What is Generic?

What is a Generic Drug?

A generic drug is a copy of the brand-name drug with the same dosage, safety, strength, quality, consumption method, performance, and intended use. Before generics become available on the market, the generic company must prove it has the same active ingredients as the brand-name drug and works in the same way and in the same amount of time in the body.

The only differences between generics and their brand-name counterparts is that generics are less expensive and may look slightly different (eg. different shape or color), as trademarks laws prevent a generic from looking exactly like the brand-name drug.

Generics are less expensive because generic manufacturers don't have to invest large sums of money to develop a drug. When the brand-name patent expires, generic companies can manufacture a copy of the brand-name and sell it at a substantial discount.

Diflucan is an antifungal medication available by prescription and used to treat fungal infections, as well as using Diflucan for yeast infection treatment. It is in the azole antifungal class of drugs, and Diflucan works by taking away the fungus' ability to grow so that the body is able to overcome it and eliminate the infection. As is the case with all fungal infection medications, it is important to finish the entirety of the medication even if it appears that the infection has cleared. Doing so will ensure there is no chance of the infection re-establishing itself. Buy Diflucan from Canpharm and get the best price on it.

Frequently asked questions about Diflucan

How long does it take for Diflucan to work?

Diflucan, a powerful medication frequently used for yeast infections, usually begins to work within 24 hours after ingestion. However, the length of time it takes to clear up a yeast infection completely can vary, often depending on the severity of the infection. For mild to moderate infections, relief is often seen within a few days. If you opt to buy Diflucan for yeast infection, remember that it may take a little longer for more severe or persistent infections.

Is Diflucan over the counter?

Diflucan is generally a prescription medication. However, the accessibility of this medication might differ based on geographical location and specific regulations. Some places may have it available over-the-counter, but it is generally recommended to obtain a prescription. Options like Diflucan generic are available on sites like CanPharm, which could be purchased following a prescription from your healthcare provider.

How long does Diflucan stay in your system?

Diflucan's half-life, which is the time taken for the body to eliminate half of the drug, is about 30 hours. So, to fully expel the drug from the system, it might take around five to seven days. However, this could vary depending on individual factors like age, overall health, and metabolic rate. If you decide to buy Diflucan, it's important to keep these considerations in mind.

Is Diflucan an antibiotic?

While Diflucan is a medication that combats infections, it's not classified as an antibiotic. Instead, it is an antifungal medication. Specifically, Diflucan works to treat fungal infections, like yeast infections, by inhibiting the growth of the fungi causing the problem. Diflucan generic, a more affordable option available at places like CanPharm, works in the same way.

Can you take Diflucan while pregnant?

Taking Diflucan while pregnant is a topic that requires careful consideration. While the medication is generally effective for treating yeast infections, its safety during pregnancy is something to discuss with your healthcare provider. Although studies on this topic have had varying results, it is crucial to weigh the benefits and potential risks before starting any new medication during pregnancy.
