Semisynthetic tetracyclines require a prescription from a licensed medical professional. Never attempt to obtain them illegally; doing so is risky and illegal.
Your doctor will assess your condition and determine if a semisynthetic tetracycline is the appropriate treatment. They will consider potential drug interactions and your medical history. Always inform your doctor about all medications you are currently taking, including over-the-counter drugs and supplements.
Follow your doctor’s instructions carefully regarding dosage and duration of treatment. Do not stop taking the medication prematurely, even if you feel better. Incomplete treatment can lead to antibiotic resistance.
Common side effects include nausea, diarrhea, and vomiting. More serious, though rare, side effects can occur. Report any concerning symptoms to your doctor immediately. For example, persistent diarrhea might indicate a serious infection like *Clostridium difficile* colitis.
Reputable pharmacies are the only safe source for prescription medications. Avoid online pharmacies or other unofficial sources that don’t require a prescription. These sources often sell counterfeit or contaminated drugs.
If you have questions about cost, discuss potential assistance programs or generic options with your doctor or pharmacist. They can help you find affordable access to necessary medications.
