When Does Terbinafine Start to Work?
Terbinafine is a prescription medication that belongs to the category of systemic antifungal drugs. The brand names of terbinafine under which they are sold are Lamisil and Terbinex.
It works by inhibiting the growth of fungus and helps to treat various skin diseases, particularly fungal infections caused typically by dermatophytes or Candida species. Fungal nail infections may also be treated using this drug.
This drug is relatively safe and has a higher cure rate among other drugs of the similar category. Moreover, the side effects are the least harmful in comparison. Hence, Terbinafine is considered as one of the best choices of drugs for years with higher cure rates to treat diseases caused by fungus
But there is a common complaint among the consumers – the variable duration of recovery taken by Terbinafine. A lot of the users said they could recover within a few days. Meanwhile, others having the same type of infection on the same location of the body said their recovery process took a long time and there were additional side effects that followed.
Here is a brief description that highlights the efficiency of this widely used antifungal drug.
Duration of Recovery
Terbinafine is a drug that takes a variable amount of time to show its effectiveness in order to cure the infection. The duration of the recovery process will depend on multiple conditions which need to be taken under consideration.
Unlike most other remedies, Terbinafine takes time to heal the symptoms of fungal diseases. This duration will depend on various factors like what type of infection it is, its location on the body, which type of drug formulation is being used and if there are other pre-existing medical conditions that delay the process of recovery.
Now if we consider the specific diseases for the potency of Terbinafine, then you will get a number of different opinions among the patients. Ringworm infections take 4-6 weeks to heal, athlete’s foot takes 2-6 weeks, surprisingly 3-4 months if you have a fingernail infection. It may take longer too. These infections take less time to heal if you are young.
It usually takes 6 weeks or more to treat infections on fingernails and up to 12 weeks in toenails. If you have an infection on your big toe, it will take longer to heal. If you have already completed the course of medicine and still have the affected skin unhealed and not fully restored to normal, you must discuss this with the doctor.
In this regard, dosing is another factor responsible for the wavering in the recovery process. You can be recommended to use cream or gel and oral tablets according to the nature of the infection. Usually, all forms of the drug- ointments, solutions, spray and tablets are used among consumers.
Most people go for oral tablets as they are good enough to treat skin conditions and show faster response. That doesn’t indicate ointments are not satisfactory enough. You may use it too. However, the types of infection where the affected site lies deep under the nail bed, may require oral tablets because the solution/ointment of Terbinafine is impenetrable to the nails and underlying structures.
Now that you have known about the aspects that can contribute to the usefulness and use of Terbinafine, you might as well distinguish between them. Just because you have a skin condition and you are using Terbinafine doesn’t mean that the medicine is inappropriate and incapable of restoring your health condition to bounce back to normal again.
But don’t you worry about it! With reasonable care and treatment, your skin will get back to its original form in no time. Remind yourself that fungal infections take a little while to heal and these antifungal drugs take a substantial amount of time to rehabilitate the infected skin onto its actual shape.
Nevertheless, do not forget to talk to your doctor if you see side effects and even if you don’t see improvements in the healing process.
