Fasigyn Prescribing Information
Fasigyn is a brand name for the generic medication called Tinidazole. It is an antibiotic and antiprotozoal medication used to treat various types of infections caused by bacteria and certain parasites. Tinidazole is particularly effective against infections that are anaerobic, meaning they thrive in environments with little or no oxygen.
Uses of Fasigyn
Fasigyn is a medication with a range of uses primarily in treating infections caused by bacteria and certain parasites. Here are some specific uses:
- Bacterial Vaginosis: Fasigyn is often prescribed to treat bacterial vaginosis, which is a common vaginal infection caused by an overgrowth of harmful bacteria in the vagina. Symptoms may include unusual vaginal discharge, itching, and odor.
- Trichomoniasis: Medicine is effective in treating trichomoniasis, a sexually transmitted infection (STI) caused by the parasite Trichomonas vaginalis. It can cause symptoms like vaginal itching, discharge, and discomfort during urination.
- Amoebiasis: Fasigyn is used to treat amoebiasis, an intestinal infection caused by the parasite Entamoeba histolytica. It can cause symptoms such as abdominal pain, diarrhea, and weight loss.
- Giardiasis: Antibiotic is effective against giardiasis, an intestinal infection caused by the parasite Giardia lamblia. This infection can lead to symptoms like diarrhea, abdominal cramps, and nausea.
- Anaerobic Bacterial Infections: Fasigyn can be used to treat various infections caused by anaerobic bacteria, which thrive in low-oxygen environments. These infections can affect different parts of the body, including the abdomen, skin, and respiratory tract.
It's important to note that Fasigyn should only be used under the guidance of a medical professional. The dosage, duration of treatment, and specific use of the medication will depend on the type of infection being treated and the individual's medical history.
The dosage of Fasigyn can vary depending on the type of infection being treated, the severity of the infection, and the individual's age, weight, and overall health. Below are some general dosage guidelines for different conditions:
- The typical adult dose is a single 2-gram (2000 mg) dose of Fasigyn taken as a single oral tablet.
- The typical adult dose is a single 2-gram (2000 mg) dose of Fasigyn taken as a single oral tablet.
- For the treatment of partners who are asymptomatic carriers of trichomoniasis, a single 2-gram dose can also be prescribed.
- For intestinal amoebiasis, the usual adult dose is 2 grams of Tinidazole taken as a single dose daily for 2 or 3 days.
- For amoebic liver abscess, the usual adult dose is 2 grams taken as a single dose daily for 3 to 5 days.
The usual adult dose is 2 grams of Fasigyn taken as a single dose daily for 2 days.
Anaerobic Bacterial Infections:
- The usual adult dose for anaerobic bacterial infections is 2 grams of Fasigyn taken once daily for 3 to 5 days.
Fasigyn can be taken with or without food. It's important to complete the entire prescribed course of treatment even if you start feeling better, as stopping the medication prematurely could allow the infection to return or become resistant to treatment.
Side Effects of Fasigyn
Fasigyn is generally well-tolerated, but like any medication, it can cause side effects in some individuals. Not everyone will experience these side effects, and they can vary in terms of severity. Here are some potential side effects:
Common Side Effects:
- Upset stomach or abdominal pain
- Metallic taste in the mouth
Less Common Side Effects:
- Allergic reactions (rash, itching, swelling)
- Dry mouth
- Changes in appetite
- Fatigue or weakness
- Darkening of urine (harmless effect)
- Changes in blood counts (rare)
Serious Side Effects (Rare):
- Severe allergic reactions (difficulty breathing, swelling of the face or throat)
- Severe skin reactions (rash, blisters, peeling)
- Neurological symptoms (tingling, numbness, seizures)
- Changes in mood or mental health
It's important to note that Fasigyn can interact with alcohol, causing a disulfiram-like reaction, which can lead to symptoms such as nausea, vomiting, and flushing. Therefore, it's generally advised to avoid alcohol consumption while taking tablets and for at least 3 days after completing the course of treatment.
Interaction with other drugs
Fasigyn can interact with other drugs, potentially affecting their effectiveness, increasing the risk of side effects, or causing other health complications. Here are some notable interactions:
- Alcohol: Combining Tinidazole with alcohol can lead to a disulfiram-like reaction, causing symptoms like nausea, vomiting, flushing, and increased heart rate. It's important to avoid alcohol while taking this drug and for at least 3 days after completing the course of treatment.
- Warfarin: Medicament may increase the effects of warfarin, a blood-thinning medication, potentially leading to an increased risk of bleeding. Monitoring of your blood clotting time may be necessary if you're taking both medications.
- Lithium: Fasigyn may increase the levels of lithium in the blood, potentially leading to lithium toxicity. If you're on lithium therapy, your lithium levels should be monitored closely.
- Cimetidine: Cimetidine, used to treat stomach ulcers and acid reflux, can increase the levels of Fasigyn in the blood, potentially increasing the risk of side effects.
- Fluorouracil: Combining Tinidazole with fluorouracil, a chemotherapy medication, may increase the risk of side effects such as neurotoxicity.
- Phenytoin: Phenytoin, an antiepileptic drug, can decrease the effectiveness of Fasigyn.
- Certain Blood-Thinning Medications: Antibiotic might enhance the effects of certain blood-thinning medications, potentially increasing the risk of bleeding.
- Medications that Interact with Liver Enzymes: Fasigyn is metabolized in the liver, so drugs that affect liver enzymes could potentially impact its levels and effectiveness.
What to avoid while on Fasigyn
While taking Fasigyn, there are certain substances and activities you should avoid to ensure your safety and the effectiveness of the medication. Here are some things to avoid while on this medicament:
- Alcohol: Avoid consuming alcohol while taking Tinidazole and for at least 3 days after completing the course of treatment. Combining tablets with alcohol can lead to a disulfiram-like reaction, causing symptoms like nausea, vomiting, flushing, and increased heart rate.
