Delstrigo is an oral drug, and it shall be used according to the general guidelines provided as follows:

• Once Daily: The typical dosage of one tablet daily, administered once daily; either with or without food is best from a dosing schedule that also minimizes remembering any details.
• Tablet should be swallowed whole; do not chew, crush, or split.
• Delstrigo should be taken at the same time each day for better effectiveness. In case of interruption of treatment due to any reason or failure to take drugs, the effectiveness of drugs reduces gradually. Eventually, the body develops resistance to drugs.
• If you forget to take a dose, take it when you remember. However, if it is close to the time for your next dose, just omit the dose and continue with the next one scheduled for you. You should never take two doses together in order to catch up with a missed dose.

Always follow the prescription instructions by your doctor and always ensure that you make regular follow-up visits to check on your progress while on the treatment.

Delstrigo is a drug that acts against HIV at all of its late stages in the life cycle. The three active ingredients in Delstrigo work differently to mediate against the virus and thus prevent multiplication and spread within the body.

• Doravirine is a non-nucleoside reverse transcriptase inhibitor. This drug inhibits the reverse transcriptase enzyme; this enzyme is crucial for the replication process of HIV. Ensuring that this enzyme is inhibited will ensure the halt of viral multiplication and replication in the body.
• Lamivudine: This is an NRTI. Lamivudine acts by inhibiting reverse transcriptase through a mechanism not described above. It thus prevents HIV from making new RNA copies, which is necessary for virus survival and reproduction.
• Tenofovir Disoproxil Fumarate: This drug falls into the category of NRTIs. It prevents viral RNA, thereby synthesizing more copies which enable the disease from HIV, and it even rules out resistance to treatment.

The three medicines act in synchrony. HIV titre in the blood decreases and retardation in the condition comes, and also the immunological system works right.

As with any drug, Delstrigo causes side effects. Not everyone experiences them, but there are common side effects and some serious ones that may appear.

• Headache: In a few patients, patients who are on Delstrigo may develop headache.
• Diarrhea: Diarrhoea is quite common with all antiretroviral drugs.
• Nausea: In some patients, nausea may present especially at the beginning of the first month of treatment.
• Fatigue: It may make a patient feel tired.

Serious Adverse Reactions:

• Liver disease: Delstrigo may lead to liver disease like inflammation or liver injury. Your physician will monitor your liver function at regular periods while receiving treatment.
• Kidney Problems: Tenofovir disoproxil fumarate is one of the ingredients in Delstrigo and may affect your kidneys. Therefore, regular assessment of kidney functions is required.
• Bone Health: Tenofovir may lower bone mineral density. This results in an increased risk of osteoporosis leading to fractures in old age.
• Pancreatitis: Although uncommon, lamivudine might cause inflammation in the pancreas. This situation requires stopping of the drug.

Any of the following signs or symptoms must be promptly brought to the attention of a health care provider: yellowing of the skin or eyes can suggest liver disease; severe abdominal pain may be pancreatitis; shortness of breath.

The patient should be advised about the following warnings and precautions prior to using Delstrigo.

• Allergic Reaction: In case of known hypersensitivity to any of the ingredients in Delstrigo, the drug should not be taken. As mentioned above, serious allergic reactions can be fatal and need immediate medical attention.
• Liver Disease: Patients with pre-existing liver disease should exercise caution when taking Delstrigo. Your physician will monitor your liver function closely during treatment.
• Kidney Disease: Tenofivir causes kidney damage; thus, if the patient has a disease of kidneys, the dosage might need adjustment or the patient should receive another form of treatment.
• Pregnancy: The use of Delstrigo during pregnancy should be done only when really needed. Pregnancy should immediately be reported to your doctor; pregnancy will raise concerns about the risk to the fetus and the benefits of using Delstrigo during pregnancy.
• Resistance in HIV: Resistance can be developed if one does not follow the treatment dosages or regimes, and in such cases, you may become resistant to certain drugs in the medication Delstrigo, hence decreasing the efficacy of drugs.

Delstrigo may interact with other medications, which can either reduce its effectiveness or cause undesirable effects. Some of the major known interactions include:

Other HIV Drugs: The Delstrigo medication could interact with other antiretroviral drugs. Therefore, do not forget to inform your health care provider about all the other HIV medications that you might be using.

Other drugs are antifungal. Some examples are ketoconazole, which is an antibiotic to treat a fungal infection and some others, that may increase doravirine level in your blood, and there is the potential side effect from this drug.

• TB medicines: The HIV patient, known as Delstrigo, first-line medication could be interfered with if such a patient utilizes Rifampin. It amplifies the two active ingredients metabolisms hence, diluting Delstrigo effect.
• Herbal Supplements: A depression drug for example St. John’s Wort may jeopardize the HIV medicine; therefore, Delstrigo
• All medicines should be disclosed to your doctor so that no unwanted reaction from the over the counter or herbs may happen to you.

Delstrigo should be taken once daily at a dosage of one tablet that contains 100 mg of doravirine, 300 mg of lamivudine, and 300 mg of tenofovir disoproxil fumarate. The tablets must be swallowed whole, with or without food, and never omitted as this would increase the possibility of weakening the efficacy of treatment.

For patients suffering from severe renal impairment, then the use of Delstrigo will not be acceptable. The doctor will normally give the dosages as they control the medication considering the health conditions of the patients.

Delstrigo can only be prescribed by a doctor. Therefore, it provides a proper dose for the HIV infection and has been observed over the patient due to the onset of possible adverse effects and complications. Your treating physician will conduct follow-up on your health check-up and amend your treatment based on the diagnosis. Never provide your medication to someone else; each patient needs a different set of HIV drug therapy.
