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.
Lamisil is an antifungal medication for treating athlete’s foot and jock itch, along with fungal infection treatment for toenails and fingernails. It may also be prescribed for ringworm infection treatment or to treat pityriasis that causes lightening or darkening of the skin. Terbinafine is an allylamine antifungal and works by stopping the fungus’ ability to grow. You can buy Lamisil tablets with a prescription here at Canpharm.

How to protect your liver while taking Lamisil?
To protect your liver while taking Lamisil (terbinafine), it’s important to follow the prescribed dosage and avoid excessive alcohol consumption. Your doctor may also monitor your liver function through blood tests during treatment, especially if you have liver problems or are taking other medications that may affect the liver.
How long does it take for Lamisil to work?
Lamisil typically begins to show results within a few weeks, but it may take several months for the full effects to be noticeable, especially in cases of fungal nail infections. For skin infections, improvement is usually seen in 2–4 weeks.
Can you take Lamisil with antibiotics?
Lamisil can generally be taken with antibiotics, but it’s important to inform your doctor about all medications you are taking to avoid potential drug interactions. Certain antibiotics can interact with Lamisil, so your doctor will consider this when prescribing.
How long does Lamisil stay in your system?
Lamisil has a relatively long half-life of approximately 36 hours. It can take about 1–2 weeks for the medication to be completely cleared from the system after the last dose.
Can you drink alcohol on Lamisil?
It is recommended to avoid alcohol while taking Lamisil. Drinking alcohol can increase the risk of liver problems, as both alcohol and Lamisil can stress the liver.
Can Lamisil pills treat yeast infections?
Lamisil pills are not typically used for yeast infections, which are caused by fungi like Candida. Lamisil is effective against dermatophyte fungi that cause infections like athlete's foot, ringworm, and fungal nail infections.
Can you use Lamisil while pregnant?
Lamisil should be used during pregnancy only if clearly needed and prescribed by your doctor. The potential risks to the fetus should be considered before use, as it is not recommended unless the benefit outweighs the risk.
Does Lamisil affect birth control?
Lamisil is not known to interfere with birth control methods, but it’s always a good idea to discuss your medication regimen with your doctor to ensure that everything is compatible and effective.
