Infection treatment: practical steps to start feeling better

Got an infection and not sure what to do first? Start simple: identify the likely type (bacterial, fungal, viral, or parasitic), treat symptoms at home when safe, and get the right medicine when needed. This page gives clear, practical advice on common treatments, safe buying tips, and fast signs that mean you should see a clinician.

Common treatments by type

Bacterial infections usually need antibiotics. Typical choices include amoxicillin for many ear, throat, and skin infections and azithromycin (Zithromax) for some respiratory infections. Certain infections need specialist drugs—Dapsone is used for specific skin infections, and ethionamide is part of TB treatment. Always follow your prescriber's dose and finish the full course unless they tell you otherwise—stopping early can breed resistance.

Fungal infections often respond to topical or oral antifungals. For athlete's foot and toenail fungus, terbinafine (Lamisil) is a common and effective option. Use topical creams as directed and keep the area dry; for stubborn nail infections, oral therapy may be needed and should be supervised by a provider.

Viral infections sometimes need antivirals. Cold sores and herpes are commonly treated with acyclovir (Zovirax). Many mild viral illnesses rely on rest, fluids, and symptom control, but antivirals can shorten or blunt outbreaks when started early.

Parasitic infections require specific antiparasitic drugs—treatment depends on the parasite. If you suspect parasites (prolonged stomach upset after travel, blood in stool, or unexplained itching), get a stool test or medical review before buying meds online.

Safe buying, dosing tips, and warning signs

Want to buy meds online? Use reputable pharmacies and check reviews. Our guides cover how to spot safe sites, what to ask for a prescription, and where fake meds hide. Never buy prescription antibiotics, antivirals, or specialized drugs without a valid prescription. If a site sells powerful drugs without questions, it’s a red flag.

Practical dosing tips: weigh the dose to your child’s weight for pediatric meds, space antibiotics evenly through the day, and avoid mixing certain drugs with alcohol or grapefruit unless cleared by your pharmacist. Keep a list of allergies and current medicines to prevent dangerous interactions.

Know when to see a doctor now: high fever (>38.5°C or 101.5°F), breathing trouble, rapidly spreading redness or swelling, severe pain, confusion, or symptoms that get worse after 48–72 hours on treatment. Babies, older adults, and people with weak immune systems should get prompt medical attention for any sign of infection.

Home care matters. Rest, fluids, good wound hygiene, and over-the-counter pain relief help most people while meds do their job. If you’re buying drugs online, double-check the label, expiration date, and return policies. When in doubt, ask a pharmacist or your healthcare team—better safe than sorry.
