose Management
Overdose of this medicine may cause nausea, vomiting, diarrhea, and electrolyte imbalance. In severe cases, especially in patients with kidney disease, it may cause seizures. There is no specific antidote. Treatment is supportive and symptomatic. In case of overdose, contact a poison control center or emergency room immediately. Hemodialysis may be considered to remove penicillin G from the blood in severe cases.
⏰ Missed Dose
If you miss a dose, take it as soon as you remember. However, if it is almost time for your next dose, skip the missed dose and continue with your regular schedule. Do not take a double dose to make up for a missed one. Try to take the medicine at evenly spaced intervals to maintain effective blood levels.
Additional Safety Advice
Before taking this medicine, inform your doctor if you are allergic to penicillin or any other antibiotics. Tell your doctor about all other medicines you are taking, especially blood thinners, methotrexate, and oral contraceptives. Take this medicine exactly as prescribed by your doctor. Do not skip doses or stop early. Take it with a full glass of water, with or without food. If you develop a rash, itching, or swelling, stop the medicine and contact your doctor immediately. If you have kidney disease, your doctor may need to adjust your dose. This medicine may reduce the effectiveness of oral contraceptives, so use an additional method of birth control while taking it. Avoid alcohol while taking this medicine as it may worsen stomach upset. Keep this medicine out of reach of children.
👴 Special Considerations for Elderly
💡 For Patients Above 65
Elderly patients are more likely to have reduced kidney function, which can lead to higher blood levels of penicillin G and an increased risk of side effects, including seizures. Dose adjustment based on renal function is recommended. Elderly patients should be monitored for signs of toxicity and allergic reactions.
🤰 Pregnancy Planning (TTC)
If you are planning to become pregnant, discuss with your doctor before taking this medicine. Penicillin G is generally considered safe during pregnancy, but it is important to use it only when clearly needed. If you become pregnant while taking this medicine, inform your doctor immediately.
🏥 Post-Surgery Considerations
If you are undergoing surgery, inform your surgeon and anesthesiologist that you are taking this medicine. It may interact with certain medications used during surgery. In some cases, antibiotics like penicillin G are used prophylactically before surgery to prevent infection. Follow your doctor's instructions regarding timing and dosing.
🦷 Dental Procedures
Inform your dentist if you are taking this medicine. It may be used prophylactically before dental procedures in patients with certain heart conditions to prevent infective endocarditis. If you are allergic to penicillin, your dentist may prescribe an alternative antibiotic.
💚 Lifestyle Tips for Better Results
🏋️ Exercise Considerations
While taking this medicine, you can continue light exercises if you feel up to it. However, if you experience dizziness, fatigue, or muscle pain, take it easy. Avoid strenuous activities until you have recovered from the infection. If you have a fever, it is best to rest.
🥗 Diet Recommendations
💼 Impact on Daily Work & Life
This medicine may cause dizziness or seizures in rare cases, especially in patients with kidney disease. If you experience any such symptoms, avoid driving or operating heavy machinery. Otherwise, it usually does not affect your ability to work. However, if you have a fever or feel unwell, it is best to rest and recover.
🛑 When to Stop This Medicine
Do not stop taking this medicine without consulting your doctor, even if you feel better. Stopping early can lead to recurrence of infection and antibiotic resistance. If you experience severe side effects, your doctor may advise you to stop and switch to another antibiotic. Always complete the prescribed course unless told otherwise by your healthcare provider.
📅 Long-Term Use Effects
Long-term use of this medicine is not common, but prolonged therapy may lead to overgrowth of non-susceptible organisms, including fungi, which can cause conditions like oral thrush or vaginal yeast infections. It may also increase the risk of antibiotic resistance. Regular monitoring of kidney function is advised if used for extended periods, especially in patients with kidney disease. If you need to take this medicine for more than 2 weeks, your doctor may monitor your blood counts and kidney function.
